In a recent study 16 young men performed 2 weeks of supervised high intensity training (HIT) comprising of a total of 15 min of exercise (6 sessions; 4–6 × 30-s cycle sprints per session). The subject performed about 250 kcal of work each week compared with the 2000 to 3000 kcal a week consumed during a typical aerobic training program. The results were surprising.
The conclusion from this study, High-intensity resistance training improves glycemic control in older patients with type 2 diabetes.:
A May 3, 2007 New York Times article, A Healthy Mix of Rest and Motion, suggests that for at least one workout a week it pays to alternate short bursts of high-intensity exercise with easy-does-it recovery. This type of high intensity interval training comes in many forms.
From the article The Best Exercise for Diabetics:
Q: What is exercise intensity?
A: In simplest terms, it's how hard an exercise is at a point in time. The technical definition is the level of momentary exertion during exercise.
Q: Why is it important?
A: Exercise of sufficient intensity is necessary to stimulate the body to make a change. When the body is worked beyond what it is equipped to handle, the body adapts as a form of self-protection.
From this study, Strength Training Early After Myocardial Infarction, comes this quote:
“In selected patients, low-to-moderate intensity strength training performed early after infarction is effective and may have lower rates of cardiovascular problems than aerobic exercise.”
