No Harm In Stretching Yourself

The Sporting Life


Static Stretching: What was once old is new again, Reynolds writes for the NYT: “For generations, gym students were taught to stretch before working out or playing games. Then the practice fell out of favor: Studies seemed to show that such ‘‘static’’ stretching (holding a pose for anywhere from a few seconds to several minutes) temporarily reduces muscular power, weakens athletic performance and increases the risk of injury. So most fitness experts currently advise against static stretches before exercise. But now a comprehensive new review of decades’ worth of research indicates that they might not be such a bad idea after all.”

An article, by Gretchen Reynolds, in The New York Times says that stretching before engaging in an athletic activity is OK once again; this comes after recent findings said it was bad for athletic performance. This proves the adage that what was once good for you, then bad for you, is again good for you, just like the consumption of butter, eggs and coffee.

In “The Right Way to Stretch” (June 21, 2016), Reynolds writes:
This month, the journal Applied Physiology, Nutrition and Metabolism published a study by four distinguished exercise scientists who analyzed more than 200 studies of how stretching affects subsequent exercise. (The authors had conducted some of these studies themselves.) In broad terms, they found that static stretching can briefly inhibit the ability to generate power. So if you reach for your toes and hold that position, tautening your hamstrings, you might not then be able to leap as high or start a sprint as forcefully as if you hadn’t stretched.
Those undesirable effects were generally found, however, only if each stretch was held for more than 60 seconds and the subject then immediately became fully active, with no further warm-up. Those are hardly real-world conditions, says Malachy McHugh, the director of research at the Nicholas Institute of Sports Medicine and Athletic Trauma at Lenox Hill Hospital in New York, who is the study’s co-author. Outside the lab, he says, most people are unlikely to hold a warm-up stretch for longer than about 30 seconds. The review found few lingering negative impacts from these short stretches, especially if the volunteers followed that stretching with several minutes of jogging or other basic warm-up movements. In fact, these short static stretches turned out to have a positive correlation. People who stretched in this way for at least five minutes during a warm-up were significantly less likely to strain or tear a muscle subsequently.
I don’t always listen to the latest medical and health research findings. so I continued to do static stretches, even though I had read a while back that it was no longer advisable. Now I can continue stretching—guilt-free—without the gnawing feeling that it has been bad for me all along, that it has done irreparable harm to this 58-year-old body. Alas, there is no harm in stretching yourself.

Happy workouts, everyone.
