The practice and process of healthy exercise: an investigation of the treatment of exercise abuse in women with eating disorders

A transdiagnostic and translational framework for delineating the neuronal mechanisms of compulsive exercise in anorexia nervosa

OBJECTIVE

The development of novel treatments for anorexia nervosa (AN) requires a detailed understanding of the biological underpinnings of specific, commonly occurring symptoms, including compulsive exercise. There is considerable bio-behavioral overlap between AN and obsessive-compulsive disorder (OCD), therefore it is plausible that similar mechanisms underlie compulsive behavior in both populations. While the association between these conditions is widely acknowledged, defining the shared mechanisms for compulsive behavior in AN and OCD requires a novel approach.

METHODS

We present an argument that a better understanding of the neurobiological mechanisms that underpin compulsive exercise in AN can be achieved in two critical ways. First, by applying a framework of the neuronal control of OCD to exercise behavior in AN, and second, by taking better advantage of the activity-based anorexia (ABA) rodent model to directly test this framework in the context of feeding pathology.

RESULTS

A cross-disciplinary approach that spans preclinical, neuroimaging, and clinical research as well as compulsive neurocircuitry and behavior can advance our understanding of when, why, and how compulsive exercise develops in the context of AN and provide targets for novel treatment strategies.

DISCUSSION

In this article, we (i) link the expression of compulsive behavior in AN and OCD via a transition between goal-directed and habitual behavior, (ii) present disrupted cortico-striatal circuitry as a key substrate for the development of compulsive behavior in both conditions, and (iii) highlight the utility of the ABA rodent model to better understand the mechanisms of compulsive behavior relevant to AN.

PUBLIC SIGNIFICANCE

Individuals with AN who exercise compulsively are at risk of worse health outcomes and have poorer responses to standard treatments. However, when, why, and how compulsive exercise develops in AN remains inadequately understood. Identifying whether the neural circuitry underlying compulsive behavior in OCD also controls hyperactivity in the activity-based anorexia model will aid in the development of novel eating disorder treatment strategies for this high-risk population.

Longitudinal description and prediction of physical inactivity among patients with borderline personality disorder and personality-disordered comparison subjects

BACKGROUND

The physical and psychological benefits of physical activity are well-known, and physical activity has been proven to be a helpful adjunct to psychotherapeutic treatment for many symptomatic disorders, including mood and anxiety disorders. The current study explores physical inactivity levels in patients with borderline personality disorder (BPD). The first aim of this study is to describe the 12-year course of physical inactivity in patients with BPD. The second aim is to examine predictors of physical inactivity, including adversity experiences, comorbid symptomatic (formerly axis I) disorders, medical disorders, and demographic factors.

METHODS

Two hundred and forty-five patients with BPD were interviewed seven times over 12-years of prospective follow-up as part of the McLean Study of Adult Development (MSAD). Patients were categorized as ever-recovered (i.e., patient had experienced a symptomatic and psychosocial recovery from BPD) or never-recovered. At each follow-up, patients reported physical activity levels (minutes of exercise per week) via a semi-structured interview- the Medical History and Services Utilization Interview (MHSUI). Data was collected from June 1992 to December 2018.

RESULTS

Never-recovered patients with BPD were significantly more inactive than their ever-recovered counterparts (p < 0.001). These rates of inactivity remained stable over time for both groups. Two significant multivariate predictors of inactivity were found: obesity (p = 0.003) and PTSD (p < 0.001).

CONCLUSIONS

Non-recovered BPD patients are more likely to be inactive than patients who have recovered. Both clinical and medical factors appear to contribute to inactivity levels in patients with BPD.

Exercise addiction in team sports: A systematic literature review

While regular exercise should be part of the contemporary lifestyle, many people overindulge in it to the point of losing control over their behavior. This condition is known as exercise addiction (EA). Although addiction is an individual phenomenon, and most of the over 1,000 published studies on EA look at individual exercisers, there are studies on team sports athletes, too. Theoretically, these athletes should not manifest exercise addiction, but some studies are projecting the contrary. Therefore, in this literature review, we analyze EA in team athletes. Based on four databases (PsycINFO, SPORTDiscus, Web of Science, and Google Scholar), we located 22 articles conforming to inclusion criteria. These studies suggest a high risk of exercise addiction among team sports participants. While the figures are lower than for individual exercisers, they are in discord with the concept of addiction as a dysfunction, and the lack of a single case of exercise addiction reported (to date) in team sports athletes in the academic literature. In agreement with a recent position paper, we conclude that there are substantial conceptual and measurement errors in exercise addiction research.

Is Pilates effective in improving depressive disorders? A comprehensive overview

Depressive disorders are disabling conditions that account for high social costs. Pilates demonstrated to have several beneficial effects on health. Objective of this manuscript was to systematically review the literature about the effects of Pilates on depressive disorders. A bibliographic search was conducted in the main database sources (Pubmed, Medline, and Scopus). The inclusion criteria consisted of articles written in English language about the effectiveness of Pilates on depressive symptoms. Most of included studies are randomized controlled trials (10 out of 12). The available literature agrees in indicating that Pilates is effective in improving depressive symptoms especially when compared to inactivity and when this practice is administered for a medium-long period (8-16 weeks). In addition, Pilates seems to have at least comparable effectiveness than aerobic exercise. Pilates can be considered a reliable complementary treatment for people with depressive disorders. These findings should be interpreted considering the different types of practice administered as well as the different duration of the programs or rating scales used to assess mood symptoms. Studies with a more homogenous design are needed to confirm and make generalizable the results presented in this review.

Assessment and treatment of compulsive exercise in anorexia nervosa - A combined investigation of Compulsive Exercise Activity Therapy (LEAP) and Compulsive Exercise Test subscales

INTRODUCTION

Compulsive exercise is a transdiagnostic feature of eating disorders which adversely affects aspects of recovery, such as length of hospitalisation, risk of a chronic outcome, and risk of relapse. CompuLsive Exercise Activity TheraPy (LEAP) aims to reduce compulsive exercise through a cognitive behavioural approach. This study aims to investigate the effect of LEAP on compulsive exercise behaviour using subscales of the Compulsive Exercise Test (CET), a measure of exercise in individuals with eating disorders. Predictive validity of the CET's subscales and its ability to predict eating psychopathology are investigated.

METHOD

This study used data from a randomized controlled trial of LEAP (1). Linear mixed modelling was used to investigate the effect of LEAP on compulsive exercise behaviour, and the predictive ability of CET subscales on various outcomes. The CET was compared to other exercise measures to assess its superiority in predicting eating psychopathology.

RESULTS

LEAP was superior in reducing the scores of the CET's Avoidance and Rule Driven Behaviour and Exercise Rigidity subscales. All subscales made a contribution to the respective models. The CET was superior to other measures in predicting eating pathology.

CONCLUSION

The results lend credibility to LEAP's ability to reduce core parts of compulsive exercise. The CET has been found to target important aspects of compulsive exercise behaviour, and has was superior to other exercise measures in predicting eating psychopathology.

The Impact of Anorexia Nervosa and the Basis for Non-Pharmacological Interventions

Anorexia nervosa is a psychiatric disorder with an unknown etiology that is characterized by an individual's preoccupation with their weight and body structure while denying the severity of their low body weight. Due to the fact that anorexia nervosa is multifaceted and may indicate the coexistence of genetic, social, hormonal, and psychiatric disorders, a description of non-pharmacological interventions can be used to ameliorate or reduce the symptoms of this condition. Consequently, the purpose of the present narrative review is to describe the profile's context in the anorexic person as well as the support they would require from their family and environment. In addition, it is aimed at examining preventative and non-pharmacological interventions, such as nutritional interventions, physical activity interventions, psychological interventions, psychosocial interventions, and physical therapy interventions. To reach the narrative review aims, a critical review was conducted utilizing both primary sources, such as scientific publications, and secondary sources, such as bibliographic indexes, web pages, and databases. Nutritional interventions include nutritional education and an individualized treatment for each patient, physical activity interventions include allowing patients to perform controlled physical activity, psychological interventions include family therapy and evaluation of the existence of other psychological disorders, psychosocial interventions include management of the relationship between the patient and social media and physical therapy interventions include relaxation massages and exercises to relieve pain. All these non-pharmacological interventions need to be individualized based on each patient's needs.

Change in adaptive and maladaptive exercise and objective physical activity throughout CBT for individuals with eating disorders

Maladaptive exercise (i.e., exercise that compensates for binge eating or is used to avoid negative consequences of not exercising-like weight gain) is a common eating disorder (ED) behavior, yet, some individuals with EDs only engage in adaptive exercise. CBT for EDs targets reducing maladaptive exercise but does not address adaptive exercise. Thus, research is limited on how adaptive and maladaptive exercise are impacted during CBT for EDs. The current study examined how assessor-rated adaptive and maladaptive exercise and objectively measured physical activity changed over a 12-week CBT treatment among adults with transdiagnostic binge eating and restrictive eating that did and did not engage in maladaptive exercise at the start of treatment (n = 13 non-maladaptive exercise group, n = 17 maladaptive exercise group). The overall amount of adaptive and maladaptive exercise was measured via the Eating Disorder Examination Interview and objectively measured physical activity (e.g., step count, minutes of moderate-to-vigorous physical activity [MVPA]) was measured via a wrist-worn fitness tracker. Throughout treatment, the overall amount of adaptive exercise did not significantly change for both groups, but the overall amount of maladaptive exercise significantly decreased in the maladaptive exercise group. Step count did not significantly change for both groups, but minutes of MVPA significantly increased over treatment for the non-maladaptive exercise group. Increases in step count and minutes of MVPA were not associated with ED symptom changes in either group. These results enhance an understanding of exercise changes during transdiagnostic CBT-based ED treatment for individuals with varying baseline exercise profiles.Level of evidence: Level 1, randomized controlled trial.

Medical and physiological complications of exercise for individuals with an eating disorder: A narrative review

Individuals with eating disorders (ED) experience prolonged malnutrition, binge episodes, and compensatory behaviours that affect every organ system. Psychological and physiological symptoms are worsened with comorbid dysfunctional exercise, seen in up to 80% of those with an ED. Although return to exercise is an important component of treatment and recovery, little is known about the contraindications and risks of exercise engagement specific to those with an ED. This paper provides a comprehensive narrative review of the medical and physiological complications of engaging in exercise during ED treatment and outlines when exercise may be contraindicated or used in modified or cautionary ways. We conducted a literature search on MEDLINE, PubMed, and PsychArticles to identify relevant articles, which yielded six categories of medical and physiological complications of ED that may be exacerbated by exercise: energy availability, cardiovascular health, electrolyte abnormalities, biomedical function markers, sex hormones, and body composition. We summarize the evidence for these complications for readers and offer an initial set of recommendations for incorporating exercise during ED treatment based on our findings. This review may serve as a resource for members of ED treatment teams to help evaluate more readily and confidently whether exercise is safe for individual patients and when modifications and caution may be warranted.

What my body looks like and what my body can do: A self-perception explanation of excessive exercise in young adults with anorexia and/or bulimia

The present study examined the relationships between quantitative and qualitative dimensions of excessive exercise (EE) with the physical self-perception’s dimensions and perceptual perspectives of body image (i.e., allocentric/3rd person and egocentric/1st person perspectives). The eLoriCorps Immersive Body Rating Scale 1.1, the very short form version of the Physical Self-Inventory and the Exercise and Eating Disorder test were used. The study includes 36 people with anorexia and/or bulimia seeking an external and specialized transdisciplinary program for eating disorders. Results show a different correlational profile of physical self-perceptions depending on the dimension (qualitative or quantitative) used to define EE. Differences in the perspectives used to assess body dissatisfaction (allocentric or egocentric) were also found. Perceived physical appearance was the key predictor of the qualitative dimension of excessive exercise. Findings suggest that EE in patients with an eating disorder could be explained by the feeling of competence not only related to physical appearance but also to physical abilities.

Shifting the Focus: A Pilot Study on the Effects of Positive Body Exposure on Body Satisfaction, Body Attitude, Eating Pathology and Depressive Symptoms in Female Patients with Eating Disorders

One of the most commonly used techniques for the treatment of body image problems in eating disorders (ED) is body exposure (BE). However, evidence of its effectiveness in clinical populations is scarce. In the Positive Body Experience (PBE) protocol, the focus of positive BE is on aesthetic, functional and tactile aspects of the body. The current study evaluates the outcomes of positive BE with regard to changes in attitudinal body image and eating pathology, as well as the factors that influence these changes, in a sample of 84 adult female patients with different EDs who did not receive any other treatment for their EDs during the period in which BE treatment occurred. The results show significant positive changes in attitudinal body image, ED behaviors and depressive symptoms, with depressive symptoms at baseline mediating the changes in attitudinal body image. This study indicates that the PBE protocol is a suitable intervention for reducing negative attitudinal body image in anorexia and bulimia nervosa patients, as well as those with binge eating disorder. Furthermore, the results suggest that positive non-weight-related and functional body satisfaction are strong catalysts for change and that depressive symptoms play an important role in the ability to change. Additional RCTs are needed to gain more insight into the effects of PBE.

Inpatient Rehabilitation during Intensive Refeeding in Severe Anorexia Nervosa

Severe forms of anorexia nervosa are responsible for weight loss and life-threatening consequences. Refeeding represents a real psychiatric and somatic challenge. Physical activities are usually not recommended during intensive refeeding in order to avoid energy expenditure. This study assessed the interest in an early return to controlled physical activities, during a hospitalization in a Physical Medicine and Rehabilitation (PMR) department, including continuous nasogastric refeeding and psychiatric care. A total of 37 subjects aged 32 ± 11 years old performed inpatient physical activities during nasogastric refeeding initiated after intensive care. The physical activity program was adapted according to the hyperactivity of the patients. Evaluation parameters were weight, body mass index (BMI), body composition (fat, lean, and bone masses), and function (strength, balance, walking, ventilation). Patient satisfaction, re-hospitalizations, and physical activities continuation were assessed at 12 months of follow-up. Weight, BMI, and body fat increased significantly (+2.7 ± 1.7 kg; +1.0 ± 0.6 kg/m²; +1.7 ± 2.5 kg, respectively). Muscle strength increased even if the lean mass did not. Walking distance, balance, and respiratory function were significantly improved. Weight and fat mass gains did not differ according to the presence or absence of hyperactivity. At 12 months, 46% of the patients continued to be physically active, but 21% of the patients had been re-hospitalized. The early return to controlled physical activities in PMR hospitalization does not compromise the efficiency of intensive refeeding in severe anorexia nervosa patients.

A systematic review of treatment approaches for compulsive exercise among individuals with eating disorders

Individuals with eating disorders often experience compulsive exercise which, if left untreated, can lead to longer treatment and worsened symptoms. Compulsive exercise must be addressed within eating disorder treatment to help individuals establish a healthy relationship with exercise. However, there are currently no standardized guidelines for treating compulsive exercise or a consensus on which forms of treatment are most effective. Therefore, the purpose of this review was to examine interventions that address compulsive exercise and their impact on treating compulsive exercise among individuals with eating disorders. A systematic review of the literature was conducted. Eleven studies testing treatments for compulsive exercise were included in this review. Participants were diagnosed with anorexia nervosa, bulimia nervosa, or EDNOS, and a small portion had BED. Improvements in compulsive exercise and eating psychopathology were observed across all studies. The interventions focused on exercise psychoeducation and often incorporated exercise sessions. The findings highlight the positive impact of treating compulsive exercise, suggesting it should be a standard component of eating disorder treatment. Future studies should examine differences in treatment approaches and outcomes specific to each eating disorder, and specific to males. More consistency across studies in the conceptualization and measurement of compulsive exercises is also needed.

Treatment Considerations for Compulsive Exercise in High-Performance Athletes with an Eating Disorder

Compulsive exercise is linked with poorer treatment outcomes in people with eating disorder (EDs). High-performance athletes represent a growing and complex subcomponent of the broader ED population, and emergent evidence indicates that different conceptualisations of compulsive exercise are needed in this population. Existing randomised controlled trials in ED populations have demonstrated small treatment effects on compulsive exercise compared with control groups; however, athletes were sparsely sampled across these studies. Thus, the extent to which current treatments for compulsive exercise in EDs are also effective in high-performance athletes is unknown. For this opinion paper, we sought representation from high-performance sports leadership, someone with lived experience of both an ED and high-performance athletics, and ED clinical experts. We discuss the utility of recommending exercise abstinence in ED treatment with athletes, as well as a number of other treatment strategies with some evidence in other contexts for further consideration and research in this population. These include using mindfulness-based interventions as an adjunct to cognitive-behavioural therapies, using wearable technologies and self-reported fatigue to inform training decisions, and incorporating greater exercise variation into training programs. We also offer practical considerations for clinicians seeking to apply foundational elements of cognitive-behavioural interventions (e.g., exposure and response prevention, cognitive restructuring, behavioural experiments) into an ED treatment program for a high-performance athlete. Future research is needed to examine characteristics of pathological compulsive exercise in athletes and whether available treatments are both feasible and effective in the treatment of compulsive exercise in athletes with an ED.

Effect of an education and mindfulness-based physical activity intervention for the promotion of positive body image in Lithuanian female students

PURPOSE

The aim of this study was to test the effectiveness of an 8-week classroom education and mindfulness-based physical activity intervention for the promotion of positive body image in female students.

METHODS

A quasi-experimental study was carried out with 110 Lithuanian female students (mean age 21.5 ± 3.5, range 19-35 years). Thirty students voluntarily participated in the intervention programme and 80 students volunteered in the assessment-only control group. The intervention comprised five cognitive behavioural therapy classroom education sessions and mindfulness-based exercise (one exercise workout per week). The intervention group was evaluated with a pre-test and post-test and the control group completed measures at parallel times.

RESULTS

Compared with the control group participants, the intervention group participants reported greater improvements in positive body image and a reduction in body dissatisfaction and drive for thinness and internalisation of stereotyped beauty ideals, with medium to large effects. There were significant time × group interactions for pre-test to post-test changes in internalisation of beauty ideals, body area satisfaction, body dissatisfaction and body appreciation. In all cases, the interaction reflected greater pre-test to post-test changes in the intervention group compared with the control group, whose scores remained stable. A decrease in appearance orientation, overweight preoccupation, disordered eating and physical activity was observed in the control group, but the effect sizes were low.

CONCLUSION

The preliminary findings of this study support the efficacy of cognitive behavioural therapy methods and mindfulness-based exercise intervention aimed to promote positive body image in student-aged women. Future studies should test the efficacy of the introduced programme in larger randomised samples of young women.

Exercise therapy in the treatment of anorexia nervosa: Its effects depending on the type of physical exercise-A systematic review

BACKGROUND AND PURPOSE

Clinical research focusing on the effectiveness of exercise therapy (ET) in patients with anorexia nervosa (AN) shows increasing interest in the last decade. The aim of this systematic review was to provide an overview of quantitative studies that have examined the impact of ET in AN patients and to examine its specific effects on physical and mental health according to the type of physical exercise (PE) practiced.

METHODS

The review was carried out based on the PRISMA 2020. Electronic databases PubMed, Web of Science, Embase, and Wiley were searched from inception to December 2021. Quantitative studies assessing the effects of ET interventions on AN patients were included and study quality was assessed using the PEDro scale.

RESULTS

A total of 27 studies were selected, including 13 randomized controlled trials. Regarding outcomes measured, results showed that aerobic and resistance exercise improved muscle strength, that mind-body PE decreased main symptoms of AN and mental health, and that combined PE reduced dysfunctional exercise and improved weight gain.

CONCLUSION

The findings suggest that ET intervention can induce benefits and has no deleterious effects on patients. In addition, specific effects on anorexia symptoms and physical and mental health have been observed according to the type of PE. However, this review reported several methodological weaknesses, including a lack of control group or randomization and statistical misconduct. Finally, ET intervention parameters were heterogeneous, and ET intervention generally lacked details, making reproducibility and comparability difficult. All these limitations underscore the need for a more rigorous methodology for further research.

Characterizing reasons for exercise in binge-spectrum eating disorders

Although 40-60% of individuals with eating disorders (EDs) report engaging in maladaptive exercise, self-reported reasons for engaging in exercise vary. Further, no studies have examined momentary reasons for exercise and whether reasons for exercising could be both adaptive and maladaptive for any episode. Examining reasons for exercise can inform interventions which more effectively target maladaptive exercise. The current study recruited adults with binge-spectrum EDs (N = 58, 89.2% Female) and assessed self-reported reasons for exercise using ecological momentary assessment over 7-14 days. Exercise episodes were categorized as maladaptive if the participant endorsed exercising to compensate for eating or feeling driven to exercise. On average, participants reported exercising 8 times (SD = 8) over the 7-14 days. On average, 73% of exercise episodes were maladaptive. Participants most frequently stated exercising to control shape or weight (67.2% of episodes), feeling driven (62.9%), and exercising as part of a routine (52.9%). Participants least endorsed exercising so that they could eat more later (9.8%). Participants reported a mean of 3.6 reasons for exercising at each episode (SD = 1.85, mode = 1.0). As hypothesized, individuals with EDs were exercising for several reasons at each exercise episode. Further, the extent to which each exercise episode is maladaptive varied between participants and even within a single participant's exercise episodes. These findings underscore the importance of research evaluating when, and for whom, exercise becomes maladaptive, as well as research examining other characteristic features of maladaptive and adaptive exercise in EDs.

What role can accredited exercise physiologists play in the treatment of eating disorders? A descriptive study

Including exercise alongside other therapeutic approaches may help to address dysfunctional exercise use and improve eating disorder treatment outcomes. However, traditional treatment teams often lack the expertise needed to safely prescribe exercise. The aims of this study were to explore the perceptions and experiences of Accredited Exercise Physiologists (AEPs) relating to working with clients diagnosed with eating disorders to identify the role they play in the treatment of eating disorders and identify future training needs. Individual semi-structured telephone interviews were conducted with 12 (n = 9 females) AEPs working in the eating disorders field. Thematic analysis was conducted to extract major themes from the interview transcripts. Five major themes were identified: (1) The role of AEPs in the treatment of individuals with eating disorders is comprehensive; (2) Treatment is more effective when all components are addressed; (3) The absence of therapeutic exercise within standard treatment protocols reflects limitations of traditional scope of practice and knowledge about the role of AEPs; (4) Methods of acquiring further knowledge are insufficient for those in current practice; and (5) Accredited comprehensive training is currently unavailable but needed. This qualitative study showed that AEPs believe they can play a major role in the treatment of eating disorders and that treatment outcomes for individuals are likely to be greatly enhanced when dysfunctional exercise is addressed. Multidisciplinary training is needed.

A Longitudinal Study of Exercise Addiction and Passion in New Sport Activities: the Impact of Motivational Factors

Recent research suggests that the risk of exercise addiction (REA) is primarily predicted by passion. However, this relationship stems from cross-sectional studies. The objective of this 12-week longitudinal investigation was to examine and compare the temporal changes in REA and passion among women and men (N = 149) who just started a new sport activity. To further test their similarities and distinctiveness, we also examined how exercise motivations predict REA and passion. Latent growth modeling showed that REA and passion were high at baseline and showed a slight increase over the 12 weeks. Passion was predicted by several motivational factors, whereas REA was predicted by being female, team sport participation, higher exercise intensity, and identified motivation. These findings suggest that the development of passion and REA over time, both being associated with sport motivations, manifest independent patterns. Consequently, despite the reported strong relationship between the two, they appear to be independent constructs.

"Compulsive exercise is a socially acceptable prison cell": Exploring experiences with compulsive exercise across social media

OBJECTIVE

Investigations into online eating disorder (ED) communities have allowed for a rich exploration of lived experiences focused on a number of aspects, such as recovery and support groups. There is a lack of understanding around compulsive exercise (CE), which is often a characterizing condition of EDs. Exploring the lived experiences of CE as discussed online could provide helpful insight towards a better understanding of CE. Therefore, the purpose of this study was to explore experiences around CE and EDs shared on social media sites.

METHOD

Social media posts related to CE and EDs from Reddit, Twitter, Instagram, and forums were collected for 12 months. A thematic analysis of 881 posts was used to identify common themes among individuals' lived experiences with CE.

RESULTS

Five themes (and three subthemes) were identified across the social media posts: (1) seeking control, but ultimately CE takes hold, (2) burning off binges, but at what expense?, (3) recovery is a battle, but worth it, (4) is my exercise healthy?, and (5) frustration with comments about CE.

DISCUSSION

The lived experiences of CE among individuals with EDs have provided support for current definitions of CE and shared novel insight into the recovery experience. Individuals online also highlighted the need for improvement in treatment around CE specifically, and greater awareness around CE for the general public and healthcare providers.

Psychosocial etiology of maladaptive exercise and its role in eating disorders: A systematic review

OBJECTIVE

Although maladaptive exercise (ME) is widely recognized as a clinical feature in transdiagnostic eating disorders, less is known about psychosocial factors that give rise to and perpetuate this behavior. This systematic review aimed to examine the empirical status of this association.

METHOD

We reviewed 46 full text articles examining longitudinal associations between psychosocial variables and ME.

RESULTS

Eighteen studies met full inclusion criteria. Based on our qualitative synthesis, evidence suggests reasonably consistent associations between early concern with weight and shape, and negative affect on later development of ME.

DISCUSSION

Inconsistent and insufficient assessment of ME across a majority of studies underscores caution in interpretation of results, but guides important discussion for future clinical and research efforts.

Feasibility, Acceptability, and Preliminary Target Engagement of a Healthy Physical Activity Promotion Intervention for Bulimia Nervosa: Development and Evaluation via Case Series Design

Bulimia nervosa (BN) is characterized by a pattern of binge eating and compensatory behaviors as well as an overemphasis on body weight and shape in self-evaluation. Although cognitive behavioral therapy (CBT) is efficacious, recent reviews suggest that only 30% of patients reach abstinence at posttreatment. One potential reason for these poor outcomes is that CBT fails to adequately reduce elevated negative affect (NA) and shape and weight concern, which have been shown to be correlated with poorer treatment outcomes in BN. Therefore, novel treatment components that focus on improving NA and shape and weight concern are needed in order to enhance outcomes. Promoting physical activity (PA) is a promising avenue through which to reduce NA and improve body image in healthy individuals, other clinical populations (e.g., individuals with depression or anxiety), and individuals with eating disorders. While prescribing PA for individuals with BN has been controversial (due to concerns that exercise maybe be used to compensate for binge episodes or become driven or compulsive), this approach may have many benefits, including promoting healthy lifetime exercise habits that reduce likelihood of relapse through the improvement of emotion regulation skills and weight regulation. Given the promise of PA for targeting key maintenance factors of BN, we developed a 12-session healthy PA promotion intervention for BN and tested initial feasibility, acceptability, and preliminary target engagement in an iterative case series design (n = 3). The treatment provided cognitive-behavioral skills designed to identify, practice, and achieve behavioral goals while asking patients to engage in up to 150 minutes of moderate-to-vigorous PA per week, which was preplanned during each session with the client's therapist. Results suggested that the healthy PA promotion intervention was both feasible and acceptable to deliver. In addition, the intervention resulted in a clinically significant decrease in BN symptom frequency in each participant. Further, participants showed clinically significant decreases in NA and shape and weight concern. The current study demonstrates that healthy PA interventions can have beneficial effects on BN symptoms, NA, and shape and weight concern. However, due to the small sample size, conclusions must be treated with caution. Future research should investigate additional approaches for promoting healthy PA and include a larger sample in order to further test initial efficacy of this treatment approach.

Women, Exercise, and Eating Disorder Recovery: The Normal and the Pathological

The appropriate form, regularity, and intensity of exercise for individuals recovering from eating disorders is not agreed upon among health care professionals or researchers. When exercise is permitted, it is that which is mindful, embodied, and non-competitive that is considered normative. Using Canguilhem's concepts of "the normal and the pathological" as a theoretical frame, we examine the gendered assumptions that shape medical understandings of "healthy" and "dysfunctional" exercise in the context of recovery. The data set for this article comes from longitudinal semi-structured interviews with 19 women in the United Kingdom who engaged in weightlifting during their eating disorder recovery. We argue that women in recovery navigate multiple and conflicting value systems regarding exercise. Faced with aspects of exercise that are pathologized within the eating disorder literature (such as structure/routine, body transformations, and affect regulation), women re-inscribe positive value to these experiences, thus establishing exercise practices that serve them.

Physical activity behaviors and attitudes among women with an eating disorder: a qualitative study

BACKGROUND

Physical activity (PA) is an integral part of healthcare for the general population and individuals with psychiatric disorders. However, PA is significantly more complex for and related to both healthy (e.g., reduced anxiety and depressive symptoms) and unhealthy outcomes (e.g., intrusive, repetitive thoughts that lead to abnormally high levels of PA) among women with an eating disorder (ED). Consequently, many healthcare professionals recommend abstinence from PA during ED treatment. Despite this, women may remain engaged in PA during ED treatment or resume PA shortly thereafter. Little has been done to understand women's PA behaviors and attitudes and to explore how they integrate PA into their lives during and after ED treatment. Thus, this study sought to explore PA behaviors and attitudes among women with an ED.

METHODS

Nine women who self-reported receiving an ED diagnosis participated in semi-structured interviews, which were transcribed and analysed thematically.

RESULTS

Six interrelated themes were constructed to represent participants' PA experiences: PA as a lifestyle, PA can be beneficial, How I feel when I can't do PA, Being cautious about PA, Reactions to healthcare professionals' practice of recommending abstinence from PA during ED treatment, and PA programming thoughts.

CONCLUSIONS

Overcoming dysfunctional PA behaviors (e.g., engaging in abnormally high levels of PA) and attitudes (e.g., associating PA with caloric expenditure) can be a long and complicated journey for women with an ED. Nevertheless, women with an ED want PA to be integrated into their ED treatment protocol for two key reasons, namely to accrue the benefits associated with PA and to learn how to engage in PA in adaptive and healthy ways.

Treatment of compulsive exercise in eating disorders and muscle dysmorphia: protocol for a systematic review

BACKGROUND

Compulsive exercise is a core feature of both eating disorders and muscle dysmorphia. Earlier models of treatment recommended complete abstinence from exercise in eating disorder populations, but recent guidelines advocate for the gradual inclusion of healthier forms of exercise into an overall treatment plan where appropriate. Given the association between problematic exercise behaviour and poorer prognosis, there has been a recent upsurge in the number of treatment interventions for compulsive exercise in eating disorders. However, no systematic review has been published summarising this existing treatment literature. The aim of this review is to determine the efficacy of existing treatments for compulsive exercise in eating disorders and muscle dysmorphia.

METHODS

A systematic review will be conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Five electronic databases (PsycInfo, MEDLINE, Embase, Web of Science, and Scopus) will be searched from database inception until November 2020. We will include studies that: (a) sampled adolescents and/or adults with either an eating disorder or muscle dysmorphia; (b) assessed changes in compulsive exercise from pre- to post-intervention; and (c) used a standardised instrument to measure compulsive exercise or related constructs. We will include studies with a comparison group (e.g., randomised controlled trials) and without a comparison group (e.g., pilot studies and case studies) to provide a comprehensive overview of the literature. One reviewer will screen all titles and abstracts against eligibility criteria, with 20% of excluded articles cross-referenced by another reviewer. Full texts will be obtained for articles deemed relevant or where inclusion was uncertain, and will be screened by both reviewers. We will also evaluate the quality of the included studies using a modified Downs and Black (J Epidemiol Community Health 52:377-384, 1998) assessment checklist.

DISCUSSION

Results from this review will help to determine the most efficacious treatment components for compulsive exercise in eating disorders and muscle dysmorphia. We hope that our results will help inform clinical practice guidelines in recommending targeted interventions for the treatment of compulsive exercise.

The relationship between food addiction and patterns of disordered eating with exercise dependence: in amateur endurance athletes

PURPOSE

Examine the prevalence and potential relationships among food addiction (FA)-as measured by Yale Food Addiction Scale 2.0 (YFAS 2.0), eating disorders (ED)-as measured by Eating Disorder Diagnostic Scale (EDDS)-and exercise dependence (EXD)-as measured by Questionnaire to Diagnose Exercise Dependence in Endurance Sports (FESA), for the first time worldwide, in amateur endurance athletes.

METHODS

A total of 1022 German-speaking endurance athletes (44% male, Ø 36 years, Ø BMI 23 kg/m²) replied to an online questionnaire consisting of demographics, related parameters, and the German versions of YFAS 2.0, EDDS, and FESA.

RESULTS

Prevalence of FA, ED, and EXD was 6.2, 6.5, and 30.5%. The probability for FA increases with BMI, thoughts about food and EXD score, and decreases with age and when an ED is present. People with FA and people with ED vs. people with both, FA&ED, differed significantly in this cohort. Strong significant relationships were found between FA and EXD (X² (1) = 15.117, p < 0.001, n = 1022).

CONCLUSIONS

A considerable number of amateur endurance athletes may suffer from FA. The association between FA and EXD is stronger than between ED and EXD, indicating FA as a potentially more relevant subject-than ED-for prevention or therapy in people with EXD. Further studies are needed to investigate parameters and relationships between the possibly involved types of ED, FA, and EXD.

A conceptual model describing mechanisms for how yoga practice may support positive embodiment

Yoga practice has been associated with various indices of positive embodiment in correlational and intervention studies. Yet, systematic, theoretically-grounded models detailing specific mechanisms by which yoga supports positive embodiment are lacking. In this article, we present a conceptual model that describes mechanisms (i.e., mediators and moderators) that can be used to guide research to help answer how, for whom, and under what conditions yoga practice may promote positive embodiment. Based on existing theoretical frameworks and empirical findings, this model suggests that (a) yoga practice may cultivate embodying experiences during yoga (e.g., state mindfulness), (b) these embodying experiences may build stable embodying experiences that generalize beyond the yoga context (e.g., trait mindfulness), and (c) these stable embodying experiences may then promote embodying practices (e.g., mindful self-care). This mediational chain is likely moderated by the yoga context (e.g., instructional focus, presence of mirrors, diversity of bodies represented) and yoga practitioners' social identities (e.g., body size, physical limitations), social and personal histories (e.g., experiences with weight stigma and trauma), and personality traits and motives (e.g., body comparison, appearance-focused motives to practice yoga). Using the structure of this conceptual model, we offer researchers ideas for testable models and study designs that can support them.

Feasibility and effect of a Pilates program on the clinical, physical and sleep parameters of adolescents with anorexia nervosa

BACKGROUND AND PURPOSE

Anorexia nervosa (AN) becomes chronic, with high physical, psychological and social morbidity and high mortality without early and effective treatment. The impact of physical exercise as a coadjutant to conventional treatment in this clinical population has been studied with favorable results. Although a Pilates program could be beneficial for patients with AN, no study has analyzed its feasibility and effects in adolescents with AN. Therefore, this study evaluated the safety of a Pilates program and investigated the feasibility and effect in adolescents with AN.

MATERIALS AND METHODS

In this prospective quasi-experimental study, body composition, blood analysis, sedentary time, physical activity and time of sleep, and physical fitness were measured objectively before and after a 10-week Pilates supervised program.

RESULTS

Twelve female adolescents with AN (14.6 ± 1.7 years old) completed the program, with a session attendance rate of 96%, a persistence rate of 100%. There were significant increases in height, plasma calcium and sleep efficiency. Significant decreases in plasma follitropin, sleep duration and, duration and number of night perturbations were observed.

CONCLUSION

A Pilates program is safe and feasible in adolescents with AN when they have a controlled and stable weight, and such a program could be a viable alternative among treatment programs to achieve better sleep quality.

The Freiburg sport therapy program for eating disorders: a randomized controlled trial

BACKGROUND

Unhealthy attitudes towards sport and problematic exercise behavior in eating disorders (ED) are common and associated with poorer treatment outcome and higher relapse rates. There is a need to develop and empirically test interventions that could complement standard treatment. The study aimed to assess the efficacy of the Freiburg sport therapy program for eating disorders (FSTP).

METHODS

Outpatients with ED were randomized either to a 3 month sport therapy program (sport therapy group: STG) or a waiting list control group (CG). Patients were assessed when starting the program and at the end of the intervention. The intervention group (STG) was followed up after 6 month. Main outcome criterion was a reduction in unhealthy exercise (Commitment to Exercise Scale, CES). Secondary outcomes encompassed eating pathology (Eating Disorder Examination, EDE), different dimensions of unhealthy exercise (Compulsive Exercise Test, CET subscales) and exercise quantity (accelerometer).

RESULTS

Recruitment was challenging. Fifteen patients were randomized to the STG and 11 were randomized to the CG condition. There was no statistically significant difference between groups according to the main outcome criterion. However, the STG showed a significantly stronger reduction in avoidance and rule driven behavior (CET subscale) when compared to the CG. Improvements (STG) were maintained at follow up.

CONCLUSIONS

There was no statistically significant difference in the reduction of unhealthy attitudes towards sport and problematic exercise behavior between the intervention and the group, as measured with the Commitment to Exercise Scale. Further findings may point to the effectiveness of the program, but have to be interpreted with caution and verified in further studies. A major limitation is the small sample size.

Nutritional Management and Outcomes in Malnourished Medical Inpatients: Anorexia Nervosa

BACKGROUND

Anorexia Nervosa (AN) is a psychiatric disorder characterised by a physical and psychosocial deterioration due to an altered pattern on the intake and weight control. The severity of the disease is based on the degree of malnutrition. The objective of this article is to review the scientific evidence of the refeeding process of malnourished inpatients with AN; focusing on the clinical outcome.

METHODS

We conducted an extensive search in Medline and Cochrane; on April 22; 2019; using different search terms. After screening all abstracts; we identified 19 papers that corresponded to our inclusion criteria.

RESULTS

The article focuses on evidence on the characteristics of malnutrition and changes in body composition; energy and protein requirements; nutritional treatment; physical activity programmes; models of organisation of the nutritional treatment and nutritional support related outcomes in AN patients.

CONCLUSION

Evidence-based standards for clinical practice with clear outcomes are needed to improve the management of these patients and standardise the healthcare process.

Strength and Power Improvements in Athlete and Non-Athletes During Intensive Eating Disorder Treatment

Understanding the unique needs of athletes who undergo eating disorder (ED) treatment is sorely needed. This study explores changes of strength and power in athlete (n = 21) and non-athlete (n = 36) patients from intake to discharge. Maximal oxygen consumption, vertical jump, push-ups, hand grip strength, and body mass index (in anorexia nervosa; AN) were measured among treatment center patients. The number of push-ups and hand grip strength were significantly improved upon discharge in the full sample (ps < .005) and in AN only (ps < .001). Body mass index was also significantly higher in AN (p < .001). Maximal oxygen consumption and vertical jump did not significantly improve between admission and discharge in either group (ps > .40). This study is the first to investigate measures of strength in athletes engaged in intensive eating disorder treatment and indicates the need to address the psychological mindset around physical activity using exercise education as part of a comprehensive program. Recommendations for incorporating exercise into an intensive ED treatment center are also provided.

The Role of Objectively Measured, Altered Physical Activity Patterns for Body Mass Index Change during Inpatient Treatment in Female Patients with Anorexia Nervosa

Increased physical activity (PA) affects outcomes in patients with anorexia nervosa (AN). To objectively assess PA patterns of hospitalized AN patients in comparison with healthy, outpatient controls (HC), and to analyze the effect of PA on Body Mass Index (BMI) change in patients with AN, we measured PA in 50 female patients with AN (median age = 25 years, range = 18–52 years; mean BMI = 14.4 ± 2.0 kg/m²) at the initiation of inpatient treatment and in 30 female healthy controls (median age = 26 years, range = 19–53 years; mean BMI = 21.3 ± 1.7 kg/m²) using the SenseWear™ armband. Duration of inpatient stay and weight at discharge were abstracted from medical records. Compared with controls, AN patients spent more time in very light-intensity physical activity (VLPA) (median VLPA = 647 vs. 566 min/day, p = 0.004) and light-intensity physical activity (LPA) (median LPA = 126 vs. 84 min/day, p < 0.001) and less time in moderate-intensity physical activity (MPA) (median MPA = 82 vs. 114 min/day, p = 0.022) and vigorous physical activity (VPA) (median VPA = 0 vs. 16 min/day, p < 0.001). PA and BMI increase were not associated in a linear model, and BMI increase was mostly explained by lower admission BMI and longer inpatient stay. In a non-linear model, an influence of PA on BMI increase seemed probable (jack knife validation, r² = 0.203; p < 0.001). No direct association was observed between physical inactivity and BMI increase in AN. An altered PA pattern exists in AN patients compared to controls, yet the origin and consequences thereof deserve further investigation.

Self-reported quantity, compulsiveness and motives of exercise in patients with eating disorders and healthy controls: differences and similarities

BACKGROUND

Compulsive exercise (CE) is a frequent symptom in patients with eating disorders (EDs). It includes, in addition to quantitatively excessive exercise behaviour, a driven aspect and specific motives of exercise. CE is generally associated with worse therapy outcomes. The aims of the study were to compare self-reported quantity of exercise, compulsiveness of exercise as well as motives for exercise between patients with anorexia nervosa (AN), bulimia nervosa (BN) and healthy controls (HC). Additionally, we wanted to explore predictors of compulsive exercise (CE) in each group.

METHODS

We investigated 335 female participants (n = 226 inpatients, n = 109 HC) and assessed self-reported quantity of exercise, compulsiveness of exercise (Compulsive Exercise Test), motives for exercise (Exercise Motivations Inventory-2), ED symptoms (Eating Disorder Inventory-2), obsessive-compulsiveness (Obsessive-Compulsive Inventory-Revised), general psychopathology (Brief Symptom Inventory-18) and depression (Beck Depression Inventory-2).

RESULTS

Both patients with AN and BN exercised significantly more hours per week and showed significantly higher CE than HC; no differences were found between patients with AN and BN. Patients with EDs and HC also partly varied in motives for exercise. Specific motives were enjoyment, challenge, recognition and weight management in patients with EDs in contrast to ill-health avoidance and affiliation in HC. Patients with AN and BN only differed in regard to exercise for appearance reasons in which patients with BN scored higher. The most relevant predictor of CE across groups was exercise for weight and shape reasons.

CONCLUSIONS

Exercise behaviours and motives differ between patients with EDs and HC. CE was pronounced in both patients with AN and BN. Therefore, future research should focus not only on CE in patients with AN, but also on CE in patients with BN. Similarities in CE in patients with AN and BN support a transdiagnostic approach during the development of interventions specifically targeting CE in patients with EDs.

Is abstinence really the best option? Exploring the role of exercise in the treatment and management of eating disorders

Exercise prescription is suggested to help manage exercise abuse and improve overall eating disorder (ED) prognosis. This study explored emerging perceptions of ED health professionals concerning the role of exercise as a supportive treatment for EDs. Semi-structured interviews were conducted with international health professionals (n=13) with expertise in ED treatment. Verbatim transcripts were analyzed through thematic analysis. Four themes were revealed and titled 1) understanding the current state; 2) gaining perspectives; 3) barriers and benefits; 4) one size does not fit all. Within these themes, participants described the current state of exercise in ED treatment and suggested there exists a gap in research knowledge and practice. Participants also identified the implications of incorporating exercise into treatment and how an exercise protocol may be designed. Results enhance the understanding of the role of exercise in ED treatment and how it may further benefit individuals with EDs.

Compulsive exercise in eating disorders: proposal for a definition and a clinical assessment

BACKGROUND

Compulsive exercise has been recognized as a highly prevalent symptom in eating disorders (ED) for over 100 years and is associated with poor short-term and long-term treatment outcome. Progress in understanding and treatment of compulsive exercise will remain limited as long as no consensus framework for definition and assessment of compulsive exercise exists, as results cannot be compared across clinical studies.Based on existing literature, it was our aim to propose a transdiagnostic definition and a clinical assessment for compulsive exercise, that can be applied to adolescent and adult patients with ED.

METHOD

During a series of meetings of experienced clinicians at a highly specialized hospital for eating disorders, we elaborated a transdiagnostic definition of compulsive exercise in ED. Additionally, we derived a clinical interview for the assessment of compulsive exercise and its different subtypes.

RESULTS

The core criterion when defining and assessing compulsive exercise is a pathologically increased exercise pattern characterized by 1) excessive exercise that a patient feels driven to perform in response to an obsession or according to rules that must be applied rigidly, and 2) exercise that is aimed at preventing or reducing distress or at preventing some dreaded consequence. A second necessary criterion is the physical or psychological burden caused by compulsive exercise, i.e., that it is time-consuming, significantly interferes with the patient's daily routine, occupational functioning or social relationships or is continued despite medical injury, illness, or lack of enjoyment. Insight that compulsive exercise is excessive or unreasonable was added as an optional criterion.Compulsive exercise manifests itself in three different subtypes: 1) vigorous exercise, 2) marked increase in daily movement, or 3) motor restlessness.The above criteria must be met during the past 6 months, together with one of the three subtypes of compulsive exercise.

CONCLUSIONS

The proposed criteria aim to foster the discussion around definition and assessment of compulsive exercise with the goal of reaching an international consensus in the near future.Providing a consistent framework for researchers and clinicians would considerably advance understanding and treatment of compulsive exercise in ED patients.

An investigation of the process of change in psychopathology and exercise during inpatient treatment for adults with longstanding eating disorders

BACKGROUND

Excessive exercise is recognized as a predictor of poor outcome in eating disorders. However, little is known about how excessive exercise might affect the treatment process. The aim of this study was to describe process of weekly changes in eating disorder psychopathology, general psychopathology and exercise, and the possible interactive effects of excessive exercise on these changes during inpatient treatment of longstanding eating disorders.

METHODS

Eighty-four patients meeting the DSM-IV criteria for Anorexia Nervosa, Bulimia Nervosa, or Eating Disorders Not Otherwise Specified received inpatient cognitive-behavioural therapy including, physical activity and nutritional counselling treatment over 12 weeks. Excessive exercise was defined as having ≥6 episodes of driven exercise during week 1 of treatment. Excessive exercisers received one additional session of individual counseling with the clinical exercise physiologist. The study used repeated measurements during treatment and collected measures of eating disorders: psychopathology (EDE-Q), general psychopathology (SCL-5), and frequencies of exercise and body mass index (BMI). Statistical analysis was performed using repeated measures ANOVA.

RESULTS

Both eating disorders and general psychopathology were reduced from admission to discharge in excessive exercisers and non-exercisers. There was an overall interaction effect between time (week) and excessive exercise for the process of exercise and eating disorders psychopathology reduction. This interaction effect was also found in week 10 vs 11 regarding general psychopathology. The excessive exercisers showed steep reduction at first, followed by a smaller increase towards the end of treatment in both eating disorder and general psychopathology; this pattern was not found among the non-exercisers.

CONCLUSION

The process of change in exercise and psychopathology during inpatient treatment of longstanding eating disorders differs across excessive and non-excessive exercisers. Although excessive exercisers were given special attention for their exercise cognition and behavior during treatment, it is apparent that this part of treatment must be further developed.

Treatment effects on compulsive exercise and physical activity in eating disorders

BACKGROUND

Dysfunctional thoughts- and use of physical activity (PA) are core symptoms of the eating disorders (ED) bulimia nervosa (BN) and binge eating disorder (BED). The compulsive desire for PA complicates a favourable treatment outcome; hence, regular, adapted PA led by personnel with competence in exercise science is rarely part of treatment of BN and BED. The present study compared cognitive behaviour therapy (CBT) with a new treatment combining physical exercise and dietary therapy (PED-t) with respect to the short- and long-term changes in the level of compulsive exercise and actual level of PA in women with BN or BED.

METHODS

We enrolled 187 women with BN or BED, aged 18-40 years, with BMI 17.5-35, in an outpatient randomised controlled therapy trial. Participants were randomised to PED-t or CBT, while waitlist participants served as a control group during the treatment period. The treatment covered 16 weeks, with 6- and 12 months follow-up, and outcomes included self-reported compulsive exercise (CE) and objectively measured PA, analysed by linear mixed regression models.

RESULTS

Both CBT and PED-t reduced CE from baseline (P < 0.01, Hedges g ~ 0.4), but with no difference to control group. Compared to baseline, only PED-t significantly reduced the number of patients who scored above cut-off rating for CE, but with no between-group differences. The proportion of participants complying with the official recommendation for PA neither changed following treatment, nor emerged different between the treatment arms.

CONCLUSION

Both therapies resulted in significant improvements in compulsive exercise, a change not found in the control group, however there were no between-group differences. The findings are tempered by the low statistical power due to a small control group size. The number of participants complying with the recommendation for PA were stable throughout the study, and no change in total PA was found. Presence and intensity of CE decline with treatment, but a need to increase PA towards healthy levels remains unsolved.

Exercise in Eating Disorders Treatment: Systematic Review and Proposal of Guidelines

INTRODUCTION

Although exercise is an effective intervention for many psychological health issues, it has often been overlooked as a potential adjunct to eating disorder (ED) treatment. Thus, our objective was to summarize the literature by synthesizing themes identified in clinical studies and explicit guidelines or recommendations for the use or management of exercise in ED interventions into a proposed set of guidelines for the use of exercise in ED treatment.

METHODS

A literature search in exercise science, health psychology, and the ED literature was conducted. The focus was to obtain articles that reported on therapeutic effects and/or guidelines for the therapeutic use of exercise in individuals with ED.

RESULTS

Our review identified 11 core themes describing techniques that have been successful in using exercise therapeutically in ED treatment. These 11 guidelines are as follows: employ a team of relevant experts, monitor medical status, screen for exercise-related psychopathology, create a written contract of how therapeutic exercise will be used, include a psychoeducational component, focus on positive reinforcement, create a graded exercise program, begin with mild-intensity exercise, tailor the mode of exercise to the needs of the individual, include a nutritional component, and debrief after exercise sessions.

CONCLUSION

Our review identifies specific guidelines that may enhance ED treatment outcomes. It is the first to summarize divergent literature and synthesizes previous successes that may guide the use of therapeutic exercise in some, but not all ED patients. This review provides a practical set of guidelines for the clinical management and therapeutic use of exercise in ED treatment by focusing on empowering individuals with exercise as a tool for healthy living.

Co-Rumination of Fat Talk and Weight Control Practices: An Application of Confirmation Theory

Grounded in confirmation theory, the current research sought to explore the relationship between co-rumination of fat talk and weight control practices (i.e., binging and purging, exercising, and healthy eating behaviors), with a particular interest in whether perceptions of friends' responses during these interactions exacerbate or mitigate this relationship. Female friendship dyads completed online questionnaires at three time points across 2 weeks. Multilevel modeling analyses revealed that (a) co-rumination was positively associated with binging and purging and exercising, (b) women who perceived their friends as accepting reported less binging and purging, more exercising, and more healthy eating behaviors,

Frequent exercise: A healthy habit or a behavioral addiction?

It is well known that regular physical activity helps improve overall health and fitness and reduces the risk of many chronic diseases. However, excessive exercise might be harmful. Exercise addiction (EA) is a pattern of uncontrolled exercise that involves a craving for overwhelming exercise with addictive attributes. So far, little is known about this unique behavioral addiction. The aim of the current study is to introduce the diagnosis and assessment of EA, and to summarize several developing theoretical models. Eating disorders, body image disorder, low self-esteem, and high narcissism are related to high risk of EA. The paper also discusses the distinction between EA and highly involved physical activity.

Dimensions of Compulsive Exercise across Eating Disorder Diagnostic Subtypes and the Validation of the Spanish Version of the Compulsive Exercise Test

Objectives: Compulsive exercise in eating disorders has been traditionally considered as a behavior that serves the purpose of weight/shape control. More recently, it has been postulated that there may be other factors that drive the compulsive need to exercise. This has led to the development of the Compulsive Exercise Test (CET); a self-reported questionnaire that aims to explore the cognitive-behavioral underpinnings of compulsive exercise from a multi-faceted perspective. The objectives of this study were threefold: (1) to validate the Spanish version of the CET; (2) to compare eating disorder diagnostic subtypes and a healthy control group in terms of the factors that drive compulsive exercise as defined by the CET; (3) to explore how the dimensions evaluated in the CET are associated with eating disorder symptoms and general psychopathology.

Methods: The CET was administered to a total of 157 patients with an eating disorder [40 anorexia nervosa, 56 bulimia nervosa (BN), and 61 eating disorder not-otherwise-specified (EDNOS)] and 128 healthy weight/eating controls. Patients were assessed via a semi-structured interview to reach a DSM-IV-TR diagnosis. Additionally, all participants completed the Symptom Checklist-90-Revised (SCL-90R) and the Eating Disorders Inventory-2 (EDI-2).

Results: Confirmatory factor analysis demonstrated adequate goodness-of-fit to the original five-factor model of the CET. BN and EDNOS patients scored higher in the avoidance and rule-driven behavior, weight control, and total CET scales in comparison to the healthy controls, and higher across all scales apart from the exercise rigidity scale compared to the anorexia nervosa patients. Mean scores of the anorexia nervosa patients did not differ to those of the control participants, except for the mood improvement scale where the anorexia nervosa patients obtained a lower mean score. Mean scores between the BN and EDNOS patients were equivalent. The CET scales avoidance and rule-driven behavior, weight of control and total CET scores were positively correlated with the clinical assessment measures of the SCL-90R and EDI-2.

Conclusion: Compulsive exercise is a multidimensional construct and the factors driving compulsive exercise differ according to the eating disorder diagnostic subtype. This should be taken into account when addressing compulsive exercise during the treatment of eating disorders.

Behavioral and psychological aspects of exercise across stages of eating disorder recovery

This study examined the relationship between behavioral and psychological aspects of exercise and eating disorder recovery. Participants were categorized as having an eating disorder (n = 53), partially recovered (n = 15), fully recovered (n = 20), or non-eating disorder controls (n = 67). Groups did not differ significantly in time spent exercising, but did differ in exercise intensity, guilt-related exercise, obsessive exercise cognitions, and appearance/weight management and stress/mood management motivations for exercise. Results support the importance of measuring psychological aspects of exercise in particular across the course of an eating disorder.

Exercise and physical therapy help restore body and self in clients with severe anorexia nervosa

Exercise in the context of anorexia nervosa is a multifaceted endeavour surrounded by controversy and uncertainty. A broader comprehension of this poorly understood phenomenon is required. Informed by the findings of a body examination of six individuals with anorexia nervosa, as well as exercise science, phenomenology and neurocognition, the purpose of this article is to elaborate on the potential role of exercise and physical therapy in the treatment of anorexia nervosa. The findings of the body assessment include constriction of posture, muscles and pattern of breathing. These bodily restraints are not necessarily merely associated with high levels of exercise, they may also reflect psychological strain accompanying the illness. The restricted breathing in particular is assumed to be associated with difficult thoughts and suppressed feelings. Based on the results of the body examination, as well as medical and psychological considerations accompanying the illness, it is suggested that interventions should focus on improving postural stability and restoring related muscular function. Integral to engaging in these activities, the potential to integrate proprioceptive information in this process may generate a more coherent experience of the body, as well as of the self, in these clients. Accordingly, constrictions of the body may have a vital role in constraining the experience of the self. As such, addressing bodily restraints in these clients may facilitate the experience of being the subject causing and controlling the movements. This is in marked contrast to clients' previous exercise experiences, which were associated with compulsion, rigidity and the absence of coherence and control.

The Physical Self-Attribute Questionnaire: Development and Initial Validation

The Physical Self-attribute Questionnaire was developed for use in conjunction with the Physical Self-perception Profile to model cognitive facets of perceived competence, certainty, importance, and discrepancy from ideal to each of the physical subdomains measured by the latter (Strength, Attractive Body, Condition, and Sport). To this end, two studies were conducted. Study 1 examined the factor structure, test-retest reliability, and validity of the questionnaire in a sample of 154 (28 men, 126 women) undergraduate health students. Reliability and validity were acceptable, and confirmatory factor analysis indicated good fit for a four-factor solution. In Study 2, the reliability, validity, and factor structure was again confirmed in a sample of 120 (83 men, 37 women) undergraduate students recruited from exercise classes. Results of these two studies suggest that the Physical Self-attribute Questionnaire is a viable tool to measure the underlying cognitive facets of subdomain-specific physical self-esteem.

Impact of female adult eating disorder inpatients' attitudes to compulsive exercise on outcome at discharge and follow-up

BACKGROUND

The link between compulsive exercise and eating disorders is well known, but research with clinical samples has been limited. The purpose of the study was to investigate changes in attitudes towards compulsive exercise and its impact on outcome at follow-up in female adult hospitalised patients with eating disorders.

METHODS

The sample consisted of 78 patients: Diagnostic distribution: anorexia nervosa 59 % (n = 46), approximately 22 % (n = 16) in bulimia nervosa, and Eating Disorder not Otherwise Specified respectively. The average follow-up period was 26 months (SD =15 months). Compulsive exercise was measured by the Exercise and Eating Disorder (EED) questionnaire. Other measures were the Eating Disorder Inventory (EDI-2), Body Attitude Test (BAT), Symptom Checklist (SCL-90), Inventory of Interpersonal Problems (IIP 64), Beck Depression Inventory (BDI), and body mass index (BMI). Outcome measures were EDI-2 and BMI (patients with admission BMI ≤ 18.5). Paired sample t-tests and mixed model regression analysis were conducted to investigate changes in compulsive exercise and predictors of outcome respectively.

RESULTS

All measures revealed significant improvements (p < .01 - p < .001) from admission to follow-up. EED scores significantly predicted changes in EDI-2 scores and BMI (p < .01 and p < .001 respectively). Other significant predictors were BAT, SCL-90, IIP-64, BMI (p < .01-.001) (EDI-2 as outcome measure), and BAT and BDI (p < .001) (BMI as outcome measure).

CONCLUSIONS

The results demonstrated significant improvements in attitudes towards compulsive exercise during treatment and follow-up. The change in compulsive exercise scores predicted the longer-term course of eating disorder symptoms and BMI.

'Feelings stronger than reason': conflicting experiences of exercise in women with anorexia nervosa

BACKGROUND

Individuals with anorexia nervosa frequently feel ambivalent about treatment and weight restoration, and drop out and relapse rates in treatment are high. Increased insight into the function of the eating disorder is considered essential for achieving long-lasting, meaningful change. However, research investigating the functions of anorexia nervosa tends to focus on the role of the disease per se. Distinctions are rarely made across features. In particular, the subjective experience, understanding and sense making of the engagement in compulsive exercise in individuals with anorexia nervosa has received little attention. By using a qualitative methodological approach, this paper aims to expand on prior findings by examining how patients with anorexia nervosa understand and make sense of the experience of exercise in the context of their lives and treatment programme.

METHODS

Semi-structured interviews were conducted with six females, four of whom were former athletes. Transcripts were subjected to interpretative phenomenological analysis (IPA).

RESULTS

Two overarching themes emerged in the analysis of the larger study of which this paper is a part; 'paradoxical functions of exercise' and 'diverging experiences of exercise'. Diverging experiences of exercise is the focus of this paper. Firstly, in spite of being severely underweight and suffering from exhaustion, as well as having a clear awareness of the associated negative health effects, participants were engaged in a continuous cycle of rigorous and excessive exercise, which consumed extensive amounts of time and energy. Secondly, the results demonstrate how exercise routines negatively control and interfere with the participants' involvement in the social world. Thirdly, the manner in which participants speak about their exercise reveals their wording to be characterized by efforts to downplay the extent of their actual immersion in exercise. Issues of control and ambivalence about treatment and recovery can be considered potential triggers for the participants' engagement with exercise. Implicit meanings are elaborated upon and discussed in relation to existing literature.

CONCLUSIONS

The material provides increased insight into the multi-layered meanings of exercise for individuals with anorexia nervosa. It also suggests alternatives to current ways of understanding and approaching exercise that may enable this issue to be addressed in a more meaningful way in therapy. Qualitative approaches can make a valuable contribution to furthering such understanding.
