知觉预判的差异与大学生运动员训练策略研究

The Differences in Perceptual Anticipation and the Training Strategies

研究采用事件相关电位技术(ERPs),在球落地后的不同时间点上(击球时拍子和球接触瞬间时间点T2、击球后80 ms时间点T3)比较了大学生二级运动员组与新手组对击球线路知觉预判的行为学与神经机制的差异。行为学与ERPs结果表明,大学生二级运动员与新手组在进行知觉预判上存在显著性差异,偶极子定位说明大脑的前额叶皮质、颞叶、枕叶、顶叶都可能参与了知觉预判有关的信息加工。并在此研究的基础上提出提高网球运动知觉预判的合理化建议,从而快速提升运动员知觉预判的能力。

Adopting the high temporal resolution of ERP technology, this research compares the differences of the drive circuit perceptual anticipation of the behavioral and neural mechanisnl between the second-level athletes and novice group at different time points in the ball after landing （hitting racket and ball contact instantaneous time T2, T3） 80 ms after the shot time points. The behavior and ERP results showed a significant difference in perceptual anticipation between novice group and secondary players. Dipole localization found that T2 time point of slash anticipation induced N2 components and significantly activated the superior temporal gyrus. The above results show that the brain＇ s prefrontal cortex, temporal lobe, occipital lobe, parietal lobe are involved in the information processing related to the perceptual anticipation.
