They also are less powerful, with power being a measure of the muscle's ability to produce force during contractions, according to Goran Markovic, a professor of kinesiology at the University of Zagreb and the study's senior author. In Dr. Markovic and his colleagues' re-analysis of past data, they determined that muscle power generally falls by about 2 percent after stretching.
同时,肌肉的力量也会变差。该研究的通讯作者、萨格勒布大学运动学教授葛兰·马尔科维奇(Goran Markovic)将肌肉力量解释为肌肉收缩时产生力量的能力。他与同事对过去实验的再分析得出结论:拉伸后,肌肉力量降低约2%。
And as a result, they found, explosive muscular performance also drops off significantly, by as much as 2.8 percent. That means that someone trying to burst from the starting blocks, blast out a ballistic first tennis serve, clean and jerk a laden barbell, block a basketball shot, or even tick off a fleet opening mile in a marathon will be ill served by stretching first. Their performance after warming up with stretching is likely to be worse than if they hadn't warmed up at all.
还有一个结果是:肌肉的爆发力亦显著降低——最高可达2.8%。也就是说,想从起跑线上立即起跑、将网球猛击出去、挺举杠铃、篮下盖帽、飞奔过马拉松第一程的人,都被拉伸“坑苦了”。他们以拉伸运动来热身比完全不热身表现得差。
