The development of burnout in the vocation of sports coaching is a process that can take months or even years. Unfortunately, there is a paucity of longitudinal examination of coaches’ burnout, stress, and recovery. The present study investigated burnout, stress, and recovery of full and part-time coaches to examine possible changes during the course of the season. Twenty-five full-time and 45 part-time active German coaches of different sports and competition levels completed the German coaches’ version of the MBI and the RESTQ for Coaches at three time points. Inferential statistical analysis revealed significant changes of full-time coaches’ stress and recovery scores over the course of the season. Moreover, the work hours per week were significantly higher at the end of the season. Post hoc analysis revealed that full-time coaches whose values of perceived success decreased over the season showed increased emotional stress and decreased recovery values. Part-time coaches reported consistent stress experiences. Consequently, findings suggest that full-time coaches experienced increased emotional stress, invested more time, and had insufficient recovery during the season. Thus, the results highlighted the significant role of recovery for full-time coaches and were particularly important to enhance the understanding of coaches’ work.
