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。
Although glucose is still controversial as the essence of self-control resources, its im- provement in state self-control is worthy of recognition. In order to explore the effects of glucose supplementing time on the ego-depletion of athletes, preliminary experiment tests the effects of inducing ego-depletion by the modified Stroop task, and select 36 male badminton players, to ex- plore the impact of the ego-depletion on the effort, difficulty and mood scores. In experiment 1,72 male tennis players were selected to explore the effects of supplementing time and supplementing strategies on the Handgrip task （persistence self-control task）. In experiment 2, 72 male basketball players were selected to explore the effects of supplementing time and supplementing strategies on the commission number, underreporting numbers and response time of Visual-CCPT tasks （cognitive self-control task）. The results shows that the modified Stroop task can induce ego-depletion; before and after the ego-depletion, supplying glucose can enhance the athlete＇ s persistence self-control task performance; after the ego-depletion, supplement for glucose has little effect in improving cognitive self-control task performance; before the ego-depletion glucose can promote the performance of athletes cognitive self-control task effectively.
