Exertion of Self-Control Increases Fatigue, Reduces Task Self-Efficacy, and Impairs Performance of Resistance Exercise

The purpose of this study was to investigate sequential indirect pathways by which self-control exertion affects resistance exercise performance through fatigue and task self-efficacy. Participants (N = 50) completed 2 sets of maximum repetitions at submaximal loads on bench press and leg extension resistance exercises separated by a Stroop task, which was either congruent (control) or incongruent (self-control exertion). Fatigue was assessed …
