We compared the effects of submaximal and supramaximal cycling interval training on determinants of exercise performance in moderately endurance-trained men. Maximal oxygen consumption (VO2max), peak power output (P-peak), and peak and mean anaerobic power were measured before and after 6weeks (3 sessions/week) of submaximal (85% maximal aerobic power [MP], HIIT85, n=8) or supramaximal (115% MP, HIIT115, n=9) interval training to exhaustion in moderately endurance-trained men. High-intensity training volume was 47% lower in HIIT115 vs HIIT85 (304 +/- 77 vs 571 +/- 200min; P<0.01). Exercise training was generally associated with increased VO2max (HIIT85: +3.3 +/- 3.1mL/kg/min; HIIT115: +3.3 +/- 3.6ml/kg/min; Time effect P=0.002; Group effect: P=0.95), P-peak (HIIT85: +18 +/- 9W; HIIT115: +16 +/- 27W; Time effect P=0.045; Group effect: P=0.49), and mean anaerobic power (HIIT85: +0.42 +/- 0.69W/kg; HIIT115: +0.55 +/- 0.65W/kg; Time effect P=0.01; Group effect: P=0.18). Six weeks of submaximal and supramaximal interval training performed to exhaustion seems to equally improve VO2max and anaerobic power in endurance-trained men, despite half the accumulated time spent at the target intensity.
