Detrimental effects of prior self‐control exertion on subsequent sporting skill performance

Abstract

The prior exertion of self‐control has previously been shown to negatively affect physical performance, yet the effects on complex sporting skill performance have not been examined. Therefore, this study examined whether prior self‐control exertion influences performance on a field hockey task, alongside measuring plasma cortisol concentration and attention as potential mechanisms to explain any effects. Following familiarization, 13 male hockey players (20 ± 1 years) participated in a randomized, order‐balanced, crossover design. For the manipulation of self‐control, participants completed an incongruent (self‐control exertion trial) or a congruent (control trial) Stroop task. Skill performance was assessed using a field hockey skills task. Capillary blood samples, for the determination of plasma cortisol concentration, were taken at baseline, post‐Stroop task, and post‐field hockey skills task. Cognitive tests of attention (RVIP and Flanker tasks) were completed following the field hockey skills task. Participants made more errors in the latter stages of the field hockey skills task following self‐control exertion (trial*time interaction, p = 0.041). Participants also made more errors on the RVIP task following self‐control exertion (p = 0.035); yet the time taken to complete the hockey skills task, performance on the flanker task, and plasma cortisol concentrations were unaffected (all p > 0.05). Overall, these findings suggest that prior self‐control exertion has detrimental effects on subsequent sporting skill performance (more errors made on the field hockey task), which may be explained by poorer sustained attention (lower accuracy on the RVIP task). This suggests that athletes should aim to avoid self‐control exertion before a competitive match to optimize performance.

The Role of Gender in Association between Emotional Intelligence and Self-Control among University Student-Athletes

“…The results we obtained differed in some cases from those of other investigators, presumably due to the specific sample of subjects [2,5,7,8,21,43,54,56,57,64]. Student athletes do not represent all young people of a similar age.…”

“…The results of the study revealed that to young athletes, there are links between self-control achievement in sports competitions, motivation, and the weakening of self-control [42]. Harmful prior efforts to strengthen self-control have been identified as this may reduce athletic performance [43].…”
