Good luck with this:
Short bursts of exercise can benefit heart health just as much as tedious endurance training, a new study suggests.
The research, published in the American Journal of Physiology — Regulatory, Integrative and Comparative Physiology, is good news for time-strapped exercisers. It supports the notion that people who engage in brief, high-intensity forms of exercise reap the same cardiovascular health benefits as those who exercise at moderate intensity for a longer period of time.
Researchers at McMaster University in Canada recruited 20 healthy men and women whose average age was 23. All of the study subjects rode stationary bikes. Some exercised five days a week, doing 40 to 60 minutes of moderate-intensity cycling. Others did four to six sets of 30-second sprints on the cycle, allowing 4.5 minutes of recovery time between sets; their total exercise time was about 15 to 25 minutes just three days a week.
After six weeks, the researchers found that the intense sprint interval training improved the structure and function of arteries as much as traditional, longer endurance exercise.
I foresee a bunch of middle-aged weekend warriors keeling over after a hard 220. Starting with me. When I was younger and much more foolish I actualy enjoyed wind sprints and interval training as a diverting excursion to a different destination in the wide world of pain. No more.
