Excess post-exercise oxygen consumption (EPOC) can be effective in the maintenance or reduction in body weight when utilized fittingly. EPOC is affected, in part, by exercise intensity, though it is unclear how post-exercise VO2 is affected through supramaximal running. Only one other researcher (LaForgia et al. 1997) had compared high-intensity submaximal running and supramaximal running, however, the two trials were not relative in exercise duration (30-min vs 60-min; respectively). PURPOSE: Therefore, the purpose of this study was to compare the EPOC response after a high intensity submaximal continuous run (CEE) (85% VO2max) and a supramaximal interval run (SIE) (105% VO2max) when both trials were equated in energy expenditure and exercise duration. METHODS: Six male recreational runners (age = 24.5 + 1.9 yr.; weight = 72.7 + 13.7 kg; VO2max = 55.3 + 5.7 ml/kg/min; height = 177.7 + 6.3 cm; body fat = 8.2 + 1.7%) completed two iso-caloric treadmill running sessions (continuous running: 19-min at 85% VO2max; interval running: 8 x 1-min intervals at 105% VO2max with 2-min active rest at 55% VO2max) in a randomized counterbalanced design. Post-exercise oxygen consumption was measured for 30-min: immediately post-exercise and 3-h post-exercise. RESULTS: The magnitude of VO2 immediately post-exercise was 9.11 + 0.69 liters O2 (CEE), and 9.38 + 1.5 liters O2 (SIE), with no interaction between treatments and time; however, there was a main effect between time points (p < .05). CONCLUSIONS: These findings suggest that running at 85% VO2max elicits a similar post-exercise VO2 response as 105% VO2max interval running when bouts are equated for caloric expenditure and exercise duration.
