自由泳是竞技游泳中速度最快的一种姿势,游泳竞赛规则规定,自由泳比赛中可采用任何一种姿势。在游泳运动竞赛中,自由泳的比赛项目最多,在奥林匹克运动会游泳比赛项目中仅自由泳比赛项目就有16项。因此,自由泳在游泳竞赛中是最重要的项目,一个国家的游泳运动水平高低,往往以该国家的自由泳水平高低为标准。自由泳在整个游泳比赛中所占比重非常大,各个国家对自由泳技术非常重视。本文将数学分析与自由泳技术的各阶段动作相融合,用数学分析的方式将自由泳技术量化分析。 Freestyle swimming is the fastest form of competitive swimming, swimming competition rules, freestyle swimming can be used in any kind of posture. In swimming competitions, freestyle has the largest number of competitions, and there are 16 freestyle competitions in the Olympic Games swimming competition. Therefore, freestyle swimming contest is the most important project, a country’s swimming level, often in the country’s freestyle level as the standard. Freestyle swims in the entire proportion of the game is very large, all countries attach great importance to freestyle technology. In this paper, we combine the mathematical analysis with the various steps of freestyle technique, and quantify the freestyle technique by mathematical analysis.
