Extremely short duration high intensity interval training substantially improves insulin action
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.
