The influence of in-game emotions on basketball performance.

This study examined the influence of emotions on performance in basketball. Six female basketball players were videotaped in six games. Frequency of performance behaviours was recorded minute-by-minute and indices of successful (SGI) and unsuccessful (UGI) game involvement derived for each player. Post-game, players reported the intensity of experienced emotions (anger, anxiety, embarrassment, excitement and happiness), and the time of the eliciting incident. The only emotion revealed as a significant predictor of SGI was happiness; both anger and embarrassment were significant predictors of increased UGI. Consideration of individual player analyses suggests that there is variation in the magnitude of the influence of emotions on performance and the extent to which this influence was helpful or harmful to performance. The study provides evidence that emotions are associated with changes in game behaviours in competition. Implications for further research examining the emotion-performance relationship are discussed.
