Study Of Tachiwaza In Jodo By Examining Pysiological And Visual Data

本文对运动生理学进行了研究。研究的动作是柔道运动员在运用立掷战术时的动作。使用Nakano等人设计的SN型物理运动追踪分析仪（PLPA）和上肢肌电图记录收集三维运动所需的信息。这两个数据来源之间的关系是在同时记录的运动数据的帮助下进行检查的。本研究选取了立掷的四种战术，即大投加里（Ohsotogari）、Deashibarai、Kouchigarin、Ohuchigari。研究的参与者被分为两组，训练有素的柔道运动员和未经训练的柔道运动员。的球员。从数据中观察到，训练有素的柔道运动员动作更快，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身体内部。相比之下，未经训练的柔道运动员腰部运动差，肌肉使用不合理。到目前为止，在同一张坐标纸上研究生理电脉冲和运动运动的工作很少，但这项研究表明，这是可能的，结果是有用的。在未来，希望PLPA方法可以得到改进，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.
