我国重大游泳比赛技术参数采集与分析系统的应用研究

Applied study of technique parameters collecting and analyzing system for important swimming competition in China

游泳比赛可划分为几个既相互独立又相互联系的部分,各个部分的特征用不同的技术参数来表示,反映运动员在比赛中的技术、战术情况。研究采用文献资料、比赛现场技术参数采集、图像解析和数据分析等,对我国重大游泳比赛的技术参数进行采集和分析。研究认为我国除个别尖子运动员外,多数运动员存在出发反应时长、出发速度慢,转身速度慢、技术细节不完善、比赛节奏不稳定等问题,反映出我国运动员的技术还需要进一步完善和提高。

Swimming competition can be divided in to several isolated and correlative parts, whose features denoted with different technique data, reflect the swimmers＇ techniques and strategies in the competition. By the methods of documentation, technique parameters collected on the spot of the competition, image analysis and data analysis, the technique parameters of important swimming competitions in China were analyzed. According to the research, except for a few elite ones, most swimmers had weaknesses in techniques, such as slow reaction to the start signal, slow speed in starting and returning, imperfect technique aspects and unsteady swimming rhythm, which needed improving and perfecting.
