A study finds that holding a hand-cooling device while exercising may help obese women keep moving longer.
The small study, presented at the American Heart Association 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 parts 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 percent of their maximum heart rates.
During the three months, the group that held the cooling device cut an average of five minutes off their time during a 1.5-mile walk, reduced their waist size by an average of almost three inches, lowered their resting blood pressure and increased their exercise heart rate. Those in the control group saw no significant changes.
