凡经过生物力学分析的所有运动技术中,很少有比短距离起跑技术分析得更透彻的了。发令员发出“各就位”口令时,运动员走上前去,两手分开同肩宽,放在起跑线后,两脚接触地面和起跑器,后腿膝部贴着地面(图1)。“予备”,后腿膝部抬离地而,抬高臀部使重心前移(图1中 b)最后,鸣枪时,手离开地面,两臂有力地摆动(一向前,一向后),同时有力地伸展两腿推动身体向前。离开起跑器并进入了跑的 Few of all the kinetic techniques biomechanically analyzed are more thorough than the sprint technique. When the starter issued the “all in place” password, the athlete walked up and both hands were separated from each other by the shoulder width. After resting on the starting line, both feet touched the ground and the starting block, and the hind legs lapped against the ground (Figure 1). “Prepare” the knee of the hind leg to lift away from the ground, raise the buttocks to move the center of gravity forward (b in Figure 1) Finally, when the gun is fired, the hand leaves the ground with both arms vigorously swinging (forward and backward) At the same time vigorously stretch legs to promote the body forward. Leave the starting block and enter the running
