Excess post-exercise oxygen consumption (EPOC) is defined as an increase in oxygen consumption (VO2 ) following the completion of exercise. Previous research has primarily focused on the influence of endurance-type exercise on EPOC. Therefore, the purpose of this study was to compare the effect of a light versus heavy resistance exercise protocol of equal work on EPOC. Ten male subjects performed two days of onerepetition maximum (1-RM) testing and two experimental trials (Light: 3 sets of 15 repetitions at 40% 1-RM; Heavy: 4 sets of 4 to 8 repetitions at 80 to 87.5% 1-RM). VO2, caloric expenditure, blood lactate concentration, heart rate, and blood pressure were measured at baseline, 5, 15, 30, 60, 90 and 120 minutes post-exercise, and 24 hours postexercise. For both exercise protocols, VO2 and caloric expenditure were significantly greater at 5 min post-exercise compared to baseline. In addition, at 5 min post-exercise, VO2 and caloric expenditure were greater during the light protocol compared to the heavy protocol. During the 120 minutes post exercise, there was no significant difference in EPOC (44.0 ± 43 and 39.1 ± 44.3 mL·kg- 1 ; P = 0.786) or total caloric expenditure (15.1 ± 13.8 and 12.9 ± 16.9 kcal; P = 0.742) between the light and heavy protocols. The data suggests that for resistance exercise protocols with an equal work volume, there is no difference in the magnitude and duration of EPOC.
