467 sedentary women (45±11 yrs, 163±7 cm; 93±17 kg; 45±5% body fat) were assigned to an exercise & no diet group (E); an exercise & high calorie diet (HCD) group (2,600 kcals/d), or a low calorie high carbohydrate (HCHO), high protein (HP), or very high protein (VHP) diet. Diets consisted of 1,200 kcal/d for 1‐wk and 1,600 kcal/d for 9 wks and contained 30% fat, 40–55% CHO on the HCD and HCHO diets and 50–63% P on the HP and VHP diets. During the maintenance phase, subjects ingested 2,600 kcal/d (55% C, 15% P, 30% F) and dieted for 2‐d (1,200 kcal/d) only if they gained 3 lbs. Subjects participated in a supervised Curves fitness program 3‐d per wk. Data were obtained at 0, 10, and 14 wks and were analyzed by repeated measures ANOVA. Data are presented as means ± SD changes from baseline. After 14‐weeks, subjects lost an average of 3.7±4.2 kg. Training significantly increased overall 1RM bench press (5.1±8%, p=0.001); 1RM leg press (13.2±20%, p=0.001); BP lifting volume (21.4±104%, p=0.001); LP lifting volume (36.4±306%, p=0.047); and relative peak oxygen uptake (8.1±21%, p=0.001). Resting HR (−2.6±14 %, p=0.03 at 10‐wks), SBP (−3.0±11 %, p=0.001), and DBP (−3.5±12 %, p=0.001) were significantly decreased at 10 and/or 14 weeks. No significant interactions were observed among diet groups. Results indicate that the Curves fitness program improves muscular strength, muscular endurance, aerobic capacity, and general resting cardiovascular hemodynamics.
