Development of computerized support system for swimming coach

许多运动员使用一些心率监测设备进行训练。然而，游泳者在游泳时无法确定自己的心率。因此，教练必须基于遥测心率监测器来控制运动强度水平。为了给游泳教练员提供有效的生理和运动学数据，需要一个计算机化的支持系统。计算机化系统包括收集、分析和呈现功能。本研究旨在开发一套游泳教练员电脑辅助系统。该信号是V-FM转换和传输。沿池边沿着每隔10 m设置接收器天线。信号被一个增强器放大并连接到接收器。在项目初期，信号通过A/D转换板传输到PC机控制Lab View。目前，改进了用于实际使用的产品。将模拟信号转换为块脉冲。脉搏通过RS-232 C串口传输到PC机，由Visual Basic控制，监测软件包括10 m sec手表、心率显示器、每搏率显示器、单圈时间表、数据保存功能和心率波动图。

Many athletes use some heart rate monitoring devices for training. However, Swimmer can not make sure of own heart rate during swimming. Therefore, the coach has to control the intensity level for exercise based on the telemetry heart rate monitor. A computerized support system is necessary to give effective physiological and kinetic data for swimming coach. The computerized system includes functions a collection, an analysis and a presentation functions. The purpose of this research was to develop of a computerized support system for swimming coach (CSSSC).Heart rate got from HR sensor (POLAR ELECTRO). The signal was V-FM converted and transmitted. Antennas for receiver were set along pool side each 10m interval. The signal was amplified by a booster and connected to receiver. While the early stage of this project, the signal ran through A/D transform board to PC controlled Lab View. Presently, a product for practical use was improved. The analog signal transferred to a block pulse. The pulse ran through RS-232C to PC controlled Visual Basic.The monitoring software included 10m sec watch, heart rate indicator, stroke rate indicator, list of lap time, function of data saving and a graph of heart rate fluctuation.
