Purpose: The purpose of this investigation is to assess exercise post oxygen consumption (EPOC) in response to high-intensity interval training versus moderate continuous training cycling. Methods: Two recreationally active men (21.3 ± 3.51 yrs; 182.83 ± 6.25 cm; 79.36 ± 8.69 kg; 3.57 ± 0.10 L∙min-1) completed three trials: a graded exercise test, and two cycling trials in a randomized order: a high-intensity interval (HII) and moderate continuous (MC) bout. Baseline VO2 was assessed for 30 minutes prior to each cycling trial. During HII, participants completed 15 90-second bouts of exercise at 85% VO2max with 90-second active recovery periods at 25% VO2max. During MC participants cycled for 45-minutes at 65% VO2max. For both conditions, participants completed a 5-minute warm-up and 3-minute cool down at 25% VO2max. Recovery VO2 was assessed within 3 minutes of completing the cool down for 60 minutes. Respiratory gasses were analyzed every 5 minutes during recovery. Results: Preliminary data shows an average oxygen consumption of 3.87 ± 0.83 mL/kg/min for HII and 3.91 ± 0.52 mL/kg/min for MCT. Also, the average oxygen consumption at the beginning of rest was 5.32 ± 0.48 ml/kg/min and declined to 3.93 ± 0.31 mL/kg/min at the end of recovery. Conclusion: Average and decline in VO2 response was similar during 60 minutes of quiet rest in the HII compared to the MC despite differences in exercise intensity during each protocol.

Purpose: To assess exercise post oxygen consumption (EPOC) after high-intensity interval (HII) versus moderate-continuous cycling (MC). Methods: Recreationally active men (n=2) completed two cycling trials: HII, (fifteen 90-second bouts at 85%VO2Max); and MC at 65% VO2Max, each lasting 53 minutes. Respiratory gasses were analyzed every 5 minutes during a 60-minute recovery. Results: Average EPOC was 3.87±0.83 mL/kg.min for HII and 3.91±0.52 mL/kg.min for MCT. EPOC declined from 5.32±0.48 mL/kg.min to 3.93±0.31 mL/kg.min at the end of recovery. Conclusion: Despite differing intensity in exercises, the average consumed and decline in VO2 response was similar in both trials.
