以往测量游泳阻力大多采用被动地在水中拖曳游泳者的方式,对主动游泳者所受阻力只有一些间接的估测值。本文试图通过直接测量运动者的推进力来估测阻力值,其根据是:当游泳者匀速地主动推进时,在某一时间段内所受的平均阻力等于其平 In the past, the most common measure of swimming resistance was the passive way of dragging swimmers in the water, with only some indirect estimates of the resistance of active swimmers. This article attempts to estimate the resistance value by directly measuring the athlete’s propulsive force based on the fact that when the swimmer is actively propelled at a constant speed, the average resistance experienced by the swimmer for a certain period of time is equal to the average
