Resumo55 sedentary women (66±5 yrs, 79±11 kg; 44±4% body fat) participated in the Curves circuit resistance-training program 3-d per wk for 14 wk. 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 kcals/d maintenance diet for 4 wks. The HC and maintenance diets contained 55% CHO, 15% PRO, and 30% Fat while the HP diet contained 7–15% CHO, 55–63% PRO, and 30% Fat. Data were analyzed by repeated measures ANOVA and are presented as means ± SD changes from baseline. After 14-weeks, subjects lost an average of 2.3±2.5 kg. Training significantly increased overall 1RM bench press (21.3±28%, p=0.001); 1RM leg press (33.1±37%, p=0.001); BP lifting volume (29.5±72%, p=0.006); LP lifting volume (23.2±57%, p=0.01); relative peak oxygen uptake (10.7±24%, p=0.001), and, 6-min walk test performance (7.6±9%, p=0.001). Resting HR (-3.1±16%, p=0.22) was not non-significantly decreased. SBP (-4.0±12 %, p=0.02) and DBP (-4.7±12 %, p=0.007) were significantly decreased after 10 wks of exercise and dieting. No significant interactions were observed among groups. Results indicate that the Curves fitness program improves muscular strength, muscular endurance, aerobic capacity, functional capacity, and general resting cardiovascular hemodynamics in senior-aged women.
