中文摘要:

本实验利用人为强化本体感受反馈的原理探讨一种新的加速运动技能获得的方法。实验参加者在电脑屏幕前用鼠标追踪电脑屏幕上一个移动的光点，移动光点按预定的程序作曲线运动。另一子程序按每秒一百次的频率自动扫描移动光点与追踪鼠标点之间的距离，每轮追踪结束后自动计算出该轮扫描误差的标准差。移动光点与追踪鼠标点之间的距离越小，追踪误差越小。随着练习次数及练习天数的增加，追踪误差会越来越小。我们发现，在保证运动连续性的条件下最大限度地增强与运动相关的主动肌、对抗肌、协同肌及支持肌自身紧张度可以加速运动技能的获得。

英文摘要:

This experiment focuses on a new method of accelerating the acquisition of sport skills by increasing tension to one's own movement-related muscles. The subject used a cursor to track a moving spot, which made pre-designed curve movement on computer screen. A program scanned and automatically calculated the distances between the moving spot and the tracking cursor at 100 times per second. RMSE (root mean square error) was automatically calculated after each track. The smaller the RMSE is, the more skillful the tracking will be. RMSE will be smaller and smaller following the increase of the practice. It is discovered that the acquisition of sport skills can be accelerated by purposely enhancing the tension of movement-related muscles such as active muscles, confrontation muscles, collaborative muscles and support muscles.
