- Few studies have examined the association between sleep and burnout symptoms in elite athletes. We recruited 257 young elite athletes (M-age = 16.8 years) from Swiss Olympic partner schools. Of these, 197 were reassessed 6 months later. Based on the first assessment, 24 participants with clinically relevant burnout symptoms volunteered to participate in a polysomnographic examination and were compared with 26 (matched) healthy controls. Between 12% and 14% of young elite athletes reported burnout symptoms of potential clinical relevance, whereas 4-11% reported clinically relevant insomnia symptoms. Athletes with clinically relevant burnout symptoms reported significantly more insomnia symptoms, more dysfunctional sleep-related cognitions, and spent less time in bed during weeknights (p<.05). However, no significant differences were found for objective sleep parameters. A cross-lagged panel analysis showed that burnout positively predicted self-reported insomnia symptoms. Cognitive-behavioral interventions to treat dysfunctional sleep-related cognitions might be a promising measure to reduce subjective sleep complaints among young elite athletes.

- Objectives: To examine in a sample of young elite athletes (a) the presence of clinically relevant symptoms of burnout and depression, and (b) a possible interaction of perceived stress and mental toughness in the prediction of burnout and depressive symptoms. Design: 6-month prospective study. Methods: A representative sample of 257 young elite athletes (M = 16.82 years, SD = 1.44, 36% females) was recruited in North–Western Switzerland. 197 athletes were followed-up across a 6-month period. Burnout was assessed with the Shirom-Melamed Burnout Measure (SMBM), and depression with the 9-item depression module of the Patient Health Questionnaire (PHQ). Values of ≥4.40 (SMBM) and >14 (PHQ-9) were considered indicative of clinically relevant burnout or depression. Stress perceptions were assessed with the Perceived Stress Scale (PSS), and mental toughness with the Mental Toughness Questionnaire (MTQ). Hierarchical regression analyses were used to test stress-buffering effects. Results: The percentage of athletes with clinically relevant levels of burnout and depressive symptoms was 12% and 9%, respectively. Both cross-sectional and prospective analyses showed that compared to participants with low mental toughness, those with higher mental toughness scores reported significantly fewer mental health issues, when exposed to high stress. By contrast, when stress levels were low, mental toughness was unrelated to psychological health complaints. Conclusions: About every tenth young elite athlete reported burnout or depressive symptoms of potential clinical relevance. While high perceived stress was associated with increased psychological health complaints, mental toughness was able to off-set some of the negative consequences resulting from high stress exposure.

- Objectives: Having psychometrically sound instruments is essential to the understanding of the determinants and consequences of athlete burnout. Therefore, this study examines the psychometric properties of a German version of the Athlete Burnout Questionnaire (ABQ) and its usefulness as a screening tool for the detection of clinically relevant burnout symptoms. Design: Prospective study. Method: 257 young elite athletes were recruited from Swiss Olympic Sport Classes (37% females; M = 16.8 years, SD = 1.4). 197 students were assessed a second time after six months. All students filled in a standardized questionnaire about domain-specific and domain-unspecific burnout symptoms, depressive symptoms, stress, and life satisfaction. Results: Confirmatory factor analysis supported the three-factor structure of the ABQ. Moreover, all subscales had acceptable internal consistency. Support was also found for the convergent validity of the ABQ; all subscales were positively correlated with perceived stress, burnout and depression, whereas negative correlations existed with life satisfaction. By contrast, some ABQ subscales shared only limited variance, the three ABQ subscales did not predict each other across time, and none of the ABQ subscales was suitable for the screening of clinically relevant burnout symptoms. Conclusions: While the factor structure and internal consistency of the ABQ was supported, our study corroborates previous concerns about the psychometric properties and validity of the ABQ. While the ABQ has advanced research on athlete burnout, we hold that further debates about the most suitable way to assess burnout among elite athletes are urgently needed.

Human dopaminergic system in the exercise-cognition link

Tidskriftsartikel (refereegranskat)abstract
- While the dopaminergic system is important for cognitive processes, it is also sensitive to the influence of physical activity (PA). We summarize current evidence on whether PA-related changes in the human dopaminergic system are associated with alterations in cognitive performance, discuss recent advances, and highlight challenges and opportunities for future research.
