乒乓球与游泳训练儿童的执行功能比较研究

Primary study on executive function in children with Ping-Pong training and swimming training

目的探讨接受不同类型运动训练儿童的执行功能特点。方法以40名参加乒乓球训练(乒乓球组)和41名参加游泳训练(游泳组)的6～9岁儿童为研究对象,分别完成GO/NOGO任务,采集和分析两组儿童的行为学指标(反应时间和正确率)及事件相关电位成分N2的波幅。结果与乒乓球组比较,游泳组GO和NOGO的反应时间较快,而正确率较低,差异均有统计学意义(P<0.05和P<0.01)。游泳组和乒乓组脑电图CPz点NOGO-N2的波幅分别为(-11.36±9.4)μV和(-7.55±7.99)μV,组间比较差异有统计学意义(P<0.05)。结论接受乒乓球训练的儿童在抑制性控制方面强于接受游泳训练的儿童。

Objective To investigate the executive function of children with different sports training. Methods Forty children with Ping-Pong training （ Ping-Pong group） and 41 children with swimming training （ swimming group）, aged 6 - 9 years, completed GO/NOGO task. Behavioral data （reaction time and accuracy） and event related potential component N2 were collected and analyzed. Results The reaction time was significantly faster and accuracy significantly lower of GO task and NOGO task in swimming group than in Ping-Pong group（P 〈 0. 05 and P 〈 0. 01）. There were significant differences in the amplitude of NOGO-N2 on site CPz between swimming group and Ping-Pong group[ - 11.36 ± 9.4） μV vs （ - 7.55 ± 7.99） μV, P 〈 0.05]. Conclusion The inhibitory function of children with Ping-Pong training is stronger than those with swimming training.
