The purpose of this study was to examine the effects of depleted self-control strength on skill-based sports task performance. Sixty-two participants completed the following: a baseline dart-tossing task (20 tosses), with measures of accuracy, reaction time, and myoelectrical activity of the arms taken throughout; a self-control depletion (experimental) or a nondepletion (control) manipulation; and a second round of dart tossing. As hypothesized, participants in the experimental condition had poorer mean accuracy at Round 2 than control condition participants, and a significant decline in accuracy from Round 1 to Round 2. Experimental condition participants also demonstrated poorer consistency in accuracy compared with control condition participants at Round 2 and a significant deterioration in consistency from Round 1 to Round 2. In addition, consistency in reaction time improved significantly for the control group but not for the experimental group. The results of this study provide evidence that ego depletion effects occur in the performance of a skill-based sports task.
本研究旨在探讨自我控制力量损耗对基于技能的运动任务表现的影响。62 名参与者完成了以下任务：基线飞镖投掷任务（20 次投掷），在整个过程中测量准确性、反应时间和手臂的肌电活动；自我控制损耗（实验）或非损耗（对照）操作；第二轮飞镖投掷。正如假设的那样，实验组参与者在第二轮的平均准确性比对照组参与者差，且从第一轮到第二轮的准确性显著下降。与对照组参与者相比，实验组参与者在第二轮的准确性一致性也较差，且从第一轮到第二轮的一致性明显恶化。此外，对照组的反应时间一致性显著提高，而实验组则没有。本研究结果提供了证据，表明自我损耗效应会出现在基于技能的运动任务的表现中。
