空手道训练对大学生自我控制能力的影响:来自行为和脑电的证据

The Effect of Karate Training on Self-Control:Evidence from Behavior and Event-Related Potentials

为考察空手道训练能否提高大学生的自我控制能力,研究采用Go/Nogo任务测量个体的认知自控及相应的脑电活动,并加入靠墙直角坐任务测量个体的行为自控能力,比较个体在4周训练干预前后认知和行为自控能力的变化。结果显示,空手道训练组在各项任务中的表现均显著优于无额外运动组,而蹬车运动组介于两组之间且与两组差异均不显著。因此,空手道训练能够稳定有效地提高个体的认知和行为自控能力,原因可能是训练降低了自控资源的易损性。

To investigate whether karate training can improve the self-control ability of college students,we adopted the Go/Nogo task(with event-related potentials analyzed)and the wall-sit task to measure the changes of individuals’cognitive and behavioral self-control before and after 4 weeks of karate training intervention.The results showed that the karate training group was significantly better than that of no additional exercise group in all the measures,whereas the performance of cycling group lay between those two groups with no significant difference from either group.The results indicated that karate training can improve individuals’cognitive and behavioral self-control,probably because training makes the individuals less vulnerable to the effects of self-control resource depletion.
