| 摘 要： | 研究人体在运动过程中,肌肉长度、肌长度变化速率、肌力臂等肌肉功能参数以及肌肉功能的动态变化,是运动生物力学、运动解剖学、运动生理学和体育训练学等学科领域中十分关注的课题,它们对于深入探讨人体运动规律、肌肉的神经控制与工作特性以及制定肌肉专项力量训练方案等均具有非常重要的理论和实践意义.为此,本文将以人体下肢肌肉附着点(肌肉起止点、代起止点)、关节转动中心在相应环节基准坐标系中的坐标为基础,建立适合于活体应用的下肢肌肉功能模型.该模型不但能详尽地定量评定下肢于不同状态下肌肉所具有的潜在功能,而且也能获得人体在运动过程中下肢肌肉功能参数的动态变化状况.同时,本研究通过步态分析的实例,初步检验了模型的可用性和可靠性.

| Abstract: | Wide attention has been drawn in the research field of sports biomechanics, sports anatomy,sports physiology and athletic training to study the changes of kinematics and kinetics of the muscularwork state during exercise, such as muscular length, its variable velocity and the arm of muscularforce. It will help greatly not only in probing into the law of movement, muscular working characteristicsand nerve controlling, but also in preparing the program for muscular strength training. For this purpose,a muscular function model of the lower extremities has been developed based on the coordinates ofmuscle attachments of lower extremities (mark of muscles origins and terminations) and coordinatesof joint turning center in the corresponding benchmark coordinates system of segments. The muscularfunction model can be used not only to rationally assess the muscles, potential enginery of lower limbsin different state, but also to provide dynamic changes in function parameter of lower limbs during bodymovement. At the same time, the article makes a sample of gait analysis, preliminarily testing theusability and reliability of the model. |
