| Annotation | It has been shown that basal metabolic rate (BMR) decreases with age. The extent to which some of the decrease can be reversed by exercise in older men and women is unclear. Resistance exercise has been shown to significantly increase muscle mass in older people, and because muscle is a highly active metabolic tissue, there is potential to increase BMR as a secondary outcome to training adaptation. 12 healthy men aged 59-77 years performed single-leg knee extension exercise (right and left leg) and bench press lifts (16 sets, 10reps/set with timed recovery between sets) at 75% of the individual's three repetition maximum (3RM). Subjects only performed the concentric phase of the lift. BMR was measured twice: once after a non-exercise control period, and again 48 hours after a bout of resistance exercise. BMR was significantly increased 48 hours after exercise (EX) compared to control (CON). Calculated over a 24hr period, energy expenditure corresponded to 1570 ±193 and 1627 ±193 kcal/24hr for the CON and EX measures, respectively. The authors conclude that in healthy 59-77 year old men, an acute bout of resistance exercise causes a sustained increase in BMR that persists for up to 48 hours after exercise. (RH). |
