| 摘 要： | 目前,田径项目运动生物力学研究的主要方法是采用高速影像解析系统监控训练过程,通过专用或通用解析软件获得运动学信息。为提高训练效率,及时纠正技术动作的缺陷,教练员迫切需要一种能够在训练过程中及时反馈运动信息的设备。针对这一现状,在充分凝炼项目需求基础上,提出了一种基于数字跑道的田径训练信息采集和反馈系统。该系统采用柔性阵列传感器获取助跑过程中的接触交互信息,采用专用解析软件集成化处理运动学参数,实时提供运动过程中的步长、速度、步频、起跳力等运动生物力学参数。该系统实现了运动表象与内在力学因素的综合分析,有利于教练员、运动员深入把握项目内在规律。通过在国家田径队跳远项目运动员的测试使用,其有效性和科学性得到了初步验证。 |

| Abstract: | At present,scientific track and field training is mainly using high-speed image analysis system to access the kinematics information of training process.To improve training efficiency and correct technical deficiencies betimes,coaches need an equipment to provide real-time kinematics information in training courses.In view of this problem and full consideration on the basis of this project,the kinematics information collecting system based on digital course is introduced.Flexible array sensors are used to access inter-contact information,as well as using self-developed professional analytical software to process these kinematics parameters,which can provide several bio-mechanical parameters real-timely.The system realizes the integrated analysis of campaign appearance and internal mechanical factors.It is favor for coaches and athletes to grasp the inherent law of the sport project.Through the long-term use and test in national long jump team,its effectiveness and scientific have been primarily verified. |
