摘要
以自行研制的动态阻力测试仪器探索了一种测量动态阻力的实验方法。通过蛙泳收腿动作划分2阶段的测试和计算后指出:动态阻力受速度的变化影响较小;在较高运动速度下静态阻力占总阻力的比例稍高;动态阻力占总阻力的比例随运动速度的下降而提高。
This paper pursues an experimental study of active drag(AD) measurement,which is tested through the AD measurement equipment made by ourselves.After the test and calculation of 2 divisions of the phase of breaststroke recovery,it shows that there is little connection between active drag and speed;while the passive drag accounts for a higher percentage of the total drag when the player swims at a high velocity;with the speed descending the active drag gradually increases.
