为了让新研究涉及范围更广,同时解释上述问题,克罗地亚萨格勒布大学(University of Zagreb)的科学家梳理了上百个以前进行过的实验。这些实验中,志愿者先做拉伸运动,然后或跳、或扣篮、或举重或进行肌肉强度与力量测试。基于研究目的,他们只选择用静态拉伸作为唯一热身运动的实验;剔除了那些让志愿者在锻炼前除拉伸外还慢跑过或做过其他动态热身的实验。
The scientists wound up with 104 past studies that met their criteria. Then they amalgamated those studies' results and, using sophisticated statistical calculations, determined just how much stretching impeded subsequent performance.
最后,符合他们选择标准的共有104项研究。他们综合这些研究的结果,利用复杂的统计计算方法确定拉伸对锻炼的影响程度。
The numbers, especially for competitive athletes, are sobering. According to their calculations, static stretching reduces strength in the stretched muscles by almost 5.5 percent, with the impact increasing in people who hold individual stretches for 90 seconds or more. While the effect is reduced somewhat when people's stretches last less than 45 seconds, stretched muscles are, in general, substantially less strong.
统计数字——尤其是对于竞技型运动员的数字——发人深省。计算结果是:静态拉伸让拉伸后的肌肉强度下降约5.5%;进行过90秒以上拉伸活动的人下降程度更大;若短于45秒,则影响减轻。总体而言,拉伸过的肌肉强度普遍减弱。
