Achnak S, Rigotti T, Vantilborgh T. Examining how different social account timings influence stress resolution in the aftermath of a psychological contract breach. Sci Rep 2022; 12:22021. [PMID: 36539427 PMCID: PMC9768172 DOI: 10.1038/s41598-022-25728-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Accepted: 12/05/2022] [Indexed: 12/24/2022] Open
Abstract
A great deal of empirical research on the consequences of a psychological contract breach (PCB) has overlooked the role of time in understanding individuals' reactions to a PCB. Moreover, psychological contract research primarily focuses on how employees react to perceptions of a PCB, while questions regarding how the organization's responsiveness (i.e., social account) might impact these reactions remain unanswered. We aimed to enhance the understanding of stress reactions and recovery that are triggered by PCB perceptions and stimulate empirical research that treats psychological contracts as a dynamic phenomenon. Drawing on the conservation of resources theory, we investigated how social account delivery timing-and its subjective experience-influences individuals' stress resolution processes in the aftermath of a PCB. To this end, we used an experimental design and assessed participants' physiological (i.e., heart rate) and psychological (i.e., self-report) stress reactions after inducing a breach. Our results underscore that a PCB is experienced as a stressful event. In addition, we find that social account timing influences heart rate recovery following a PCB. We discuss the theoretical and practical implications of our findings and offer recommendations for practitioners.

Abstract
OBJECTIVES Globally, 20-25% of people will experience chronic pain in their lifetime. Dance is a physical activity with psychosocial benefits which may positively impact pain. This review aimed to investigate the effect of dance interventions on the experience of pain, by quantitative measures and qualitative themes. METHODS Seven major databases were searched from inception to January 2021. Two independent reviewers screened articles at each stage. Qualitative and quantitative studies were included if the dance interventions lasted over 6 weeks, participants reported pain longer than 3 months, and pain was an outcome of the study. All articles were critically appraised using appropriate Joanna Briggs Institute tools and data were collated using results-based convergent synthesis. RESULTS From 23,628 articles 34 full papers were included, with a total of 1254 participants (75.2% female). Studies predominantly investigated individuals with Fibromyalgia (26%) and generalised chronic pain (14%), with aerobic dance (20.7%) and Biodanza (20.7%) the most common dance genres investigated. Overall, 74% of studies noted either reduced pain through quantitative pain measures or qualitative themes of improved pain experience (88% for chronic primary pain and 80% for chronic secondary musculoskeletal pain). DISCUSSION There were positive effects of dance on chronic primary and secondary musculoskeletal pain across diverse populations. A variety of study designs and interventions noted improved pain measures and themes around pain coping and acceptance, with all dance therapies showing improvements, particularly when performed for 60-150 minutes duration weekly. Dance should be considered as an effective adjunct in the management of chronic pain.

A Practice-Inspired Mindset for Researching the Psychophysiological and Medical Health Effects of Recreational Dance (Dance Sport). Front Psychol 2021; 11:588948. [PMID: 33716840 PMCID: PMC7950321 DOI: 10.3389/fpsyg.2020.588948] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Accepted: 12/11/2020] [Indexed: 11/13/2022] Open
Abstract
“Dance” has been associated with many psychophysiological and medical health effects. However, varying definitions of what constitute “dance” have led to a rather heterogenous body of evidence about such potential effects, leaving the picture piecemeal at best. It remains unclear what exact parameters may be driving positive effects. We believe that this heterogeneity of evidence is partly due to a lack of a clear definition of dance for such empirical purposes. A differentiation is needed between (a) the effects on the individual when the activity of “dancing” is enjoyed as a dancer within different dance domains (e.g., professional/”high-art” type of dance, erotic dance, religious dance, club dancing, Dance Movement Therapy (DMT), and what is commonly known as hobby, recreational or social dance), and (b) the effects on the individual within these different domains, as a dancer of the different dance styles (solo dance, partnering dance, group dance; and all the different styles within these). Another separate category of dance engagement is, not as a dancer, but as a spectator of all of the above. “Watching dance” as part of an audience has its own set of psychophysiological and neurocognitive effects on the individual, and depends on the context where dance is witnessed. With the help of dance professionals, we first outline some different dance domains and dance styles, and outline aspects that differentiate them, and that may, therefore, cause differential empirical findings when compared regardless (e.g., amount of interpersonal contact, physical exertion, context, cognitive demand, type of movements, complexity of technique and ratio of choreography/improvisation). Then, we outline commonalities between all dance styles. We identify six basic components that are part of any dance practice, as part of a continuum, and review and discuss available research for each of them concerning the possible health and wellbeing effects of each of these components, and how they may relate to the psychophysiological and health effects that are reported for “dancing”: (1) rhythm and music, (2) sociality, (3) technique and fitness, (4) connection and connectedness (self-intimation), (5) flow and mindfulness, (6) aesthetic emotions and imagination. Future research efforts might take into account the important differences between types of dance activities, as well as the six components, for a more targeted assessment of how “dancing” affects the human body.

Abstract
The scope of this study was to analyze the relationship between quality of life, fatigue and injuries among professional Brazilian ballroom dancers. A total of 320 professionals from the five regions of Brazil participated, and the data were collected through a self-administered online questionnaire concerning general information, WHOQOL-bref, Yoshitake Fatigue Questionnaire and Injury Identification in Dancers Questionnaire. For data analysis, descriptive statistics were used, followed by inferential analysis and the Multiple Linear Regression test. The results show that greater fatigue is associated with a negative quality of life, revealing that, for each additional increment in total fatigue, the quality of life is expected to decrease by 0.218 points in the physical domain; 0.226 points in the psychological domain; 0.420 points in the social domain; and 0.304 points in the environmental domain. In contrast, the incidence and intensity of injuries were not associated with quality of life. The conclusion drawn is that the context of professional ballroom dance can influence both the presence of fatigue and the quality of life. It is suggested that health professionals working with these dancers perform multifactorial interventions in order to reduce fatigue, attenuating its effects on quality of life.

Abstract
On duty, police officers are exposed to a variety of acute, threatening stress situations and organizational demands. In line with the allostatic load model, the resulting acute and chronic stress might have tremendous consequences for police officers' work performance and psychological and physical health. To date, limited research has been conducted into the underlying biological, dynamic mechanisms of stress in police service. Therefore, this ecological momentary assessment study examined the associations of stress, mood and biological stress markers of a 28-year-old male police officer in a N-of-1 study over three weeks (90 data points). Four times a day (directly after waking up, 30 minutes later, 6 hours later, before going to bed), he answered questions about the perceived stress and mood using a smartphone application. With each data entry, he collected saliva samples for the later assessment of salivary cortisol (sCort) and alpha-amylase (sAA). In addition, data was collected after six police incidents during duty. sCort and sAA were not related to perceived stress in daily life and did not increase in police incidents. Regarding mood measures, deterioration of calmness, but not valence and energy was associated with perceived stress. The results suggest continued police service to constitute a major chronic stressor resulting in an inability to mount a proper response to further acute stress. As an indicator of allostatic load, psychological and biological hyporesponsivity in moments of stress may have negative consequences for police officers' health and behavior in critical situations that require optimal performance. Prospectively, this research design may also become relevant when evaluating the efficacy of individualized stress management interventions in police training.

The effects of mindfulness training on competition-induced anxiety and salivary stress markers in elite Wushu athletes: A pilot study. Physiol Behav 2019; 210:112655.

Abstract
OBJECTIVE Due to the impact of stress and related psychophysiological responses on competitive performance, psychological interventions that reduce stress and may thus increase athletic performance need to be evaluated. In this pilot study, the effects of a mindfulness-based intervention (MBI) on competitive anxiety, self-confidence and mindfulness, and autonomic and endocrine stress responses to a competition in elite athletes were explored. METHODS Twenty-six male elite Wushu athletes (N = 26) were randomly assigned to either MBI (8 weeks) or a wait-list control group. Both groups participated in three competitions at baseline, immediately post intervention, and at a 2-month follow-up. Athletes completed the Competitive State Anxiety Inventory-2 prior to the competitions. Saliva, from which the stress markers cortisol (sCort) and alpha-amylase (sAA) were determined, was collected prior to and after competitions as well as after awakening and in the evening of competition days. RESULTS Repeated measures ANOVAs showed that the MBI group, but not the wait-list control group, demonstrated an increase in self-confidence and mindfulness and a decrease in competitive anxiety from baseline to post intervention (all p < .001, all ɳp2 > 0.39). The MBI group exhibited lower sCort daily levels (p = .001, ɳp2 = 0.332) and lower sCort (p = .013, ɳp2 = 0.121) and sAA responses (p = .022, ɳp2 = 0.119) to the competition after the intervention. Daily sAA was unaffected by the intervention (p = .742, ɳp2 = 0.011). These changes remained stable up to the 2-month follow-up. CONCLUSIONS The present pilot study suggested that mindfulness-based intervention might be associated with a diminished physiological and psychological stress responses to competition. Whether this in turn translates to change in performance needs to be examined in future studies with larger samples. Moreover, different sport activities need to be considered before findings can be generalized.

Abstract
Athletes often report on heightened stress, higher disease susceptibility, and a deterioration in mood and performance throughout periods of high training load and competitions. This paper presents a single-case study combining different research approaches to monitor the dynamic, idiosyncratic responses to competitive stress in elite sports using the example of professional ballroom dancing. Throughout an 8-month period (313 data points), one international-level female dancer provided data on mood, stress, and fatigue. In parallel, she collected saliva samples for the assessment of cortisol (sCort) and alpha-amylase (sAA). A hair strand was collected every 3 months to examine cumulative cortisol secretion. As expected, perceived stress was related to a reduction in well-being. On a daily basis, sCort predicted lower fatigue. In addition, tournaments resulted in a 3-fold and a 2-fold increase in sCort and sAA, respectively, and there was a pronounced drop in hair cortisol in the aftermath of a surgery-related break from dancing. We confirm competitive ballroom dancing to constitute a major stressor with immediate and prolonged consequences for self-reported well-being and biological stress markers. Single-case studies offer much potential for the observation of complex dynamic associations. In a next step, this approach will also become relevant when evaluating the efficacy of preventive and therapeutic interventions on an individual level.

Abstract
Objective A high unilateral load to the musculoskeletal system is specific for formation dance. Due to the lack of data the aim of this study was the side-related (right – left) analysis of strength- and balance capability subject to injuries, gender and performance standards. Methods N = 51 dancers (m: n = 24, f: m = 27) of two performance levels participated in this cross-sectional study. Double-sided tests of the isometric maximal strength of relevant muscle groups and the balance capability were carried out. The tests were supplemented by a self report questionnaire. Results Tests of the isometric maximal strength in the elite performance level showed significant differences between either side of the body. As to the balance capability, no significant side-related differences could be found in. Correlations between the strength capability and the injuries could be observed in either group. Conclusion The significant strength differences are presumably caused by the right-sided load in the dance-specific movements. The cautious conclusion that movement patterns challenge the stability of either side of the body likewise may be allowed. The increased injury frequency at the muscularly stronger side of the body primarily results from an overload. An additive muscular training should be considered as a preventive measure.

Abstract
BACKGROUND Worry or fear related to speaking in front of others, or more broadly, communicating and interacting with others, is common. At elevated levels, however, it may contribute to heightened stress reactivity during acute speaking challenges. The purpose of this study was to examine multi-system physiological stress reactivity in the context of high-stakes public speaking while considering the impact of hypothesized individual difference risk factors. METHODS University student participants (n = 95) delivering speeches as a heavily-weighted component of their final grade had saliva samples collected immediately prior to speaking, immediately after, and 20 min after speech completion. Saliva samples were assayed for alpha amylase (sAA), cortisol, and interleukin-1 beta (IL-1β). Self-reported communication anxiety, social interaction anxiety, rejection sensitivity, and sex were assessed as risk factors for heightened stress reactivity. RESULTS Salivary sAA, cortisol, and IL-1β significantly changed following speech delivery. Multivariate analyses demonstrated that elevated levels of self-reported communication anxiety and social interaction anxiety were independently associated with increased cortisol and IL-1β responses and combined to enhance HPA axis and inflammatory cytokine activity further (i.e., cortisol and IL-1β AUCI). Sex and rejection sensitivity were unrelated to physiological stress reactivity. CONCLUSIONS These findings suggest that individuals with elevated communication and interaction fears may be at increased risk of heightened neuroendocrine and inflammatory responses following exposure to acute social stressors. Both types of anxiety may combine to increase physiological reactivity further, with unknown, though likely insalubrious, health consequences over time.

Abstract
In this study, we tested the hypotheses that, relative to the maximum capacities, ballroom dancing is more intensive for females than males, and that the hold technique (female vs. male) regulates dancing intensity. Ten dance couples were tested in a maximal treadmill test, competition simulation, and stationary dance hold position. Peak heart rate and relative oxygen consumption were measured during the tests, except that oxygen consumption was not measured during competition simulation. Regardless of gender, heart rate increased similarly in the treadmill test and in the competition simulation. In the treadmill test, females achieved an oxygen consumption of 78% of the males (p < 0.05). Compared with males, females achieved 14% higher heart rate (p < 0.05) and similar oxygen consumption during the hold position. Heart rate during competition simulation relative to maximum was greater for females than males. Both heart rate and oxygen consumption measured during the hold, relative to maximum, were greater for females than males. It is concluded that lower class ballroom dancers perform at their vita maxima during competition simulation. Using heart rate as an intensity indicator, ballroom dancing is more intensive for females because of their unique hold technique.

Abstract
BACKGROUND This study examined autonomic responses (salivary alpha-amylase, sAA; heart rate, HR) to repeated psychosocial stress as a candidate mechanism linking autonomic hyper-arousal and sensitization to the occurrence of panic disorder (PD). METHODS Thirty-three patients with PD and 34 healthy controls were exposed to the Trier Social Stress Test (TSST) twice on consecutive days. RESULTS sAA changes were comparable between PD and controls on both testing days with overall decreasing sAA responses (delta) on day two. In contrast, HR delta increased on day two in both groups. This sensitization was driven by female controls while male PD showed most pronounced HR changes to the first TSST. CONCLUSIONS Overall, a general autonomic hyper-arousal in PD could not be confirmed. In contrast, sAA responses slightly habituated to repeated stress. Whether sAA findings mirror assumed habituation effects of repeated stress exposure on normalizing autonomic reactivity remains to be investigated in longitudinal studies.

Abstract
This study aimed to examine the alterations in physiological and biochemical markers, after 17 weeks of ballet training in high level ballet dancers. Twenty four female ballet dancers from 12 to 15 years old took part in the study. The study followed 17 weeks of ballet training and analyzed changes in body composition, the autonomic nervous system and biochemical variables before and after (post) training. The internal training load was obtained using the session rating of perceived exertion (session-RPE) method, calculated as the mean weekly session-RPE, monotony and strain. After 17 weeks of training there were significant increases in body mass, height, lean body mass, total protein, urea, hemoglobin concentration, testosterone and thyroxine. During this period, decreases in relative body fat, uric acid, red blood cells, C-reactive protein, and ferritin were also found. After the training period, the autonomic modulation demonstrated significant positive alterations, such as increases in parasympathetic related indices. Based on the results obtained we concluded that ballet training led to improvements in body composition and autonomic modulation. In general hematological and biochemical variables demonstrated that the training did not have adverse effects on the health state of the adolescents.

Abstract
Psychological stress has been shown to trigger systemic lupus erythematosus (SLE). However, objective evidence of symptom aggravation due to mental stress is difficult to identify. We aimed to investigate the relationship between SLE disease activity and mental stress, and the usefulness of saliva as an assessment index for stress in patients with SLE.We prospectively assessed the salivary stress hormone and disease-related biomarkers, and questionnaire data regarding stress and depression in 100 patients with SLE and 49 sex- and age-matched normal controls (NCs).Patients with SLE had higher mean salivary α-amylase levels (5.7 ± 4.6 U/mL vs 2.7 ± 2.5 U/mL, P < 0.001), anti-chromatin antibody levels (25.3 ± 22.9 U/mL vs 15.9 ± 10.9 U/mL, P < 0.001), and Beck Depression Index (BDI) scores (11.1 ± 9.2 vs 5.3 ± 5.1, P < 0.001) than NCs. However, salivary cortisol levels and Perceived Stress Scale (PSS) scores did not differ between the groups. The BDI scores correlated with the SLE disease activity index (SLEDAI) scores (r = 0.253, P = 0.011) and erythrocyte sedimentation rates (r = 0.234, P = 0.019). SLE patients with the highest-quartile PSS scores had significantly increased SLEDAI scores compared to those with the lowest-quartile PSS scores after 4 to 5 months' follow-up. Moreover, SLE patients with elevated SLEDAI scores had higher baseline PSS scores.Patients with SLE showed uncoupling of the sympathetic nervous system and hypothalamic-pituitary-adrenal axis; higher salivary α-amylase and no different cortisol levels compared with NCs. Also, patients with SLE were more depressed, which correlated with disease activity. Furthermore, perceived stress was not correlated with disease activity; however, disease activity worsened several months later with elevated perceived stress levels.

Abstract
Spanish medical graduates who apply for a medical specialty training position (MIR) must take an examination that will shape their future personal and professional lives. Preparation for the test represents an important stressor that persists for several months. The aim of this study was to elucidate the stress pattern of this group and evaluate possible changes in the circadian rhythm of cortisol release in medical graduates preparing for this test. A repeated-measures longitudinal study was performed, measuring the salivary cortisol concentrations in 36 medical graduates (13 males and 23 females; mean age of 24.2 years) on five sampling days. Five cortisol samples were collected from 07:00 to 21:00 h in order to monitor changes in the circadian rhythm. On all sampling days (except on the day of the official examination), anxiety and psychological stress were evaluated with the Spanish versions of the State-Trait Anxiety Inventory (STAI) and the Perceived Stress Scale (PSS). During the study period, participants showed higher levels of anxiety than the Spanish reference population as well as a progressive increase in self-perceived stress. A significant increase in salivary cortisol concentration was observed in both chronic (study and examination preparation) and acute (examinations) situations. Our results suggest that the cortisol awakening response (CAR) may be a good indicator of anticipatory stress but is unaffected by long-term examination preparation. Comparison of results between the official examination day and the mock examination days yielded evidence that learning may modulate the behavior of the hypothalamic-pituitary-adrenal axis.

Abstract
Dancers are clearly athletes in the degree to which sophisticated physical capacities are required to perform at a high level. The standard complement of athletic attributes - muscular strength and endurance, anaerobic and aerobic energy utilization, speed, agility, coordination, motor control, and psychological readiness - all are essential to dance performance. In dance, as in any athletic activity, injuries are prevalent. This paper presents the research background of dance injuries, characteristics that distinguish dance and dancers from traditional sports and athletes, and research-based perspectives into how dance injuries can be reduced or prevented, including the factors of physical training, nutrition and rest, flooring, dancing en pointe, and specialized health care access for dancers. The review concludes by offering five essential components for those involved with caring for dancers that, when properly applied, will assist them in decreasing the likelihood of dance-related injury and ensuring that dancers receive optimum attention from the health care profession: (1) screening; (2) physical training; (3) nutrition and rest; (4) specialized dance health care; and (5) becoming acquainted with the nature of dance and dancers.

Abstract
PURPOSE OF REVIEW In recent years, a growing interest has emerged in behavioural medicine to examine the role of acute and chronic stress as a predisposing and contributing factor to physical health and illness. For a deeper understanding of these associations, research is in need of biological markers for alterations in biological stress systems. This review will summarize a selection of important recent findings in this area of research. RECENT FINDINGS We will focus on essential peripheral stress-sensitive physiological systems, that is, the hypothalamic-pituitary-adrenal axis, the autonomic nervous system, and the immune system. We will present findings on commonly used stress biomarkers (cortisol, alpha-amylase, pro-inflammatory cytokines) regarding alterations in basal activity and stress-dependent reactivity in these systems, and discuss selected findings on intervention-induced changes of these biomarkers. SUMMARY This review will highlight new developments and guide readers in their choice of suitable study designs and outcomes in behavioural medicine. The reviewed studies included here encourage optimism that the employment of stress biomarkers in behavioural medicine has the potential to significantly improve our understanding of physical health and illness.

Abstract
Creatinine phosphokinase (CPK) and lactate dehydrogenase (LDH) are important biological markers of various myocardial disorders and exercise-induced muscle damage. Lycopene, on the other side, is a natural anti-oxidant with protective action against cardiovascular risk. Fifteen anaerobically trained athletes with elevated LDH and CPK baseline levels were enrolled in this study after undergoing thorough biochemical and cardiovascular evaluation with echocardiocraphy. In nine athletes tomato juice, a lycopene plain juice, was administered during and after exercise, replacing the carbohydrate supplementation beverages commonly used during training for over a 2-month period. Tomato juice administration significantly reduced LDH and CPK levels, which returned back to almost normal levels. At the same time homocysteine and C-reactive protein were also attenuated. No changes were observed in the control group, where the usual carbohydrate supplementation had been followed.
