ANTUNES, Hanna K.M. et al. Analysis of resting metabolic rate and body composition in elderly males before and after six months of endurance exercise. Rev Bras Med Esporte [online]. 2005, vol.11, n.1, pp.71-75. ISSN 1517-8692.

The aim of this study was to compare basal metabolic rate and body composition before and after an endurance-type physical fitness program. The study involved 46 sedentary aging males, aged 60-75 (66.97 ± 4.80 years), who were randomly allocated to two groups: 1) control group, which was asked not to change their daily routine or join a regular physical fitness program; and 2) experimental group, who took part in an aerobic fitness program consisting of working on cycle ergometer three times a week (60 minutes) on alternate days for six months, at heart rate corresponding to ventilatory threshold 1 (VT-1) intensity. Subjects were submitted to measurement of body composition (DEXA); indirect calorimetry, blood analysis and ergospirometric testing. After the study period, the authors found a significant decrease in thyroid hormones as well as basal metabolism changes in both groups, but no changes in body composition. The experimental group, however, showed a significant increase in peak oxygen uptake and workload at VT-1 intensity. The data suggest that although an aerobic exercise program at VT-1 intensity is not enough to alter the basal metabolism and body composition of healthy seniors, it does lead to cardiovascular benefits.
