The effectiveness and superiority of the RCRL approach are verified. Every high-level athlete will eventually see his or her sport career come to an end. Most former athletes will experience changes in their self-definition and everyday behaviors as they accept a nonathletic way of life. The present study aimed to identify discrepancies between actual and former athletes regarding athletic identity, physical activity (PA), and nutrition habits. Actual athletes (AA; n = 122), former athletes (FA; n = 230), and nonathletes (NA; n = 74) were asked to complete an online questionnaire on athletic identity, duration and intensity levels of occupational and leisure time PA, and nutritional habits. FA healthy nutrition score was the lowest of the 3 groups and significantly different from that of AA. Athletic identity and intense and moderate PA during leisure time consistently decreased (p < 0.01) across the 3 groups (AA > FA > NA). No significant difference between FA and NA was found regarding either nutritional habits or type of PA. Sport retirement may affect FA quality of nutritional habits that tends to decline below the NA level, as well as the amount of time spent practicing physical activities during leisure time. Athletic status does not ensure PA practice during sport postcareer.

The purposes of this study were to examine the trajectories of athlete burnout across a 2-month period characterized by high physical, psychological, and social demands to explore (1) whether several subgroups of athletes representing distinct burnout trajectories emerged f
