The purpose of this study is trying to make a comprehensive study by making the mathematical modd of the loiter extremity and the locus change of the center gravity of human body during the takeing-off in different postures and measuring the electromyography of the major muscles of the louer extremity and taking the vertical jump take-off as an excomple. So that theybrought to light the intermal law and provided a biomschanical basis for physical education,Sport training and Selecting athletes. The subjects (10 male athletes aged 20) have been measured and recorded major muscles of the louer extremity using JTI-electromygraph, Beside the novement of the vertical jump was filmed by a BOLEX camera at a sampling rate of 64fts. The center fibmed were entered into a computer for measuririg by using a Film Motion Analyer.We also analyzed with mathematical model. The results of study indicated that there is consistency between the analysis of the mathematical modd of lower extremity and the result which is from the expriment. The lengh of the lower extremity, especially the legs are langer which is mort adwontageus.It is to the height of the take-off. This can be used as one of Target of Selecting athletes The major muscular activities of the lauer extremity are in an orderly and additional way.

本文研究的目的是通过下肢数理模型,不同姿势起跳人体重心轨迹变化、下肢主要肌肉肌电活动以原地纵跳为例进行综合性研究.揭示其内在规律,为体育教育、运动训练、选才提供生物力学基础.研究对象为10名男性运动员,年龄为20岁,用JTI—肌电仪测定下肢肌肉的肌电,用Bolex摄影机以每秒64幅频率拍摄原地起跳动作.人体重心用影片解析仪通过计算机计算并对下肢进行数理模型分析.研究结果表明①下肢活动的数理模型与实验结果有一致性;②下肢长度特别小腿长度较长有利跳起高度,这可作为选才指标之一;③下肢主要肌肉活动是有序和叠加活动方式.

By using the method of high speed camera, the author analyzes the high speed technical velocity characteristics of male race walker majoring in 20 km event in 4 th city games. The result shows that the rising pattern of body center gravity velocity for Chinese elite race walker is significantly different. Under the high speed walking, the high quality of movement of swing leg is more important than the degree of foot's driving. It is suggested to increase the muscle strength in hip joint.

运用高速摄影等方法 ,对第 4届城市运动会男子 2 0 km竞走运动员的高速走技术的速度特征进行分析研究。结果表明 ,我国优秀竞走运动员重心速度回升的方式明显不同 ,在高速走时 ,高质量的摆腿动作比蹬地的用力程度更为重要。建议运动员增加髋关节肌群的力量练习。

After trake - off, the center gravity of Fosbury - flop follows a fixed path - As the c. g travels along the parabola , the body should rotate around the c g. in a way that will allow the clearance of a bar set as high as possible. The rotation consists of a "twist"(longitudinal axis of the body)which turns the back of the jumper toward the bar, and a "somersault" (transverse axis) which leads to a face - up layout position at the peak of the jump. To a great extent ,the combination of these two motions...

After trake - off, the center gravity of Fosbury - flop follows a fixed path - As the c. g travels along the parabola , the body should rotate around the c g. in a way that will allow the clearance of a bar set as high as possible. The rotation consists of a "twist"(longitudinal axis of the body)which turns the back of the jumper toward the bar, and a "somersault" (transverse axis) which leads to a face - up layout position at the peak of the jump. To a great extent ,the combination of these two motions of the body that makes us have a clear concept of the angular momentum and how it affects the rotation produced by the angular momentum.

背越式跳高至起跳开始,身体重心沿着起跳角形成的固定抛物轨迹运行,身体围绕自身的轨迹旋转达到尽可能的高度在旋转过程中,经纵轴的背对横杆和水平轴的面部朝上,身体绕两个轴线动作的扭转过杆,结合助跑的水平速度与两个轴线的身体动作,在某种程度上我们要应有个清楚的概念,身体扭旋过杆是由角动量产生的和角动量的形成又如何影响着身体的扭旋.
