Standing throw PLPA Judo players movement study

项目摘要

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.

本文涉及运动生理学的研究。研究的运动是柔道运动员应用站立投掷战术时的运动。通过使用 Nakano 等人设计的 SN 型物理运动追踪分析仪（PLPA）来收集检查三维运动所需的信息。借助同时记录的运动数据来检查这两个数据源之间的关系。在这项研究中，选择了立式投掷的四种战术，即Ohsotogari、Deashibarai、Kouchigarin、Ohuchigari。研究的参与者分为两组，受过训练的柔道运动员和未经训练的柔道运动员。从数据中观察到，经过训练的柔道运动员动作更加迅速，腰部动作更加流畅，肌肉运用更加合理，并且始终位于身体内圆周动作的中心。相比之下，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，在同一张方格纸上研究生理电脉冲和运动动作的工作还很少，但这项研究表明这是可能的，而且结果是有用的。未来希望PLPA方法能够得到改进，以产生更清晰的结果。
