Instead, researchers have discovered, this so-called static stretching can lessen jumpers’ heights and sprinters’ speeds, without substantially reducing people’s chances of hurting themselves.
Now, two new studies are giving us additional reasons not to stretch.
One, a study being published this month in The Journal of Strength and Conditioning Research, concluded that if you stretch before you lift weights, you may find yourself feeling weaker and wobblier than you expect during your workout. Those findings join those of another new study from Croatia, a bogglingly comprehensive re-analysis of data from earlier experiments that was published in The Scandinavian Journal of Medicine and Science in Sports. Together, the studies augment a growing scientific consensus that pre-exercise stretching is generally unnecessary and likely counterproductive.
