According to the application requirement in sports training, a new athletic training system is designed by taking advantage of wireless sensor network technologies. It is composed of the embedded data gathering terminal and the database server. Designed with sensor nodes and base stations, the hardware can examine the real-time acquisition of the movement parameters of athletes. Meanwhile, nodes, based station controlling and data management software is designed, realizing its functions of data receiving, data storing and analyzing. Through system experiment, the result indicates that athletic training system meets the sports training need and provide an effective research tool for making scientific training program.
