Abstract

The purpose of this study was to investigate the effect of different frequencies of resistance training on an individual's resting metabolic rate (RMR). Six healthy males between the ages of 18 and 35 participated in two separate trials. The first trial involved two full-body resistance training bouts, 48 hours apart with RMR measurements pre- and post-bout and a RMR measurement 24 hours following each. The second trial consisted of four split-body resistance training bouts on four consecutive mornings with RMR measurements pre- and post-bout each morning with a fifth morning for one final RMR measurement, 24 hours after the final bout of exercise. This was a repeated measures design and the order of conditions was randomized. Analysis of variance was used to interpret the data. It was concluded that mean RMR for each protocol was not significantly different (1.5275 ± 0.1976 kcal·min-1, 1.5273 ± 0.1690 kcal·min-1 ). A secondary finding was that respiratory exchange ratio (RER) decreased as RMR increased, showing a greater oxidation of fat post exercise, although there was not a statistically significant difference. These results led to the conclusion that RMR will be the same for two different resistance training programs as long as the work is constant between both. The practical application of these results would be that if an individual is choosing a resistance training regimen to raise RMR and lose weight, the program can be selected based on time constraints.
