- Objective: To extend the understanding of burnout in elite athletes, including personal experiences and perceived antecedents.Design and Methods: Semi-structured in-depth interviews were conducted with 10 Swedish 22- to 26-year-old elite athletes who had quit sport due to burnout. The interview transcripts were inductively analyzed using qualitative conten tanalysis.Results: The findings support the notion of athlete burnout as a multidimensional syndrome. While stressors like multiple demands, ‘‘too much sport,’’ lack of recovery and high expectations were considered primary causes of burnout by the respondents, high motivation, unidimensional athletic identity, self-esteem strivings, high ego goals, negative perfectionist traits and feelings of entrapment were also found to be critical contributors. These restraining factors explained why the athletes continued their participation in sport despite a progressive worsening of their condition, and are therefore potentially crucial in the development of burnout.Conclusion: Athlete burnout appears to be a complex interaction of multiple stressors, inadequate recovery and frustration from unfulfilled expectations, which is explained partly by maladaptive perfectionist traits and goals. This process is fuelled by a strong drive to validate self-worth, sometimes in conjunction with feelings of entrapment.

- It has been demonstrated that physical activity has a small but positive effect on cognition in old age, which suggests that it may be possible to alter the trajectory of age-related cognitive decline. However, our understanding of which aspects of physical activity that are important for modifying cognition remains incomplete. Adopting an exploratory approach in a sample of 115 healthy older adults (65–75 years), the present cross-sectional study used structural equation modelling to investigate the dissociable associations of physical activity (moderate-to-vigorous activity, derived from 7-day accelerometry) and cardiorespiratory fitness (VO2 max, derived from maximal treadmill ergometer test) with multiple latent cognitive abilities (working memory, episodic memory, spatial and verbal reasoning). The results showed a significant positive association between fitness and working memory, when physical activity was statistically controlled for, and a positive association of similar point magnitude between physical activity and episodic memory, when fitness was statistically controlled for, although the latter association did not reach statistical significance. The results add to the foundation for a more careful investigation of the dissociable associations of moderate-to-vigorous physical activity and fitness with cognition in old age, and encourages future research to test the hypothesis that cardiorespiratory fitness benefits working memory via general cerebrovascular effects on grey matter volume, whilst moderate-to-vigorous physical activity benefits episodic memory via effects on neuroplastic processes.

- Objectives: To examine the effects of a 6-month exercise intervention programme (EIP) on physical self-perceptions (PSP) and social physique anxiety (SPA) of non-physically active adolescent Swedish girls. Methods: A true experimental design with randomization into an intervention or control group was used. The empowerment based EIP, offered to the intervention group twice a week for 6 months, consisted of 45-min exercise sessions followed by 15 min of discussions regarding a healthy lifestyle. A variety of exercise activities, chosen by the participants themselves, were used. Twenty-seven participants in the intervention group and 35 in the control group completed the Physical Self-Perception Profile (PSPP) and the Social Physique Anxiety Scale (SPAS) at pre- and posttest and, in addition, physical fitness, weight and height were measured. Results and conclusions: The intent to treat analysis showed no significant improvements in PSPP subdomains, but lower SPAS scores for the intervention group, compared to the control group. However, when using a less conservative analysis, including only those who completed assessments both pre- and post-intervention, the intervention significantly reduced both PSPP subdomain and SPAS scores. The changes in PSPP and SPAS scores were not linked to changes in physiological variables. The results are put in the context of previous longitudinal and review studies, theoretical frameworks and models. The direction of effects, possible mechanisms and limitations of the study are discussed along with practical applications linked to exercise and modern diseases.
