Exercise Alone Improves Insulin Sensitivity

Exercise Alone Improves Insulin Sensitivity. A moderate aerobic exercise program, without weight loss, can improve insulin sensitivity in both lean and obese sedentary adolescents, according to a new study. In this study, 29 adolescents completed the 12-week moderate aerobic exercise program. The goal of each exercise session was to get the participants' heart rate to increase to at least 70 percent of their maximum capacity. The findings show that exercise alone can increase fitness and improve insulin sensitivity, making an aerobic program like the one used in this study a potential useful tool in preventing obesity-related illnesses. JCEM, Nov 2009
