Primary outcomePrimary: Maximal Oxygen Consumption (ml.Kg-1.Min-1) — 31.5; 31.4; 35.4; 32.4 ml/kg/min — p=<0.01
Summary
High intensity interval training (HIIT) and circuit training (CT) are popular methods of exercise, eliciting improvements in cardiorespiratory fitness (CRF). However direct comparisons of these two training methods are limited.
