Study Of Tachiwaza In Jodo By Examining Pysiological And Visual Data

本文对运动生理学进行了研究。本研究以柔道运动员采用立抛战术时的动作为研究对象，利用中野等人设计的SN型物理运动追踪分析仪（PLPA）和上肢肌电记录，收集三维运动所需的信息，并通过同时记录的动作数据，研究这两种数据源之间的关系。本研究选取了四种立投战术：大正、，并将被试分为两组，即柔道运动员组和非柔道运动员组。运动员。从数据中观察到，经过训练的柔道运动员动作更迅速，腰部运动更流畅，肌肉使用更合理，圆周动作的中心始终位于体内。与此相反，未经训练的柔道运动员腰部运动较差，肌肉使用不合理。迄今为止，在同一张图上研究生理电脉冲和运动运动的工作很少，但本研究表明这是可能的，结果是有用的。希望今后能改进PLPA方法，以产生更清晰的结果。

This paper deals with an investigation into the Physiology of excercise. The movement studied was that of Judo players when applying standing throw tactics.The information needed to examine three-dimensional locomotion was gathered by using a SN type physical Locomotion Pursuit Analyser(PLPA)devised by Nakano et al. and from electromyogram recordings of the upper extremities.The relationships between these two sources of data were examined with the help of a simultaneously recorded data of the movements. In this study the four tactics of Tachi-waza(standing throw), namely Ohsotogari, Deashibarai, Kouchigarin, Ohuchigari, were selected.The participants in the study were divided into two groups, trained judo players and untrained judo. players.It was observed from the data that trained judo players acted more rapidly, had smoother waist motion, used their muscles more rationally and always located the center of circular action within their body. By contrast the untrained judo players had poor waist motion and showed irrational muscle use.So far very little work has been carried out to study physiological electric impulses and movement of excercise on the same graph paper, but this study shows that it is possible and the results are useful.In the future it is hoped that the PLPA method can be improved in order to produce even clearer results.
