Abstract
This study determined the influence of walking with blood flow restriction (BFR) on
the excess post-exercise oxygen consumption (EPOC) of healthy young men. 17 healthy
young men (22.1±2.9 years) performed graded treadmill exercise to assess VO2peak. In a randomized fashion, each participant performed 5 sets of 3-min treadmill exercise
at their optimal walking speed with 1-min interval either with or without BFR. Participants
were then seated in a chair and remained there for 30 min of recovery. Expired gases
were continuously monitored during exercise and recovery. BFR increased the O2 cost of walking as well as its relative intensity and cumulative O2 deficit (p<0.05). The EPOC magnitude after walking with BFR was greater than in the
non-BFR condition (p<0.05). No differences between conditions were seen for the duration
of EPOC. The EPOC magnitude was no longer different between conditions after controlling
for the differences in relative intensity and in the cumulative O2 deficit (p>0.05). These data indicate that walking with BFR increases the magnitude
of EPOC. Moreover, they also demonstrate that such increment in EPOC is likely explained
by the effects of BFR on walking relative intensity and cumulative O2 deficit.
