High-Intensity Exercise May Benefit Your Heart

Researchers in New Zealand recruited 16 middle-aged adults with type 2 diabetes. They randomly assigned two-thirds of them to exercise on a stationary bike for 20 minutes three times a week. Every one to three minutes, they pedaled hard enough to push their heart rate nearly to the max for their age, followed by a more moderate pace. The remaining participants maintained their regular fitness routines. Tests administered at the start and end of the three-month study showed that the high-intensity interval cycling led to improved heart function, reversing some of the early negative effects that type 2 diabetes has on heart health and potentially lowering the risk of heart disease. The finding is encouraging, though the small study size may have affected the results. Before you try a similar workout, ask your doctor if high-intensity exercise is safe for you.
