Interval Training Increases Heart Health
For a healthier heart, add interval training to your exercise routine, say researchers who studied a small group of people with type 2 diabetes and without. Each person did one-minute bouts of resistance (using weights) or cardio (biking) exercise, with one-minute rests in between, on two separate days. On another day, they sat still for 20 minutes. At one and two hours post exercise, researchers saw improvements in the function of heart cells involved in blood flow and vessel health. Benefits were seen for both types of exercise and in people with and without diabetes, although the effect was stronger in those with diabetes. And as you might have guessed, sitting still had no effect.
