【摘要】：尽管葡萄糖作为自我控制资源本质的观点仍存争议,但其对状态自控的改善值得肯定。为探讨葡萄糖补给时机对运动员自我损耗的影响,预实验检验改进后的Stroop任务诱发自我损耗的效果,选取36名男性羽毛球运动员,探究自我损耗状态对努力程度、难度和心境得分的影响。实验1:选取72名男性网球运动员,探究补给时机和补给策略对Handgrip任务(坚持性自控任务)坚持时间的影响。实验2:选取72名男性篮球运动员,探讨补给时机和补给策略对Visual-CCPT任务(认知性自控任务)的虚报数、漏报数和反应时的影响。结果发现:1)改进后的Stroop任务可诱发自我损耗状态;2)自我损耗前、后补给葡萄糖均可提升运动员坚持性自控任务的表现;3)自我损耗后补给葡萄糖对于改善认知自控任务表现的效果不大,自我损耗前补给葡萄糖可有效促进运动员认知自控任务的表现。
[Abstract]:Although the view of glucose as the essence of self-control resources is still controversial, its improvement on state self-control is worthy of affirmation. In order to explore the effect of glucose replenishment time on athletes' self-loss, the effect of self-loss induced by improved Stroop task was tested by pre-experiment. 36 male badminton players were selected to explore the effect of self-depletion state on the degree of effort. The impact of difficulty and mood scores. Experiment 1: 72 male tennis players were selected to explore the influence of replenishment time and replenishment strategy on the persistence time of Handgrip task (persistent self-control task). Experiment 2: 72 male basketball players were selected to explore the effects of replenishment time and replenishment strategy on the false number, missing number and reaction time of Visual-CCPT task (cognitive self-control task). The results showed that: 1) the improved Stroop task could induce self-loss, 2) glucose supplementation before and after self-depletion could improve the performance of athletes' persistence and self-control task. 3) glucose supplementation after self-depletion has little effect on improving the performance of cognitive self-control tasks. Glucose supplementation before self-depletion can effectively promote the performance of athletes' cognitive self-control tasks.
