(BSNS WIRE) ADVANCE/Stretching Not Useful During Sports Warmup But Crucial During Cooldown:
Physiologist

(ADVANCE) NEW YORK--(BUSINESS WIRE)--Nov. 30, 1998--Contrary to
traditional wisdom, stretching is not useful for preventing injuries
during a sports warmup, but it is crucial during cooldown, asserts a
Baylor University Medical Center exercise physiologist. Robert Vaughan, Ph.D., states in the current (December/January) issue of New Choices: Living Even Better After 50, that "in tennis or running, for example, your calf muscles contract a bit each time your foot hits the ground," he says. "So after a tennis match or a long run, those muscles have tightened up quite a lot." Muscles that were not loosened by stretching will stay tight and pull where they connect to the bone -- at the tendons -- and that can result in tendinitis.
Warming up and cooling down are critical components in avoiding sports injuries, according to Major Becky McCollam, of the U.S. Army's
Physical Fitness Research Institute.
"To avoid injury, you must prepare your body for exercise, and the best way is to warm up adequately. But too many people don't take the time to do so," she suggests. As you exercise, blood flows to the working muscles, explains Vaughan. "If you run a 10-kilometer race and then get in the car and drive home, you may feel faint because blood has pooled in the leg muscles and not enough is available to your brain," he notes in New Choices. "It's important to keep moving for 10 or 15 minutes after a workout so that the movement of your muscles can help redistribute blood to the rest of the body."
