Effects of Interval Training Effects on Cardiac Fibrosis

Cardiac patients have completed 36 times of exercise training with the exercise frequency of 2-3 times per week. Subjects performed five 3-minute intervals at 80% of VO2peak and each interval was separated by 3-minute exercise at 40% of VO2peak after the warm-up period. The exercise session was terminated by 3-minute cool-down at 30% of VO2peak.
