Short Bursts of Exercise Help Health

By Miriam E. Tucker , ,


Too busy to work out? Consider this: Even mere minutes of exercise can yield health benefits. In a recent study, sedentary men were randomly assigned to two different exercise routines three times a week. Nine men performed three 20-second full-intensity cycling sprints separated by two minutes of slower cycling, while 10 men cycled continuously for 45 minutes at a moderate intensity. Another six men did not exercise. The two exercise sessions also included a two-minute warm-up and three-minute cool down. Despite the difference in workout length, after 12 weeks, the two exercise groups showed similar improvements in heart and lung fitness as well as insulin sensitivity, an important factor in preventing type 2 diabetes down the road.
