“鞭打”动作是体育运动中常见的技术动作,为了掌握完成某一动作,常需要两臂(手)或两腿(足)具有尽可能大的运动速度,以达到增加动作的速度和力量,提高动作技术的质量,这些动作类似抽鞭子时的鞭打动作。如网球、排球、羽毛球等的扣球,投掷标枪和手榴弹,下肢的踢球,游泳中的打水动作等。目前对人体“鞭打”动作的力学原理大多用抽鞭子原理来阐述,抽鞭子时,先让臂带动 “Whipping” action is a common technical action in sports. In order to master the completion of a certain action, it usually needs two arms (hands) or two legs (feet) with the maximum possible speed so as to increase the speed and strength of the action. Improve the quality of motion techniques that are similar to whipping actions when whipping. Such as tennis, volleyball, badminton and so spike, throwing javelin and grenades, kick the lower limbs, swimming in the water action. At present, most of the mechanics of “whipping” the human body are described by the principle of whiplash. When whipping,
