近期生物科学与运动科学的研究使拉伸活动与损伤预防相关的假说受到了挑战。有位跳远运动员做赛前准备活动时,拉伸大腿肌肉花了很长的时间。在准备性试跳时,他感到自己左腿股四头肌有些僵硬(以右脚为起跳脚)。他认为可能是对其拉伸的量还不够,又想起了教练与医师传授的关于如何消除肌肉僵硬的方法,于是对股四头肌进行了额外的拉伸。然而,在首次试跳的起跳阶段, 损伤发生了。在左腿向上摆时,他感到股四头肌剧烈疼痛,这使他放弃了本次试跳以及整个比赛。 Recent studies in the biological sciences and sports science have challenged the hypothesis that stretching activity is associated with injury prevention. It took a long time for a long jumper to stretch his thigh muscles when he was doing pregame preparations. He was feeling stiff on his left leg quadriceps (with his right foot as the starting leg) during the pre-trial jump. He thought it was probably not enough to stretch it, and he remembered the coaching and physician’s teachings on how to get rid of muscle stiffness and stretched the quadriceps extra. However, damage occurred during the first take-off. He felt the severe pain in the quadriceps when he was swinging up his left leg, which led him to abandon the test run and the entire match.
