Item Analysis of exercise intensity and energy expenditure of women participating in the Curves exercise program.(2006-07-30T19:49:16Z) Farris, Gregory D.; Kreider, Richard B., 1962-; Health, Human Performance and Recreation.; Baylor University. Dept. of Health, Human Performance and Recreation.The Curves program is designed to improve fitness. The purpose of this study was to identify exercise intensity, HR and energy expenditure in a group of women participating in the Curves program. Seventy-eight women (53.6 ± 7.09 yrs, 192.1 ± 30.43 pounds, 43.5 ± 4.52 % fat) performed the Curves workout on two occasions. Results show that mean HR was 119 ± 15 b/min which was equivalent to 79% max HR or 63 % HRR. Thirty-three women (52.7 ± 6.68 yrs, 193.1 ± 31.73 pounds, 1.8 ± 0.28 L/min VO2 max) performed the Curves 30-min workout on two occasions. Results show that the mean RER to perform the 30-min workout was 1.00 ± 0.07 and 0.98 ± 0.05 for the two sessions. Estimated caloric expenditure was 164.5 ± 25.19 kcals and 160.6 ± 28.36 kcals for the two sessions. Results indicate that the Curves program qualifies as moderate intensity exercise.Item Effects of a high protein diet on weight loss, markers of health, and functional capacity in senior-aged females participating in the Curves® fitness program.(2008-12-01T16:42:21Z) Galbreath, Melyn.; Kreider, Richard B., 1962-; Health, Human Performance and Recreation.; Baylor University. Dept. of Health, Human Performance and Recreation.Purpose: To determine the effectiveness of elderly females aged 60-75 years following the Curves fitness and weight loss program on body composition, markers of health, and functional capacity. Methods: 55 senior aged overweight females (66 ± 5 years; 79 ± 11 kg) were randomly assigned to one of three groups: High Protein diet + Exercise (HP); High Carbohydrate diet + Exercise (NCHO); or Exercise only (E). Participants were instructed to follow their respective nutrition plans and complete a supervised 30 minute Curves circuit resistance-training program three times a week. The participants underwent an array of tests at 0, 10 and 14 weeks. An analysis of variance (ANOVA) for repeated measures was used to analyze the data. Results: Subjects in the HP experiencing significantly greater weight loss (HP -4.8 ± 3.2%, NCHO -3.0 ± 2.9%, E -1.1 ± 2.3%, p=0.001), fat mass (HP -10.2 ± 5.9%, NCHO -5.7 ± 4.0% and E -2.7 ± 3.9%, p=0.001), and percent body fat (HP -6.3 ± 3.5%, NCHO -3.8 ± 3.4%, and E only -2.2 ± 3.6%). Improvements were also noted in an appetite regulating hormones leptin (HP -42.1 ± 21.3%, NCHO 43.4 ± 56.1% and E .80 ± 35.1%, p=0.000). No significant changes were observed in fat free mass or resting energy expenditure. All groups experienced improvements in strength, muscular endurance, aerobic capacity, and a number of markers of health. Summary: The Curves exercise and weight loss program is effective in senior aged females in promoting weight loss and favorable body composition changes. The greatest effects were seen in the HP group.Item Effects of glucosamine and chondroitan supplementation in women with knee osteoarthritis participating in the Curves fitness and weight loss program: a randomized, placebo controlled, double blind clinical trial.(2007-03-08T03:43:20Z) Magráns-Courtney, Teresa.; Kreider, Richard B., 1962-; Health, Human Performance and Recreation.; Baylor University. Dept. of Health, Human Performance and Recreation.The purpose of this study was to determine whether participation in the Curves fitness and weight loss program and/or ingesting a commercially available glucosamine and chondroitan joint support dietary supplement improved functional status and/or health outcomes in women with knee osteoarthritis (OA). Thirty sedentary women with OA participated in a 14-week exercise and diet program and ingested either a glucosamine and chondroitan supplement or placebo. Participants were assigned to follow an isoenergenic high protein/carbohydrate restricted diet (HPD) or high carbohydrate/low protein diet (HCHO). Subjects participated in a supervised 30-minute resistance training circuit program that was interspersed with calisthenic exercises and performed 3-d per week. At 0, 2, 10, and 14 weeks, subjects completed a battery of assessments. Data were analyzed by repeated measures analysis and are presented as means ± SD from baseline. Results indicated that women with knee OA experienced significant training adaptations including decreased body mass (3±4%), decreased fat mass (6%±8), decreased body fat (4%±3), increased 1 repetition maximal muscular strength (11%±12), increased muscular endurance (13%±12), increased isokinetic strength (ranging from 10-25%±4), decreased knee pain (112%±317), stiffness (70%±234), limitations in physical function (96%±1,356), improved quality of life variables of physical functioning (37%±52), energy/fatigue (55%±69), social functioning (40%±76), and mental health (22%±84). Perceptions of appetite (13%±36), hunger (17%±34), energy (24%±35), and quality of diet (19%±38) were also improved. Glucosamine chondroitan supplementation tended to decrease perceptions of pain, with no statistically significant improvement in strength, or functional status. However, a strong effect size (d=1.1) was observed in VAS knee pain and moderate effect sizes were observed in WOMACTM pain (d=0.4), left knee flexion (d=0.53), 1 repetition max (d=0.53), total work (d=0.72), and maximal systolic blood pressure (d=0.69). These findings suggest that glucosamine and chondroitan supplementation during a weight loss and fitness program may have therapeutic benefits for women with OA.
