title: Effects of submaximal and supramaximal interval training on determinants of endurance performance in endurance athletes.
abstract: 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 (Ppeak), and peak and mean anaerobic power were measured before and after 6 weeks (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 HIIT115vs HIIT85(304 ± 77 vs 571 ± 200 min; P < 0.01). Exercise training was generally associated with increased VO2max(HIIT85: +3.3 ± 3.1 mL/kg/min; HIIT115: +3.3 ± 3.6 ml/kg/min; Time effect P = 0.002; Group effect: P = 0.95), Ppeak(HIIT85: +18 ± 9 W; HIIT115: +16 ± 27 W; Time effect P = 0.045; Group effect: P = 0.49), and mean anaerobic power (HIIT85: +0.42 ± 0.69 W/kg; HIIT115: +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 VO2maxand anaerobic power in endurance-trained men, despite half the accumulated time spent at the target intensity.
