The aim of this study was to examine the birthdates distribution of French male soccer players (n = 363,590) who dropped out during or after the 2006-2007 season, to determine whether the relative age effect is linked to dropout behaviour. An over-representation of players born late in the competitive year was observed among dropouts, from the U-9 to the(More)
Self-determination theory posits that satisfaction of three basic psychological needs-autonomy, competence, and relatedness-are required for psychological well-being, and a recent study showed that the balance in the satisfaction of these three needs independently affects well-being. The present investigation builds on these findings by examining the(More)
The relative age effect (RAE) is considered a common phenomenon in elite sport. Howeven it has not been examined systematically in previous research, and the mechanisms likely to generate or to limit such an effect are little understood. This paper investigates the prevalence of the RAE in French professional championship-level players, taking into account(More)
The relative age effect (RAE) is a biased distribution of elite athletes' birthdates, with an overrepresentation of those born at the beginning of the competitive year and an underrepresentation of those born at the end. Despite an abundant literature, the impact of sex on this phenomenon remains neglected by most researchers. This study investigated the(More)
Implementing theory-based interventions is an effective way to influence physical activity (PA) behaviour in the population. This meta-analysis aimed to (1) determine the global effect of theory-based randomised controlled trials dedicated to the promotion of PA among adults, (2) measure the actual efficacy of interventions against their theoretical(More)
Despite evidence for its health-related benefits, little is known on the psychological predictors of the participation in leisure activities across the lifespan. Therefore, this study aimed to identify whether personality is associated with a variety of different types of activities, involving physical, cognitive, and social components. The samples included(More)
BACKGROUND Several meta-analyses have examined the role of exercise interventions in improving psychological outcomes in cancer survivors but most did not focus on adjuvant therapy period and did not investigate the optimal dose of exercise needed. The present meta-analysis examines the impact of exercise interventions delivered at this particular period on(More)
This study investigated the psychological characteristics of professional golfers and their relation to golf performance. The aims of the study were (a) to provide descriptive data on professional golfers, (b) to test possible differences between successful and unsuccessful players and (c) to estimate whether psychological characteristics could predict golf(More)
Past studies have found that risk perceptions of suffering from diseases play an important role in the development of intentions to perform physical activity (PA). According to the behaviour motivation hypothesis, perceived risk could be positively and directly related to PA, but this possibility has been ignored and/or underestimated. Accounting for recent(More)
BACKGROUND Relatively little is known about the contribution of students' beliefs regarding the nature of academic ability (i.e. their implicit theories) on strategies used to deal with examinations. AIMS This study applied Dweck's socio-cognitive model of achievement motivation to better understand how students cope with examinations. It was expected(More)
