Less Intense Workout Gets Good Results
A long yet mild exercise session may be enough to improve blood glucose control the next day, researchers report. In a study, 11 obese adults without diabetes performed a low-intensity workout—a combination of walking, jogging, and cycling—to burn 350 calories over a leisurely 70 minutes. The following morning, researchers measured the participants’ insulin sensitivity and found it was 35 percent better than it had been on a morning after a day without exercise. The benefits weren’t as marked when the participants exercised harder—expending 350 calories over 55 minutes instead of 70. The researchers say that the extra benefits may be due to the longer duration of exercise in the lower-intensity group, though more study is needed.
