Resumo55 senior-aged women (66±5 yrs, 79±11 kg; 44±4% body fat) participated in a 3-d/wk resistance-training program for 14 wks. Subjects were assigned to an exercise only group (E) or a high carbohydrate (HC) or high protein (HP) diet group. Diets consisted of 1,200 kcal/d for 1-wk, 1,600 kcal/d for 9 wks, followed by a 2,100 kcal/d maintenance phase for 4-wks. The HC group diet contained 55% CHO, 15% PRO, and 30% Fat while the HP diet contained 7–15% CHO, 55–63% PRO, and 30% Fat. The maintenance diet was 55% CHO, 15% PRO, and 30% Fat. Data were analyzed by repeated measures ANOVA and are presented as means ± SD changes from baseline for the E, HC, and HP groups, respectively. After 10 weeks, women who followed the HP diet experienced a significantly greater (p<0.003) loss in total scanned mass (−0.3±1.6; −1.3±1.8; −2.9±2.5 kg), fat mass (−0.8±1.3; −1.5±1.3; −2.8±1.9 kg), and body fat (−1.0±1.6; −1.2±1.4; −2.1±1.6 %). Intermittent dieting maintained losses in scanned body mass (−0.5±1.6; −1.3±2.1; −3.1±2.7 kg), fat mass (−0.8±1.1; −1.9±1.4; −3.3±2.0 kg), and body fat (−0.9±1.5; −1.8±1.5; −2.7±1.5 kg). No differences were seen in fat free mass (10-wks 0.5±1.4; 0.12±1.4; −0.11±1.3 kg; 14-wks 0.36±1.5; 0.58±1.6; 0.22±1.5 kg, p=0.41). Results indicate that senior-aged women experience greater fat loss while following a HP diet during resistance-training.
