女游泳运动员戴划手掌时自由泳手臂动作变化的运动学分析

Kinematic Analysis of Pulling with Paddle in Female Freestyle Swimming

用定量的运动学方法对13名女子一级以上游泳运动员徒手和戴两种不同规格的划手掌游自由泳时的划水技术进行分析比较，指出了女运动员戴划手掌游时划水技术动作在时间、空间、时空方面与原有技术动作相比较发生的一些显著改变，建议教练员和运动员在使用划手掌进行水中专项力量训练时重视避免划水动作结构和节奏方面的变化，将戴划手掌游对技术动作的破坏减小到最低程度。

Quantitative kinematic analysis was made on the pulling technique of 13 elite female swimmers when swimming in freestyle with and without paddles. It was found that pulling with paddles could bring about some significant changes in time, displacement and velocity of swimming technique. To avoid the unfavourable influence of pulling with paddles to technique as far as possible, the study suggested coaches and swimmers pay attention to the alteration of structure and rhythm of pulling when using paddles for specific weight training.
