摘要
目的:应用事件相关电位(event-related potential,ERP),考察视觉运动追踪训练提高网球运动员知觉预测能力的效果与机制。方法:采用时间定格任务,将22名职业网球运动员随机分成2组(对照组和实验组),实验组被试运用视觉运动追踪训练系统v1.0进行视觉运动追踪训练,对照组被试不进行任何干预。在不同击球时间点(击球后120、240和360 ms)记录知觉预测的行为学指标及脑电(electroencephalogram,EEG)数据。结果:实验组被试对击球落点的判断正确率更高;在击球后360 ms,实验组被试诱发更大的枕区P1;各时间点,枕区P3波幅组别主效应显著,实验组诱发更大的P3。结论:视觉运动追踪训练可提高网球运动员的知觉预测能力。
Objectives:The study is to investigate the effect of visual motion tracking training on improving tennis players’perceptual anticipation ability and the mechanism underlying it by using event-related potential(ERP).Methods:Twenty-two professional tennis players were randomly divided into two groups:The control group and the training group.The training group finished their training by visual motion tracking training system v1.0,while the control group was not subject to any interference.The behavioral and electroencephalogram(EEG)data of all participants were recorded through sport decision-making paradigm at different hitting time points(120 ms after hitting,240 ms after hitting and 360 ms after hitting).Results:The behavioral results showed that the training group had higher accuracy rate in ball landing site anticipation than the control group.After hitting the ball for 360 ms,the training group was tested to induce a larger occipital area P1.At each time point,the main effect of the P3 amplitude group in the occipital area was significant,and the training group induced larger P3.Conclusions:These results suggest that visual motion tracking training can improve the perception anticipation ability of tennis players.
