As can be seen in Table 1, there was a significant reduction in body mass (-1.72 [+ or -] 0.41 kg; P < 0.001), fat mass (-2.23 [+ or -] 0.38 kg; P < 0.001), and percentage body fat (-1.90 [+ or -] 0.22%; P < 0.001) following the exercise intervention, while fat-free mass was preserved at baseline levels (+0.52 [+ or -] 0.17 kg; P = 0.081).

These tests included maximum oxygen consumption, chest press, isometric and double-knee extension, thigh muscle mass by single-slice CT, and fat-free mass by DXA to evaluate muscle function, ratio of visceral to total fat to characterize fat distribution, and fasting glucose and insulin for carbohydrate metabolism.
Basal metabolic rate is primarily dependent on the fat-free mass, however there is no knowledge on the correlation between basal metabolic rate and fat-free mass.
Furthermore, we compared classical GFR measurement methods with those based on bioimpedance analysis-derived body cell mass (BCM) and fat-free mass BSA.
