其中一项发表在本月的《力量与训练研究杂志》(The Journal of Strength and Conditioning Research)上。研究称:假如你在举重前进行拉伸运动,你会感觉举的时候比预期力气更小、踉踉跄跄。此结果与另一项由克罗地亚科学家对以往实验进行的广泛深入的再次分析不谋而合,该项研究发表于《北欧医学与运动科学杂志》(The Scandinavian Journal of Medicine and Science in Sports)。这两项研究巩固了一个日益强大的科学共识:通常情况下,在锻炼前做拉伸不仅没必要,还可能起反作用。
Many issues related to exercise and stretching have remained unresolved. In particular, it is unclear to what extent, precisely, subsequent workouts are changed when you stretch beforehand, as well as whether all types of physical activity are similarly affected.
锻炼与拉伸之间的很多关联尚不明朗。特别是:人们不知道准确来说,拉伸到什么程度会使接下来的锻炼受到影响;也不知道是否锻炼前拉伸对一切体育活动都产生相似作用。
For the more wide-ranging of the new studies, and to partially fill that knowledge gap, researchers at the University of Zagreb began combing through hundreds of earlier experiments in which volunteers stretched and then jumped, dunked, sprinted, lifted or otherwise had their muscular strength and power tested. For their purposes, the Croatian researchers wanted studies that used only static stretching as an exclusive warm-up; they excluded past experiments in which people stretched but also jogged or otherwise actively warmed up before their exercise session.
