A small group aerobic exercise programme that reduces body weight is feasible in adults with severe chronic schizophrenia: a pilot study

Aerobic and Postural Strength Exercise Benefits in People with Schizophrenia

BACKGROUND

This study aimed to evaluate the effect of two different types of physical intervention on sedentary behavior and clinical changes in people with schizophrenia.

METHOD

This is a clinical trial including people with schizophrenia in regular outpatient care who realized a 3-month exercise protocol and were separated into two groups: aerobic physical intervention (API) and postural physical intervention (PPI). All participants performed an assessment of (a) functional capacity through a 6 min walk test (6MWT), (b) flexibility using Well's bench, (c) disease severity using the Brief Psychiatric Rating Scale (BPRS), (d) quality of life using the SF-36 Questionnaire and (e) physical activity using the Simple Physical Activity Questionnaire (SIMPAQ).

RESULTS

Thirty-eight patients with schizophrenia completed the intervention (24 patients in API and 14 patients in PPI). Regarding sedentary behavior, there was an improvement in the API group in the time exercising and in the PPI group concerning time in bed, time walking and exercising. Regarding quality of life, there was an improvement in the API group (functional capacity) and in the PPI group, there was an improvement in physical limitation, pain and emotional limitations. In the API group, there was an improvement in BMI (body mass index), diastolic blood pressure and systolic blood pressure. Functional capacity was improved only in the PPI group. There was no change in flexibility and disease severity.

CONCLUSIONS

The study demonstrated a change response in the physical and mental aspects in people with schizophrenia after a change in sedentary behavior.

The Transtheoretical Model based psychoeducation's effect on healthy lifestyle behaviours in schizophrenia: A randomized controlled trial

OBJECTIVE

The study was conducted with the pretest-posttest randomized controlled trial design to detect the psychoeducation's effect, based on the Transtheoretical Model, on the healthy lifestyle behaviours of individuals with schizophrenia.

METHODS

The data were collected from 82 participants, as 41 intervention and 41 control. The data were collected via personal information form, behavioural change stage diagnosis form and healthy lifestyle scale II. 6-week psychoeducation, consisting of 6 modules, based on the Transtheoretical Model, was applied to the intervention group. No interventions were applied to the control group. Pretests and posttests were applied to both groups.

RESULTS

When the healthy lifestyle scale II of intervention and control groups and final test results arranged according to ANCOVA analysis are compared, average final test results were meaningfully positive for the intervention group with taking control of the pretest and other covariants. When the pretest-posttest results in terms of behavioural change of the intervention group are evaluated; a meaningful difference among nutrition, physical exercises, spiritual self-improvement and stress management, which all are the stages of behavioural change, was detected.

CONCLUSION

It was determined that psychoeducation on a healthy lifestyle, based on the Transtheoretical Model in an individual with schizophrenia affected physical exercises, spiritual self-improvement and interpersonal relationships sub-dimension in medium level, and had a drastic influence on health responsibility, nutrition, stress management sub-dimensions and all healthy lifestyle behaviours. Progress in behavioural change stages was detected.

Systematic review of physical activity interventions assessing physical and mental health outcomes on patients with severe mental illness (SMI) within secure forensic settings

WHAT IS KNOWN ON THE SUBJECT?: Individuals with a severe mental illness (SMI) are less physically active and have a lower life expectancy than the general population due to increased risks of cardiometabolic diseases (obesity, diabetes and respiratory diseases) and other health risks. Physical activity has been used as an adjunct therapy for individuals with SMI yielding improvements in cognitive functioning, quality of life and a reduction in psychiatric symptoms. Individuals with SMI residing within a secure forensic setting have reduced physical activity opportunities, possibly due to a number of factors including low motivation and restricted access to exercise facilities combined with a lack of knowledge and/or confidence in staff members to assist in physical activity programmes. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: This review demonstrates that little is known around the effects of physical activity for people with SMI who reside in secure forensic settings, with little to no long-term effects reported. Physical activity interventions have shown some positive results through decreasing weight and waist circumference as well as a reduction in negative symptom scores in an exercise group compared with the "no treatment" control group post-intervention. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Service users' reluctance to engage in physical activity may be overcome by improving staff commitment, creating a motivational atmosphere and promoting service user decision making.

ABSTRACT

INTRODUCTION: Participating in physical activity has many benefits, yet those with severe mental illness (SMI) living in forensic settings are less likely to be active, and more likely to experience ill-health. The aim of this study was to systematically review the effectiveness of physical activity programmes on mental and physical health and specifically on reducing symptoms of SMI in forensic settings.

METHOD

A systematic search of six databases was conducted, in addition to a grey literature search. Studies were included if they had participants with SMI; were based in a forensic setting; involved a physical activity programme and reported physical and mental health outcomes.

RESULTS

A total of 112 participants were included in four studies. One study showed a significant improvement in negative symptom scores in the exercise group compared with a treatment as usual group. Two studies reported improvements in psychiatric symptoms with no significant difference between groups; however, statistically significant changes in weight and waist circumference were evident (p < .001). No adverse effects were reported.

CONCLUSION

Only a small number of studies were included and of limited design and quality, with no follow-up assessments; therefore, more research is needed to determine the true effects of physical activity for improving SMI symptoms in a forensic setting. This review highlights the need for further studies exploring the barriers and facilitators of physical activity in secure forensic settings. Studies are required that include a more thorough research design. Furthermore, interventions if designed with patients and caring staff in mind may lead to lowered psychiatric symptoms and increased physical health benefits for all in forensic settings.

Physical Activity, Positive and Negative Symptoms of Psychosis, and General Psychopathology among People with Psychotic Disorders: A Meta-Analysis

Objective: Existing reviews provided evidence for the associations between higher physical activity (PA) and lower negative symptoms of psychosis among people with schizophrenia. This meta-analysis goes beyond existing syntheses and investigates associations between PA, positive and negative symptoms of psychosis, as well as symptoms of general psychopathology (referring mostly to cognitive functioning) among people with schizophrenia, but also other psychotic disorders. The moderating roles of the type of diagnosis and the type of exercise intervention were explored. Methods: The study was registered with PROSPERO (CRD42018118236). Six electronic databases were searched; n = 27 experimental and observational studies were included, and psychotic symptoms-related data were recorded in one direction (higher values indicate better mental health and lower symptomatology). Results: Higher levels of PA (or participating in PA interventions) were associated with better mental health, that is, lower levels of positive symptoms (all studies: r = 0.170; experimental studies: SMD = 0.677), negative symptoms (all studies: r = 0.214; experimental studies: SMD = 0.838), and general psychopathology (all studies: r = 0.451; experimental studies: SMD = 1.511). The type of diagnosis (schizophrenia vs. other psychotic disorders) did not moderate these associations. Conclusions: We found a consistent pattern of associations between higher levels of PA and lower positive, negative, and general psychopathology symptoms in people with schizophrenia and those with other psychotic disorders.

Effects of Aerobic, Resistance, and Combined Exercise Training on Psychiatric Symptom Severity and Related Health Measures in Adults Living With Schizophrenia: A Systematic Review and Meta-Analysis

Previous research has demonstrated the efficacy, effectiveness, and safety of exercise training in persons living with schizophrenia. However, the optimal exercise training program remains unclear. The aim of this paper was to conduct a systematic review and meta-analysis of the effects of aerobic, resistance, and combined aerobic and resistance training on health-related physical fitness and positive and negative symptoms in persons living with schizophrenia. Six electronic databases were searched systematically from their inception to December 2020 [MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, SPORTDiscus, and Cumulative Index to Nursing and Allied Health Literature (CINAHL)] to identify literature examining the effects of exercise training on psychiatric symptoms and health-related physical fitness indicators in persons living with schizophrenia. A total of 22 studies (n = 913) were included in this review, and 12 studies (n = 554) included within the meta-analysis reported the effects of exercise training (aerobic, resistance, and combined aerobic and resistance) in persons living with schizophrenia. Aerobic training had a significant decrease on Positive and Negative Syndrome Scale (PANSS) negative scores (ES -2.28, 95% CI -3.57 to -1.00; p = 0.0005) and PANSS general scores (ES -2.51, 95% CI -3.47 to -1.55; p < 0.00001). Resistance training did not lead to significant effects on PANSS total scores. Combined aerobic and resistance training did not lead to significant changes in body mass index, PANSS positive scores, or PANSS total scores. However, grouping together the results from all exercise training modalities (including aerobic training, resistance training, and combined aerobic and resistance training) revealed significant effects on body mass index (ES 1.86, 95% CI 0.84 to 2.88; p = 0.0003), maximal/peak oxygen consumption (ES 2.54, 95% CI 1.47 to 3.62; p = < 0.00001), body weight (ES 6.58, 95% CI 2.94 to 10.22; p = 0.0004), PANSS negative scores (ES -1.90, 95% CI -2.70 to -1.10; p < 0.00001), and Scale for the Assessment of Negative Symptoms (SANS) total (ES -14.90, 95% CI -22.07 to -7.74; p < 0.0001). Collectively, these findings support the importance of exercise participation (aerobic and resistance training) in persons living with schizophrenia.

Study protocol for a pilot high-intensity interval training intervention in inpatient mental health settings: a two-part study using a randomised controlled trial and naturalistic study design

BACKGROUND

Severe mental illnesses (SMI), including schizophrenia spectrum disorder, bipolar disorder and major depressive disorder, are associated with physical health comorbidities and premature mortality. Physical activity and structured exercise have a beneficial impact on cardiometabolic risk and ameliorate mental health symptomology and cognition. This protocol describes a feasibility study for a high-intensity interval training (HIIT) intervention among inpatients with SMI, to improve their physical and mental health.

METHODS

The feasibility study follows a two-part design owing to COVID-19-related adaptations to project design: (a) a non-blinded randomised controlled trial (RCT) of 12 weeks of bicycle-based HIIT, delivered twice weekly in a face-to-face, one-to-one setting, compared to treatment as usual (TAU) and (b) a naturalistic study of inpatient HIIT; eligible participants will be invited to two sessions of HIIT per week, delivered by the research team remotely or in person. Additionally, participants in the naturalistic study may use the bike to conduct self-directed sessions of their chosen length and intensity. We will measure the feasibility and acceptability of the HIIT intervention as primary outcomes, alongside secondary and tertiary outcomes evaluating the physical, mental and cognitive effects of HIIT. The study aims to recruit 40 patients to the RCT and 6-8 patients to the naturalistic design.

DISCUSSION

Exercise is a modifiable lifestyle barrier that can reverse cardiometabolic disease risk. If HIIT is found to be feasible and acceptable in inpatients with SMI, there would be scope for large-scale work to evaluate the clinical, cost and implementation effectiveness of HIIT in inpatient mental health settings.

Effects of Exercise on Resilience, Insight and Functionality in Patients with Chronic Schizophrenia in a Psychiatric Nursing Home Setting: A Randomized Controlled Trial

To our knowledge, there are no studies on the effects of exercise in patients with severe schizophrenia-related disability or in nursing home settings. Again, the literature search on the influence of exercise on insight and resilience gives no results except mind-body exercises. The aim of this study was to investigate the effects of exercise on psychotic symptoms, depression, functionality, insight and resilience in patients with severe schizophrenia-related disability living in nursing home setting. Thirty-nine patients with schizophrenia were recruited. Exercise group with 20 patients who continued resistance exercise for 60 min, 2 days a week, for 3 months; and treatment as usual (TAU) group with 19 patients. All patients were administered Scale for the Assessment of Positive Symptoms, Scale for the Assessment of Negative Symptoms (SANS), Calgary Depression Scale for Schizophrenia (CDSS), Schedule for Assessment of Insight (SAI), Functional Remission of General Schizophrenia Scale (FROGS), Resilience Scale for Adults (RSA) at baseline and 3 months after. There were no significant differences between the groups for baseline and third month scores. In both groups significant decrease in SANS scores, significant increase in scores of FROGS total and social functioning, daily life skills subscale and RSA perception of the self were observed. In exercise group, significant decrease in CDSS scores, and significant increase in SAI awareness of illness, FROGS health and treatment, occupational functioning scores were found. Exercise combined with TAU may be effective in increasing awareness of illness and alleviating depression in chronic schizophrenia.

Effect of high-intensity interval training on cardiorespiratory fitness, physical activity and body composition in people with schizophrenia: a randomized controlled trial

BACKGROUND

Exercise may improve cardiorespiratory fitness in people with schizophrenia, however, possible condition-specific cardiorespiratory disadvantages, a scarcity of methodologically sound studies, and conflicting results raise questions about the effect of exercise on maximal oxygen uptake (VO2max) in this group. The primary aim of this study, therefore, was to investigate the effect of high-intensity interval training on VO2max in people with schizophrenia. Second, we sought to determine whether the intervention would have an effect on general physical activity (PA) level and body composition.

METHODS

Eighty-two patients with schizophrenia were randomly assigned to supervised high-intensity interval training or computer gaming skills training, performed twice a week for 12 weeks. Oxygen uptake was measured directly, during a maximum exercise session on a treadmill. PA level were assessed using ActiGraph accelerometer, and body composition was assessed by bioelectrical impedance. Differences between groups were assessed by analysis of variance using a univariate general linear model.

RESULTS

There were no significant differences between the groups on any of the cardiorespiratory variables neither at baseline nor after the program. There were also no significant within-group differences in any of the cardiorespiratory fitness variables between the baseline and post-program time points, despite that 61% of the participants performing high-intensity interval training showed a significant increase in workload on the treadmill. However, 47% of the participants in the high-intensity interval training group had a ≥ 5% increase in VO2max. Participants supervised by mental health care providers with PA competence (e.g. rehabilitation center staff, sport scientist, physical trainer) had a much larger increase in VO2max compared to participants supervised by mental health workers without such competence, and when adding PA competence to the model, the intervention group increased VO2max significantly compared to the comparison group. The intervention had no significant effect on PA level or body composition.

CONCLUSIONS

The intervention did not improve VO2max, PA level or body composition but succeeded in increasing workload on the treadmill. With regard to VO2max, approximately half of the patients may be considered responders.

Designing a feasible exercise intervention in first-episode psychosis: Exercise quality, engagement and effect

First-episode psychosis (FEP) is the first presentation of a psychotic disorder that usually propagates during early adulthood. FEP represents an important early intervention point to attenuate the metabolic risks associated with psychosis and its treatment. Exercise has potential to improve metabolic and functional outcome, but engaging this population in regular exercise is typically difficult. Promoting enjoyment and attendance may improve participation. 22 men with FEP were randomised to a 12-week intervention of exercise training, or treatment as usual. Exercise was pre-standardised based on measures of heart rate to assess intensity. Symptoms of psychosis were assessed, alongside measures of quality of life, disability and habitual activity. The study observed 83% attendance at exercise sessions, with target intensity attained. There were clinically meaningful decreases in PANSS positive (17.31%) and general psychopathology (10.98%) scores and exercise was protective of negative score increase observed in the control group (13.89%). Assessment of disability declined after training (12.65%) compared with a 20.78% increase in controls. This study demonstrated that engagement of FEP patients in an intervention of high quality exercise was possible. Positive changes in psychopathology scores and disability show that the benefits of regular exercise are achievable with a potential positive impact on clinical presentation.

Nonpharmacological Interventions for the Treatment of Cardiometabolic Risk Factors in People With Schizophrenia-A Systematic Review

Background: People suffering from schizophrenia are notably vulnerable to cardiometabolic risk factors (CMRF), such as obesity, high blood pressure, hyperglycemia and insulin resistance, high serum triglycerides, and low serum high-density lipoprotein (HDL), which are related to increased mortality and decreased quality of life. The increased risk of "metabolic syndrome" (MS) is related to low physical activity, an unhealthy diet, and side effects of antipsychotic drugs. Nonpharmacological interventions seem to be important in the prevention and therapy of MS. Aim: This paper provides an overview of published studies and a critical analysis of pilot programs involving nonpharmacological measures aimed at prevention and treatment of CMRF in patients with schizophrenia. Material and Method: We searched the PubMed, PsycARTICLES, and Cochrane Library databases to identify clinical trials. We included full-text studies that met the following criteria: age > 18 years, a diagnosis of schizophrenia or schizoaffective disorder, and monitored parameters associated with MS. Results: All 1,555 references were evaluated for inclusion in the review, and 20 met the inclusion criteria. Nonpharmacological interventions led to improvement in physical health and showed a promising potential for implementation in treatment programs dedicated to this particular group of patients. However, a critical analysis revealed limitations, which have implications for the direction of future research. Conclusions: Patients suffering from schizophrenia can benefit from nonpharmacological interventions aimed at counteracting CMRF, improving either metabolic parameters, cardiovascular fitness, or their health perception. Notwithstanding, to achieve long-term effects, future studies should comprise appropriate follow-up procedures.

Evaluating the Feasibility of a Pilot Exercise Intervention Implemented Within a Residential Rehabilitation Unit for People With Severe Mental Illness: GO HEART: (Group Occupational Health Exercise and Rehabilitation Treatment)

Purpose: People with severe mental illness are sedentary, have high cardio-metabolic risks and significantly reduced life expectancy. Despite considerable data regarding positive physical and mental health outcomes following exercise interventions, implementation and evaluation of real-world programs is lacking. The primary aim of this study was to assess the feasibility of an exercise intervention implemented by exercise physiology (EP) students within a residential rehabilitation unit for residents with severe mental illness, together with assessment of a range of secondary physical and mental health outcomes pre- and post- the intervention. Design: Single arm, prospective pilot study evaluating outcomes pre- and post- a 10 week intervention. Method: Inactive people with severe mental illness participated in a mixed aerobic and resistance exercise intervention, three times per week for 10 weeks. Data was obtained from a sample of 16 residents with severe mental illness; primary diagnosis schizophrenia (n = 12). Primary outcomes were feasibility as assessed using recruitment, retention and participation rates, as well as reasons for withdrawal and amount of exercise achieved. Secondary outcomes included: functional exercise capacity was measured by the 6-min walk test; metabolic data obtained from anthropometric measurements; blood pressure; fasting cholesterol and blood sugar levels; and physical activity levels and mental health as assessed by self- administered questionnaires measured before and after the intervention. Results: Broad level acceptance of the program: high recruitment (81%), retention (77%), and participation (78%) rates were observed. Promising improvements in functional exercise capacity, volume of exercise, and negative symptoms was demonstrated in those who completed. Conclusions: Exercise interventions delivered by EP students in a residential rehabilitation setting for people with SMI are feasible; group setting, supervision and choice for engagement are important considerations. Evaluation of longitudinal, multi site studies, with the addition of dietary interventions within residential rehabilitation units are warranted. Addressing cost feasibility and cost effectiveness of such programs is recommended. The trial was registered with the Australian New Zealand Clinical Trials Registry (ANZCTR) number, Unique Identifier: ACTRN 12618000478213, http://www.anzctr.org.au Universal trial number (UTN) - U1111-1211-4009.

Effects of Aerobic Exercise on Metabolic Syndrome, Cardiorespiratory Fitness, and Symptoms in Schizophrenia Include Decreased Mortality

Schizophrenia is a severe psychiatric disorder with a lifetime prevalence of about 1%. People with schizophrenia have a 4-fold higher prevalence of metabolic syndrome than the general population, mainly because of antipsychotic treatment but perhaps also because of decreased physical activity. Metabolic syndrome is a risk factor for cardiovascular diseases, and the risk of these diseases is 2- to 3-fold higher in schizophrenia patients than in the general population. The suicide risk is also higher in schizophrenia, partly as a result of depression, positive, and cognitive symptoms of the disease. The higher suicide rate and higher rate of cardiac mortality, a consequence of the increased prevalance of cardiovascular diseases, contribute to the reduced life expectancy, which is up to 20 years lower than in the general population. Regular physical activity, especially in combination with psychosocial and dietary interventions, can improve parameters of the metabolic syndrome and cardiorespiratory fitness. Furthermore, aerobic exercise has been shown to improve cognitive deficits; total symptom severity, including positive and negative symptoms; depression; quality of life; and global functioning. High-intensity interval endurance training is a feasible and effective way to improve cardiorespiratory fitness and metabolic parameters and has been established as such in somatic disorders. It may have more beneficial effects on the metabolic state than more moderate and continuous endurance training methods, but to date it has not been investigated in schizophrenia patients in controlled, randomized trials. This review discusses physical training methods to improve cardiorespiratory fitness and reduce metabolic syndrome risk factors and symptoms in schizophrenia patients. The results of studies and future high-quality clinical trials are expected to lead to the development of an evidence-based physical training program for patients that includes practical recommendations, such as the optimal length and type of aerobic exercise programs and the ideal combination of exercise, psychoeducation, and individual weight management sessions.

Exercise Treatments for Psychosis: A Review

Schizophrenia is a devastating mental illness that has profound effects on a person's health and quality of life. Exercise represents a promising new treatment option that may supplement current psychosocial and pharmacological interventions for psychosis. A large body of work suggests that exercise can improve cardio-metabolic and health behavior and facilitate neurogenesis in areas of the brain that are notably impacted by psychosis. Recent efforts to incorporate exercise as either stand-alone or adjunctive treatment for individuals with schizophrenia range from yoga and light stretching to moderately intense walking, bike riding, or team sports. These interventions suggest that moderately intense exercise may be beneficial for improving both positive and negative symptomatology, cognition and functioning. Indeed, exercise may be beneficial for decreasing risk factors for a wide range of health problems often observed in patients with schizophrenia, including weight gain and metabolic syndrome as well as tobacco and substance use. Given the positive results from interventions in schizophrenia patients, there is an impetus for incorporating exercise in the early stages of the disorder. Notably, individuals at ultrahigh risk (UHR) for psychosis report more sedentary behavior and perceive less benefit from exercise; interventions prior to the onset of the disorder may be helpful for increasing health behaviors, perhaps delaying or preventing the onset of psychosis. Taken together, for individuals with psychosis, exercise may provide holistic benefits for the neural to the social impairments.

Examining methods, messengers and behavioural theories to disseminate physical activity information to individuals with a diagnosis of schizophrenia: a scoping review

BACKGROUND

Many individuals with a diagnosis of schizophrenia are not active and lack the necessary knowledge and confidence to become and stay active. To develop effective physical activity promotion interventions, it is necessary to identify credible messengers and effective methods to disseminate physical activity information to this population.

AIMS

The purpose of this scoping review was to identify and examine knowledge mobilization theories, messengers and methods used to disseminate physical activity information to individuals with a diagnosis of schizophrenia.

METHOD

This scoping review followed the methodological framework proposed by Arksey and O'Malley.

RESULTS

In total, 43 studies and 7 reviews identified multiple messengers and methods used to disseminate physical activity information to individuals with a diagnosis of schizophrenia, but few attempts to structure information theoretically. Findings do not point to which messengers or methods are most effective or which theories should be used to construct information interventions. Studies show that physical activity information should be provided in an individualised manner from staff who could easily connect with patients.

CONCLUSIONS

Few researchers have addressed the physical activity information needs of individuals with a diagnosis of schizophrenia. Researchers need to examine and implement effective knowledge mobilization strategies for this population.

Preliminary Effectiveness and Sustainability of Group Aerobic Exercise Program in Patients with Schizophrenia

The objective of this study was to examine the feasibility and sustained effect of a group aerobic exercise program in patients with schizophrenia. Twenty-four schizophrenic patients participated in a group-based individually tailored 90-minute outdoor cycling session per week for 3 months with intervention to enhance motivation. Physical health was evaluated by anthropometric measures, cardiorespiratory (CR) fitness, and blood tests. Mental health was assessed on self-esteem, interpersonal relationship, quality of life, and global function. Attrition rate for the exercise program was 8.3%. Exercise program significantly increased participant's self-esteem, positive relationship, global function, and quality of life. CR fitness significantly improved after 3 months. At the 9-month follow-up, 6 months after program completion, only in interpersonal relationship change the improved effects were maintained. These findings support the feasibility of group aerobic exercise program with high level of adherence and its long-term benefits in positive relationship change.

Endurance training in patients with schizophrenia and healthy controls: differences and similarities

The aims were to examine the feasibility of and adaptations to endurance training in persons diagnosed with schizophrenia and to address the question whether the principles and beneficial effects of endurance training established in the healthy population apply also to patients with schizophrenia. In this controlled interventional study, 22 patients with schizophrenia and 22 healthy controls performed a standardized aerobic endurance training on bicycle ergometers over 12 weeks. Another group of 21 patients with schizophrenia played table soccer. Endurance capacity was measured with incremental cycle ergometry before and after the intervention and 3 months later. A specific set of outcome parameters was defined. The training stimuli can be assumed to be similar in both endurance groups. Endurance capacity improved significantly in the endurance groups, but not in the table soccer group. Patients and healthy controls showed comparable adaptations to endurance training, as assessed by physical working capacity and maximal achieved power. Differences were found in changes of performance at a lactate concentration of 3 mmol/l. Endurance training was feasible and effective in both groups. The principles and types of training that are usually applied to healthy controls need to be verified in patients with schizophrenia. Nevertheless, patients benefited from endurance training in terms of improvement of endurance capacity and reduction in the baseline deficit in comparison with healthy controls. Therefore, endurance training should be implemented in future therapy programs. These programs need to pay special attention to the differences between patients with schizophrenia and healthy controls.

Exercise Improves Clinical Symptoms, Quality of Life, Global Functioning, and Depression in Schizophrenia: A Systematic Review and Meta-analysis

BACKGROUND

Physical exercise may be valuable for patients with schizophrenia spectrum disorders as it may have beneficial effect on clinical symptoms, quality of life and cognition.

METHODS

A systematic search was performed using PubMed (Medline), Embase, PsychInfo, and Cochrane Database of Systematic Reviews. Controlled and uncontrolled studies investigating the effect of any type of physical exercise interventions in schizophrenia spectrum disorders were included. Outcome measures were clinical symptoms, quality of life, global functioning, depression or cognition. Meta-analyses were performed using Comprehensive Meta-Analysis software. A random effects model was used to compute overall weighted effect sizes in Hedges' g.

RESULTS

Twenty-nine studies were included, examining 1109 patients. Exercise was superior to control conditions in improving total symptom severity (k = 14, n = 719: Hedges' g = .39, P < .001), positive (k = 15, n = 715: Hedges' g = .32, P < .01), negative (k = 18, n = 854: Hedges' g = .49, P < .001), and general (k = 10, n = 475: Hedges' g = .27, P < .05) symptoms, quality of life (k = 11, n = 770: Hedges' g = .55, P < .001), global functioning (k = 5, n = 342: Hedges' g = .32, P < .01), and depressive symptoms (k = 7, n = 337: Hedges' g = .71, P < .001). Yoga, specifically, improved the cognitive subdomain long-term memory (k = 2, n = 184: Hedges' g = .32, P < .05), while exercise in general or in any other form had no effect on cognition.

CONCLUSION

Physical exercise is a robust add-on treatment for improving clinical symptoms, quality of life, global functioning, and depressive symptoms in patients with schizophrenia. The effect on cognition is not demonstrated, but may be present for yoga.

Reliability and validity of 6MWT for outpatients with schizophrenia: A preliminary study

Although the 6-minute walk test (6MWT) has been widely used in patients with schizophrenia, there is a lack of scientific evidence about its reliability and validity in this population. The first goal of this study was to explore the test-retest reliability of the 6MWT and to identify the associated parameters that contribute to the variability of the distance walked during the 6MWT in outpatients with schizophrenia. The second goal was to assess the criterion validity of the 6MWT in men with schizophrenia. Fifty one outpatients with schizophrenia participated in the study. To test-retest reliability (men=39; women=12), participants performed the 6MWT twice within 3 days interval. To test criterion validity (men=13), peak oxygen uptake (VO2peak) was measured on a treadmill. For the associated parameters with the distance walked (n=51), medications use, smoking behavior, body and bone composition, and physical activity levels were analyzed. No significant differences between the means of the two 6MWTs were found. The intraclass correlation coefficient was 0.94 indicating good reliability. 6MWT correlated significantly with VO2peak (r=0.67) indicating criterion validity. Height, body fat mass, smoking behavior and minutes of PA/week were significantly associated with the 6MWT. Results suggest that 6MWT shows good reliability for individuals with schizophrenia and good validity for the small sample of male participants in this study.

Cancer screening, prevention, and treatment in people with mental illness

People with mental illness die decades earlier in the United States compared with the general population. Most of this disparity is related to preventable and treatable chronic conditions, with many studies finding cancer as the second leading cause of death. Individual lifestyle factors, such as smoking or limited adherence to treatment, are often cited as highly significant issues in shaping risk among persons with mental illness. However, many contextual or systems-level factors exacerbate these individual factors and may fundamentally drive health disparities among people with mental illness. The authors conducted an integrative review to summarize the empirical literature on cancer prevention, screening, and treatment for people with mental illness. Although multiple interventions are being developed and tested to address tobacco dependence and obesity in these populations, the evidence for effectiveness is quite limited, and essentially all prevention interventions focus at the individual level. This review identified only one published article describing evidence-based interventions to promote cancer screening and improve cancer treatment in people with mental illness. On the basis of a literature review and the experience and expertise of the authors, each section in this article concludes with suggestions at the individual, interpersonal, organizational, community, and policy levels that may improve cancer prevention, screening, and treatment in people with mental illness.

Using Smartphone Apps to Promote Psychiatric and Physical Well-Being

This pilot study tested the acceptability and usability of a prototype app designed to promote the physical well-being of adults with psychiatric disorders. The application under evaluation, WellWave, promoted walking as a physical exercise, and offered a variety of supportive non-physical activities, including confidential text-messaging with peer staff, and a digital library of readings and videos on recovery from psychiatric illness. Study participants engaged strongly in the app throughout the 4-week study, showing a 94 % mean daily usage rate, and a 73 % mean response rate across all electronic messages and prompts, which approximates the gold standard of 75 % for momentary ecological assessment studies. Seven of the ten study participants averaged two or more walks per week, beginning with 5-min walks and ending with walks lasting 20 min or longer. This responsiveness to the walking prompts, and the overall high rate of engagement in other app features, suggest that adults with psychiatric conditions would welcome and benefit from similar smartphone interventions that promote healthy behaviours in life domains other than exercise. Pilot study results also suggest that smartphone applications can be useful as research tools in the development and testing of theories and practical strategies for encouraging healthy lifestyles. Participants were prompted periodically to rate their own health quality, perceived control over their health, and stage-of-change in adopting a walking routine, and these electronic self-ratings showed acceptable concurrent and discriminant validity, with all participants reporting moderate to high motivation to exercise by the end of the study.

The value of social support to encourage people with schizophrenia to engage in physical activity: an international insight from specialist mental health physiotherapists

BACKGROUND

Research is needed to understand how mental health physiotherapists use social support when promoting physical activity.

AIMS

The aim of this study was to establish which dimensions of social support are used within physiotherapy sessions for individuals with schizophrenia.

METHOD

A cross sectional international survey design of specialist mental health physiotherapists was undertaken.

RESULTS

Forty mental health physiotherapists provided in depth accounts of the four functional dimensions of social support (informational, tangible, esteem and emotional) and the one structural dimension (importance of group exercise). The results illustrate how these different dimensions of social support are used by physiotherapists to engage patients and identify the value of group work as a specific form of support. Specifically the importance of all types of support was reported and this helped to provide a detailed consideration to the skills that mental health physiotherapist have.

CONCLUSION

Providing social support is a significant part of the rehabilitation professionals' role. The current results advance the current understanding of how social support is provided to individuals with schizophrenia in rehabilitation settings.

A narrative synthesis investigating the use and value of social support to promote physical activity among individuals with schizophrenia

PURPOSE

To review and synthesise the literature detailing the use of social support to facilitate physical activity participation in individuals with schizophrenia.

METHOD

A systematic review of major electronic databases was conducted to identify literature regarding the use of social support to promote physical activity among people with schizophrenia. A narrative synthesis was undertaken in four stages, including development of a theory, developing a preliminary synthesis, exploring relationships and assessing the robustness of the synthesis.

RESULTS

From a total of 110 studies, 23 met the inclusion criteria including 883 individuals with schizophrenia. Informational support was the most documented form of social support, followed by emotional, esteem and tangible. Providers included research personnel, healthcare professionals, family members and peers. Details of the content of the different dimensions of functional support are given. Social support appears to have an important role to help individuals with schizophrenia initiate, comply and adhere with exercise interventions. Social support may have an indirect benefit on weight maintenance. However, due to the limitations of the selected literature, it was difficult ascertain what the (in)direct benefit of social support are on health outcomes.

CONCLUSIONS

Social support appears to play a pivotal role in initiating physical activity as well as ensuring compliance and adherence to physical activity. Future research is required to investigate the optimal type and mode of delivery of social support on health outcomes.

IMPLICATIONS FOR REHABILITATION

Limited evidence is available that considers the role, value and use of social support within physical activity interventions for individuals with schizophrenia. Social support appears most likely to aid an individual's initiation, adherence and compliance to physical activity interventions. There may be an indirect benefit of social support on maintaining or enhancing health outcomes.

A systematic review and meta-analysis of exercise interventions in schizophrenia patients

BACKGROUND

The typically poor outcomes of schizophrenia could be improved through interventions that reduce cardiometabolic risk, negative symptoms and cognitive deficits; aspects of the illness which often go untreated. The present review and meta-analysis aimed to establish the effectiveness of exercise for improving both physical and mental health outcomes in schizophrenia patients.

METHOD

We conducted a systematic literature search to identify all studies that examined the physical or mental effects of exercise interventions in non-affective psychotic disorders. Of 1581 references, 20 eligible studies were identified. Data on study design, sample characteristics, outcomes and feasibility were extracted from all studies and systematically reviewed. Meta-analyses were also conducted on the physical and mental health outcomes of randomized controlled trials.

RESULTS

Exercise interventions had no significant effect on body mass index, but can improve physical fitness and other cardiometabolic risk factors. Psychiatric symptoms were significantly reduced by interventions using around 90 min of moderate-to-vigorous exercise per week (standardized mean difference: 0.72, 95% confidence interval -1.14 to -0.29). This amount of exercise was also reported to significantly improve functioning, co-morbid disorders and neurocognition.

CONCLUSIONS

Interventions that implement a sufficient dose of exercise, in supervised or group settings, can be feasible and effective interventions for schizophrenia.

Selection, use and psychometric properties of physical activity measures to assess individuals with severe mental illness: a narrative synthesis

This research provides a critical consideration of the outcome measures used to assess physical activity in individuals with severe mental illness. A narrative synthesis was utilised to provide a simple juxtapose of the current research. A sensitive topic-based search strategy was conducted in order to identify studies that met the eligibility criteria. Fifty two studies met the inclusion criteria and 5 were identified specially as validation studies. The current research identified several methodological shortcomings. The justification and choice of outcome measure used is often weak and only five studies have validated a specific outcome measure of physical activity. Within these validation studies, the validation process often lacked a consideration of agreement between measures. Accelerometers have been most frequently used as a criterion measure, notably the RT3 tri-axial accelerometer. Objective based measures may be best placed to consider physical activity levels, although, methodological considerations for the utilization of such tools is required. Self-report questionnaires have benefits for use in this population but require further validation. Researchers and clinicians need to carefully consider what outcome measure they are using and be aware of the development, scope and purpose of that measure.

Increased mortality in schizophrenia due to cardiovascular disease - a non-systematic review of epidemiology, possible causes, and interventions

BACKGROUND

Schizophrenia is among the major causes of disability worldwide and the mortality from cardiovascular disease (CVD) is significantly elevated. There is a growing concern that this health challenge is not fully understood and efficiently addressed.

METHODS

Non-systematic review using searches in PubMed on relevant topics as well as selection of references based on the authors' experience from clinical work and research in the field.

RESULTS

In most countries, the standardized mortality rate in schizophrenia is about 2.5, leading to a reduction in life expectancy between 15 and 20 years. A major contributor of the increased mortality is due to CVD, with CVD mortality ranging from 40 to 50% in most studies. Important causal factors are related to lifestyle, including poor diet, lack of physical activity, smoking, and substance abuse. Recent findings suggest that there are overlapping pathophysiology and genetics between schizophrenia and CVD-risk factors, further increasing the liability to CVD in schizophrenia. Many pharmacological agents used for treating psychotic disorders have side effects augmenting CVD risk. Although several CVD-risk factors can be effectively prevented and treated, the provision of somatic health services to people with schizophrenia seems inadequate. Further, there is a sparseness of studies investigating the effects of lifestyle interventions in schizophrenia, and there is little knowledge about effective programs targeting physical health in this population.

DISCUSSION

The risk for CVD and CVD-related deaths in people with schizophrenia is increased, but the underlying mechanisms are not fully known. Coordinated interventions in different health care settings could probably reduce the risk. There is an urgent need to develop and implement effective programs to increase life expectancy in schizophrenia, and we argue that mental health workers should be more involved in this important task.

Exercise capacity and quality of life in patients with schizophrenia

The aim of this study was to resolve the relationship between physical capacity (PC) and quality of life (Qol) in schizophrenic patients and healthy controls. 31 patients (PG: 18 male, 13 female) and a control group (CG) of 50 healthy subjects (15 male, 35 female) were involved. PC was assessed as peak oxygen uptake [VO2peak, (ml (min kgKG)(-1))] and power output expressed as watts per kilogram (W kg(-1)). Qol was assessed using the SF-36 questionnaire. Patients with schizophrenia showed reduced VO2peak (male: PG 29 ± 5 vs. CG 44 ± 10; female: PG 21 ± 4 vs. CG 30 ± 8) and power output (male: PG 2.04 ± 0.47 vs. CG 3.43 ± 0.70; female PG 1.40 ± 0.28 vs. CG 2.43 ± 0.52). Scales of the SF-36 questionnaire were lower in the PG. While in the CG correlations were found between PC and several subscales of Qol, this was not the case in the PG. The restricted PC seen in the PG showed no relation to their subjectively assessed worsened Qol, which would indicate that schizophrenic patients evaluate limitations arising from this differently than healthy control subjects.

The effects of physical exercise in schizophrenia and affective disorders

Affective and non-affective psychoses are severe and frequent psychiatric disorders. Amongst others, they not only have a profound impact on affected individuals through their symptomatology, but also regarding cognition, brain structure and function. Cognitive impairment influences patients' quality of life as well as their ability to work and being employed. While exercise therapy has been implemented in the treatment of psychiatric conditions since the days of Kraepelin and Bleuler, the underlying mechanisms have never been systematically studied. Since the early 1990s, studies emerged examining the effect of physical exercise in animal models, revealing stimulation of neurogenesis, synaptogenesis and neurotransmission. Based on that body of work, clinical studies have been carried out in both healthy humans and in patient populations. These studies differ with regard to homogenous study samples, sample size, type and duration of exercise, outcome variables and measurement techniques. Based on their review, we draw conclusions regarding recommendations for future research strategies showing that modern therapeutic approaches should include physical exercise as part of a multimodal intervention programme to improve psychopathology and cognitive symptoms in schizophrenia and affective disorders.

Prerequisites for a healthy lifestyle-experiences of persons with psychosis

The purpose of this study is to explore prerequisites for a healthy lifestyle as described by individuals diagnosed with psychosis. Forty participants who had performed a lifestyle intervention focusing on physical activities and lifestyle education were interviewed. Conventional content analysis was used. The results are described in two categories: (1) Individual Prerequisites and (2) Being a Part of Society. The individuals said that they got stuck in a state of planning without taking action. It was pointless to make a bigger effort because the psychotic disorder could, at any time, worsen the prerequisites. They also said that they wanted to live like everybody else and therefore tried to adopt a normal lifestyle. Future interventions or professional support by mental health nurses and other health care givers should target the transition from planning to action to achieve a healthy lifestyle, and should help the individual to taking part in society.

The health benefits and challenges of exercise training in persons living with schizophrenia: a pilot study

BACKGROUND

In addition to the hallmark cognitive and functional impairments mounting evidence indicates that schizophrenia is also associated with an increased risk for the development of secondary complications, in particular cardio-metabolic disease. This is thought to be the result of various factors including physical inactivity and the metabolic side effects of psychotropic medications. Therefore, non-pharmacological approaches to improving brain health, physical health, and overall well-being have been promoted increasingly.

METHODS

We report on the health-related physical fitness (body composition, blood pressure, heart rate, and aerobic fitness) and lipid profile of persons living with schizophrenia and effective means to address the challenges of exercise training in this population.

RESULTS

There was a markedly increased risk for cardio-metabolic disease in 13 persons living with schizophrenia (Age = 31 ± 7 years) including low aerobic fitness (76% ± 34% of predicted), reduced HDL (60% of cohort), elevated resting heart rate (80% of cohort), hypertension (40% of cohort), overweight and obesity (69% of cohort), and abdominal obesity (54% of cohort). Individualized exercise prescription (3 times/week) was well tolerated, with no incidence of adverse exercise-related events. The exercise adherence rate was 81% ± 21% (Range 48%-100%), and 69% of the participants were able to complete the entire exercise training program. Exercise training resulted in clinically important changes in physical activity, aerobic fitness, exercise tolerance, blood pressure, and body composition.

CONCLUSION

Persons living with schizophrenia appear to be at an increased risk for cardio-metabolic disease. An individualized exercise program has shown early promise for the treatment of schizophrenia and the various cognitive, functional, and physiological impairments that ultimately affect health and well-being.

Soccer practice as an add-on treatment in the management of individuals with a diagnosis of schizophrenia

Physical activity is an important aspect of good health for everyone; it is even more important for psychiatric patients who usually live an unhealthy lifestyle. In recent years, there has been growing focus on the use of soccer as a vehicle to improve the health of subjects with severe mental illness. The aim of this study was to investigate the effects of soccer practice on the self-reported health quality of life (SRHQL) and sports performance (SP) in psychotic subjects. Eighteen male patients with diagnosis of schizophrenia were randomized into either a trained (TG) or a control group (CG). The TG was trained for 12 weeks using two soccer training sessions per week. The CG did not perform any regular sports activity during the experimental period. Anthropometric measurements, SRHQL, personal time records in a 30 meter sprint test and slalom test running with a ball were evaluated before and after the experimental period. SRHQL was assessed using Short Form-12 questionnaire measuring physical and mental component summary scores. After the training period, the TG showed a relevant decrease by 4.6% in bodyweight (BW) and body mass index compared to baseline. Conversely, the CG showed an increased BW and body mass index by 1.8% from baseline to posttest. Moreover, after 12 weeks we found that control patients increased their BW significantly when compared to trained patients (Δ = 5.4%; P < 0.05). After the training period, comparing the baseline TG's Short Form-12-scores to posttest results, we found an improvement of 10.5% and 10.8% in physical component summary and mental component summary, respectively. In addition, performances on the 30 meter sprint test and slalom test running with a ball in the TG improved significantly (P < 0.01) from baseline to posttest when compared to CG. Soccer practice appears able to improve psychophysical health in individuals with diagnosis of schizophrenia. Indeed, our study demonstrated that programmed soccer physical activity could reduce antipsychotic medication-related weight gain and improve SRHQL and sports performance in psychotic subjects.
