A multi-sample examination of the relationship between athlete burnout and sport performance.

Athlete burnout potentially has negative consequences for sport performance. However, to the best of our knowledge, empirical studies have yet to examine the relationship between athlete burnout and objective sport performance. Consequently, we aimed to provide a first such examination. To do so, we recruited three samples. We used Sample 1 (n = 106: track and field athletes) to examine the predictive utility of athlete burnout on a single performance, Sample 2 (n = 181: swimmers) to examine whether the findings from Sample 1 can be replicated in a different sport, and Sample 3 (n = 169: track and field athletes) to examine the predictive utility of athlete burnout on peak performance in a three-month period. Finally, having captured three samples each assessing the athlete burnout-performance relationship, we also sought to quantify the combined effect across these samples using a relatively new analytical technique - mini meta-analysis. Results from regression analyses showed that in at least two of the three samples total burnout, reduced sense of accomplishment, and sport devaluation each negatively predicted performance, whereas emotional and physical exhaustion was unrelated to performance. When we combined the samples, mini meta-analysis showed that total burnout, reduced sense of accomplishment, and sport devaluation each displayed a small-to-medium negative and significant meta-correlation with performance. The findings suggest that certain athlete burnout symptoms may indeed have negative consequences for sport performance, and that this is the case when considering a single performance and peak performance.
