When it comes to boosting your mood, exercise is the gift that keeps on giving and giving.FRIDAY, May 29 (HealthDay News) — When it comes to boosting your mood, exercise is the gift that keeps on giving and giving, new research suggests.

In fact, the feel-good afterglow a workout brings may last far beyond the hour or so that’s been previously assumed.

"“Moderate intensity aerobic exercise improves mood immediately and those improvements can last up to 12 hours,” concluded study lead researcher Dr. Jeremy Sibold, assistant professor of rehabilitation and movement science at the University of Vermont, Burlington.
The findings were presented this week at the annual meeting of the American College of Sports Medicine in Seattle.

Other studies have found a mood-boosting effect to exercise. But the other research hadn’t tracked the effect for as long as Sibold and his team did. “This is one of the few studies that actually looked at a much longer window, 24 hours,” he said. “The question I was interested in was, ‘How long does that feel-good effect, that improvement, last?’”

To find out, Sibold and co-author Kathy Berg randomly assigned 48 healthy men and women to a control group that did not exercise, or to a group that did exercise. The participants ranged from 18 to 25 years old. At the start of the study, all participants completed a standard survey of mood. The exercisers then rode on a stationary bike for 20 minutes at moderate intensity.

All participants then repeated the mood survey at one, two, four, eight, 12 and 24 hours later."
