Two groups of stable patients with coronary artery disease (CAD) regularly walked on treadmills three times a week for ten weeks. One group walked at high intensity (80-90% of VO2peak); the other groups walked at moderate intensity (50-60% of VO2peak)
The results from this study, High intensity aerobic interval exercise is superior to moderate intensity exercise for increasing aerobic capacity in patients with coronary artery disease were:
After training VO2peak increased by 17.9% (P=0.012) in the high intensity group and 7.9% (P=0.038) in the moderate intensity group. The training-induced adaptation was significantly higher in the high intensity group (P=0.011).
Their conclusion:
High intensity aerobic interval exercise is superior to moderate exercise for increasing VO2peak in stable CAD-patients.
