We compared the effects of submaximal and supramaximal cycling interval training on determinants of exercise performance in moderately endurance‐trained men. Maximal oxygen consumption ( VO 2max ), peak power output (P peak ), and peak and mean anaerobic power were measured before and after 6 weeks (3 sessions/week) of submaximal (85% maximal aerobic power [ MP ], HIIT 85 , n = 8) or supramaximal (115% MP , HIIT 115 , n = 9) interval training to exhaustion in moderately endurance‐trained men. High‐intensity training volume was 47% lower in HIIT 115 vs HIIT 85 (304 ± 77 vs 571 ± 200 min; P < 0.01). Exercise training was generally associated with increased VO 2max ( HIIT 85 : +3.3 ± 3.1 mL/kg/min; HIIT 115 : +3.3 ± 3.6 ml/kg/min; Time effect P = 0.002; Group effect: P = 0.95), P peak ( HIIT 85 : +18 ± 9 W; HIIT 115 : +16 ± 27 W; Time effect P = 0.045; Group effect: P = 0.49), and mean anaerobic power ( HIIT 85 : +0.42 ± 0.69 W/kg; HIIT 115 : +0.55 ± 0.65 W/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 VO 2max and anaerobic power in endurance‐trained men, despite half the accumulated time spent at the target intensity.
