Gretchen Reynolds of the NY Times Well Blog posted another article today about stretching. If you read my post about her interview on NPR last year, you know I don’t agree with her stance on stretching. Well, she’s at it again with more evidence to back her case.
The crux of the argument is in this paragraph where she summarizes the findings of some studies recently done on pre-activity static stretching:
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.
