abstract
The purpose of this study was to determine if different diet and exercise programs differentially affect android and/or gynoid body composition changes in sedentary women. 54 sedentary women (348 yrs, 356 kg/m2) were randomized to participate in the Curves (C) or Weight Watchers (W) weight loss programs for 16wks. Participants in the C program followed a 1,200 kcal/d diet for 1wk and 1,500 kcal/d diet for 3 wks (30:45 CHO:PRO). Subjects then ingested 2,000 kcals/d for 2wks (45:30 CHO:PRO) and repeated this diet while participating in the Curves with Zumba program 3dwk. Remaining subjects followed the W pointbased diet program, received weekly counseling, and were encouraged to exercise. DEXA body composition with android (A) and gynoid (G) measurements were analyzed at 0 and 16 wks. MANOVA revealed a significant time (p<0.001) and group x time (p=0.004) effect. Both groups had similar changes in AFM (W 419760, C 624700 g, p=0.31), ABF (W 2.110, C 4.96 %, p=0.24), and GFFM (W 6391,853, C 91,247 g p=0.16). Differences were seen in AFFM (W 313614, C 49403 g, p=0.02), GFM (W 3951,657, C 1,3981,728 g, p=0.03), GBF (W 0.68, C 4.26 %, p=0.06), and the lean index to height (W 2.44.6, C 0.51.5 kg/m2, p=0.005). Results indicate that different types of diets can differentially affect changes in A and G body compositionGrant Funding Source: Supported by Curves International (Waco, TX)
