High-intensity Training (HIT) May Prevent Heart Disease
The study included 57 adolescent schoolchildren (47 boys and 10 girls) who were randomly assigned to high-intensity training (HIT) or moderate-intensity exercise groups.
Both groups did three exercise sessions a week for seven weeks. The high-intensity training (HIT) group’s program consisted of a series of 20-meter sprints over 30 seconds, while the children in the moderate-intensity training (HIT) group ran steadily for 20 minutes.
By the end of the seven weeks, teens in the moderate-intensity group had completed a total of 420 minutes of exercise, compared to 63 minutes for those in the high-intensity training (HIT) group.
