冬季运动项目训练智能管理系统

Intelligent management system for winter sports training

为了准确、定量、高效地测量和分析冬季项目运动员的专项动作,开发了冬季运动项目训练智能管理系统。该系统包含动作捕捉和识别、地面反力检测和计算以及人体动力学分析3个子系统,能够综合分析专项动作的运动学、动力学和骨骼肌肉力学状态。使用Python语言编制的系统软件集成了上述功能,利用此软件对一组跳台滑雪起跳动作进行了模拟计算,验证了系统的可靠性。该系统可同时应用于科研和教学,不仅能够为运动员的专项动作科学化训练提供指导,也可在课程教学中帮助学生学习运动生物力学的测量和分析技术。

In order to accurately,quantitatively and efficiently measure and analyze athletes’special actions in winter sports,an intelligent management system for winter sports training is developed.The system includes three sub-systems,i.e.motion capture and recognition,ground reaction detection and calculation,and dynamics analysis of human body.It can comprehensively analyze the kinematics,dynamics,and musculoskeletal mechanics of special actions.The above functions are integrated into a software system programmed with Python,and the reliability of the system is verified by a simulation on a group of ski jumping taking-off.The system can be applied to scientific research and teaching at the same time,it can not only provide guidance for the scientific training of athletes’special movements,but also help students learn the measurement and analysis technology of sports biomechanics in course teaching.
