Minimal EXERCISE Thwarts DIABETES

A recent study reported online in BMC Endocrine Disorders looked at exercise and diabetes parameter in healthy volunteers. Specifically, researchers wanted to find out the impact of short high intensity workouts on insulin sensitivity. Over time and with poor diet and sedentary lifestyles, we become more resistant to insulin, a hormone designed to lower our blood sugar. Resistance to insulin can produce type II diabetes. On the other hand, having high insulin sensitivity is seen as protective from developing diabetes.

In this study, healthy male volunteers with a median age were recruited to participate in a trial period of high-intensity exercise. Over two weeks, participants completed six sessions of high-intensity interval training consisting of four to six 30-second sprints on a stationary bike.

At the end of the study, insulin sensitivity of the subjects improved by 23% with this small amount of exercise. Researchers conclude that more studies should be done to verify these results.
