Effects of Glucose Supplementing Time on Ego-depletion of Athletes

Although glucose is still controversial as the essence of self-control resources, its improvement 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 explore 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.
