Presentation Abstract
Examine oxygen consumption (VO2), energy expenditure and respiratory exchange ratio (RER) during recovery following moderate-intensity exercise (MIE) and variable high intensity exercise (VIE) in healthy adults. METHODS: Two experimental conditions (MIE/VIE) were randomized/performed on separate days fasted. Total duration and total work were matched. NetVO2 was calculated as the VO2 above resting VO2. Energy expenditure (EE) and fat oxidation rate (FatOx) were calculated. VO2 and RER responses were compared. RESULTS: During recovery, net VO2 decreased in both conditions. No differences in net VO2 between conditions during recovery. During VIE/MIE, RER was 1.02 ± 0.4 and 0.96 ± 0.06, (P=0.06). During recovery, RER was lower in VIE compared to MIE at 30 and 45 minutes. FatOx near end of recovery was significantly greater in VIE than MIE. CONCLUSION: NetVO2 and EE were similar during recovery, VIE appears to alter fuel utilization patterns during recovery to lower RER and greater fat oxidation.
