| dc.description.abstract | The effect of exercise mode and age on excess post-exercise oxygen consumption (EPOC) has not been previously considered. Therefore, this study determined EPOC following aerobic versus resistance exercise in 9 healthy younger men (age = 22.9 ± 2.3 yr; VO2max = 48.3 ± 5.9 ml/kg/min) and 10 healthy older men (age= 65.8 ± 3.3yr); VO2max = 37.9 ± 5.1 ml/kg/min) using a repeated measures ANOVA crossover design. Resistance exercise consisted of one set often repetitions at 50% 1-RM followed by five sets of eight repetitions at 75% of 1 RM for leg press and leg (knee) extension for 30 minutes. Aerobic exercise consisted of 5 minutes of cycling at 50% VO2max followed by 30 minutes cycling at 70% VO2max. Resting energy expenditure (EE) was measured via indirect calorimetry at baseline before each exercise condition and post-exercise for 6 hours. No difference was observed in resting EE, between groups or days, prior to exercise. At 6 hours following exercise, EPOC remained significantly (p ≤ 0.05) above resting values, following both types of exercise in both age groups. The results also showed that EPOC was significantly (p ≤ 0.05) greater in younger men compared to older men, regardless of exercise mode. Further, there was a trend for aerobic exercise to exhibit a greater post-exercise VO2 than resistance exercise in older men. These findings suggest that men embarking on an exercise program to increase their energy expenditure in order to lose or maintain body weight may want to consider aerobic or resistance exercise of moderate intensity for at least 30 minutes in order to significantly extend energy expenditure beyond the cessation of the exercise session itself. The results also suggest that for younger men there does not seem to be one exercise mode that is superior in terms of energy expenditure. However, older men may benefit more from aerobic exercise than resistance exercise to maximize post exercise energy expenditure. | en_US |
