本研究旨在探讨自我调节力量耗竭操作对身体耐力（等长握力）任务表现的影响。此外，在耐力任务期间，耗尽对工作前臂肌肉的EMG活动的影响进行了探讨。久坐不动的大学生（N=49）被随机分配到认知耗竭条件（修改Stroop任务）或控制（颜色词）组，并完成两个最大的等距运动耐力试验分离的认知任务。耗竭组的参与者显示出显著性（p
The purpose of the present study was to examine the effects of a self-regulatory strength depletion manipulation on performance of a physical endurance (isometric handgrip) task. In addition, the effect of depletion on EMG activity in the working forearm muscles during the endurance task was explored. Sedentary undergraduates (N=49) were randomly assigned to either a cognitive depletion condition (modified Stroop task) or a control (color word) group and completed two maximal isometric exercise endurance trials separated by the cognitive task. Participants in the depletion group showed significant (p
