Working up a sweat is a good thing when it comes to exercise, but being too hot may make you throw in your workout towel too soon. A study finds that holding a hand-cooling device while exercising may help obese women keep moving longer.
The small study, presented this week at the American Heart Assn.Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2012 Scientific Sessions in San Diego, examined the effects on various markers of health and fitness from holding a hand-cooling device during a workout.
Two dozen women ages 30 to 45 exercised three days a week for 12 weeks. Some held a palm-cooling device chilled to about 61 degrees during cardio portions of their workouts.
The others held the same device, but theirs was at normal body temperature, 98.6 degrees. All study participants worked toward exercising for 45-minute periods at 80% of their maximum heart rates.
