abstract
42 sedentary women (337 yrs, 1647 cm; 9319 kg; 467% body fat, 356 kg/m2) were randomized to participate in the Curves (C) or Weight Watchers (W) 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) and repeated this diet while participating in the Curves with Zumba program 3dwk. Remaining subjects followed the W pointbased diet program. Data were obtained at 0, 4, 10, & 16 wks and analyzed by MANOVA. Both programs increased ratings of physical functioning (16.534%, p=0.002), vitality (19.930%, p=0.002), bodily pain (15.733%, p=0.03), and general health (16.740%, p=0.001) while tending to increase role physical (14.746%, p=0.11) and role emotion (6.54%, p=0.08). Significant interactions were seen in physical function (C 89.711, 91.89, 93.87, 94.110; W 75.287.6, 87.614, 88.614, 88.116, qp =0.05) and vitality (C 53.514, 61.813, 62.113, 60.012; W 48.112, 55.210, 54.015, 57.916, qp =0.05) with participants in the C group experiencing significantly higher values. Results indicate that participation in the C and W programs generally improved markers of quality of life and that subjects participating in the C group may experience greater improvement in vitality than those in the W group.
