Presentation Abstract

The purpose of this study was to examine the effects of intermittent blood flow restriction (BFR) compared to low- (LIIE) and high-intensity interval exercise (HIIE) on energy expenditure (EE) and substrate utilization. Participants randomly performed each interval exercise protocol, and then rested for a three-hour period, in which EE and substrate utilization were measured. Total EE was different between BFR (321.6 ± 30.1 kcals), HIIE (254.5 ± 33.5 kcals), and LIIE (287.1 ± 25.5 kcals). Fat oxidation (FatOx) in BFR (1hr = 0.14 ± 0.01 g / min, 3hr = 0.11 ± 0.01 g / min) was greater than LIIE (1hr = 0.08 ± 0.02 g / min, 3hr = 0.9 ± 0.02 g / min). This study suggests that the addition of intermittent BFR to LIIE may result in greater EE but similar substrate utilization compared to HIIE, albeit at a lower work rate.
