High-Intensity Exercise Bursts Improve A1C

As a way of exercising to control your type 2 diabetes, try something new: high-intensity bursts with short breaks in between. In a study, 14 people with type 2 diabetes performed three high-intensity cycling sessions per week. Using a stationary bike, they rode hard for up to four minutes, rested for three minutes, then repeated the cycle five times in a row. Another 14 patients continued their usual exercise and eating plans. After 12 weeks, the high-intensity exercise group had lowered its average A1C—a measure of glucose control—from 7.1 to 6.8 percent. High-intensity exercisers also saw improvements in heart structure and function, reductions in body fat, and a 39 percent reduction in liver fat compared with the other group—all without making dietary changes during the study.
