In the present study, we aimed to determine whether response training shortens visuo-motor related time in athletes performing a simple reaction task. 14 healthy male athletes were included in the study. Subjects were randomly divided into 2 groups: a training group, which underwent response training consisting of a mastication task in response to a visual signal, and a non-training (control) group, which did not undergo response training. Pre-motor time and transcranial magnetic stimulation over the primary motor cortex for recording motor evoked potentials were measured in the control group, and before and after the response training session in the training group. Both pre-motor time and visuo-motor related time, but not motor evoked potential latency, were significantly reduced after response training in the training group. Subjects who had a longer visuo-motor related time before training showed a greater reduction in visuo-motor related time after training. These results suggest that visuo-motor related time before training could be useful as a predictor of the reduction in reaction time following response training.
在本研究中，我们旨在确定反应训练是否会缩短运动员在执行简单反应任务时的视觉运动相关时间。本研究纳入了 14 名健康男性运动员。受试者被随机分为 2 组：训练组，进行咀嚼任务以响应视觉信号的反应训练；非训练（对照组），不进行反应训练。在对照组中测量预运动时间和经颅磁刺激初级运动皮层以记录运动诱发电位，在训练组中测量反应训练前后的预运动时间和视觉运动相关时间。仅在训练组中，预运动时间和视觉运动相关时间（但不是运动诱发电位潜伏期）在反应训练后显著降低。在训练前视觉运动相关时间较长的受试者，在训练后其视觉运动相关时间的降低幅度更大。这些结果表明，训练前的视觉运动相关时间可作为反应训练后反应时间减少的预测指标。
