摘要：走運動鍛練度及び走能力に差のある3名の被検者を対象に,走速度の増加にともなう下肢の各関節の動きの変化をelectrogoniometerで,また左右脚の地面との運動関係を運動靴に充填した面圧計で同時に記録し,その記録の分析により次のような結論を得た. (1)走速度の増加にともなって股関節,膝関節の運動範囲は鍛練度,走能力の差にかかわらず大きくなる.しかし,同一走速度条件では鍛練者が非鍛練者よりその運動範囲が大きくなる. (2)接地瞬間時の接地脚大腿と振り出し脚大腿の相対的位置は,鍛練者ほど振り出し脚大腿が接地脚大腿に近づいている.また離地瞬間時では,鍛練者は非鍛練者より振り出し脚大腿をより前方ヘ高く振り出している. (3)非鍛練者が鍛練者より振り出し脚の動きが遅れていることから,より高い走速度に適応するためには早い振り出し動作が必要であるといってよい.
其他摘要：The purpose of this study was to analyze the motion pattern for the hip, knee and ankle joint during running at various speeds. The electrogoniometer was used to obtain continuous recordings of the rotation of the joint and the pressure transducer fixed on the inside of the shoes was used to obtain the reference points for running. Those points were the instant when the heel made contact with the ground, the instant the toe exerted the maximum force against the ground and the instant the the broke the contact with the ground. Three subjects (who were an excellent sprinter, a good runner and an untrained of ordinary adult) were employed in this study. They run at various speeds on the motordriven treadmill, the speed of which was from 150m/min to 500m/min. Results obtained in the study were as follows; 1.The amplitude of the rotation of the hip and the knee joint tended to increase according to the increase of running speed. The increasing rate of the amplitude was larger for the trained subject than for the untrained. 2.When the trained subject striked his foot on the ground, the swing leg was carried more nearly towards the support leg even at lower speed of running. On the contrary, the untrained subject remained his swing leg behind the body at the same instant. 3. At the instant when the toe exerted the maximum force against the ground, the trained subject carried his knee joint of the swing leg upward in front of mid body. But the untrained subject kept his swing leg near the support leg.
