Aerobic Exercise May Improve Insulin Use
Working out may do more than build muscles. A small study found that aerobic exercise increases blood vessel growth in muscle tissue and improves insulin sensitivity in people at high risk for type 2 diabetes. Insulin travels around the body in the circulatory system, so having more blood vessels means that insulin can better reach the body’s cells to lower blood glucose levels. In the study, 16 overweight or obese older adults with elevated blood glucose levels participated in a six-month exercise and weight-loss program. By the end, participants had more capillaries in their muscles than when they started out, which helped their bodies use their own insulin more effectively.
