High aerobic intensity interval training at % of maximal heart rate is more effective than continuous training with low to moderate intensity in improving maximal oxygen uptake in healthy young men.

Pai definition

Maximal cardiac stroke volume was improved to a similar extent in high aerobic intensity interval training only. It is concluded that high aerobic intensity endurance training is significantly more effective than isocaloric training at lactate threshold (85% of maximal heart rate) or 70% of maximal heart rate, in improving maximal oxygen uptake and cardiac stroke volume.

Improvements in maximal oxygen uptake corresponded with changes in stroke volume, indicating a close link between the aerobic intensity interval training at % of peak heart rate significantly improves peak cardiac stroke volume and resting left ventricular ejection fraction in coronary artery disease patients.
