| 摘 要： | 研究目的是研制一套快速反馈系统,用于测试和分析赛艇技术的生物力学参数。本系统于1989年研制成功,它由无线电发射机、无线电接收机、传感器、同步器及其相应软件组成。系统有6个通道,用以同步测量:作用于桨环上的力,桨在水平面内的角位移,艇加速度,运动心率。系统的采样频率为50Hz,有效遥测距离大干500米。系统软件能在几分钟内计算出50多个技术参数,给出统计结果,并能根据运动员不同的技术模式对桨入水角进行优化。

| Abstract: | A telemetry system for evaluation and improving rowing techniques was designed and applied with success.The func-tion of the system is as follows:1.Six channels in the system can measure the force applied to the swivels,the angular displacement of oars in horizon-tal plane,the horizontal acceleration of boat,and the heart rate of rower.2.The effective measuring distance is at least 500m and the sampling frequency is 50Hz.The computer screen can si-multaneously show all the information received.3.The system has a powerful ability to store and process the information.More than 50 important technique indicescan be derived.4.The system can make statistical evaluation of six direct measured parameters and many other derived parameters.Optimization of oar angle at entry can be achieved.5.The high-speed camera and video recorder can be used with the system synchronously by means of the synchronizer. |
