摘要：This study compared the effects of an exercise only (EO) program with an exercise and nutrition (EN) program on body composition, body contour, and blood measures in overweight adults. The exercise program included 20 min each of resistance and aerobic training. The nutrition program required 1,200 to 1,800 kcal and 2 daily protein-rich meal replacement shakes or bars. Group 1 (n=38) did EO wks 1-12 and EN wks 13-24. Group 2 (n=37) did EN wks 1-24. During wks 1-12 Group 2 EN attained greater reductions in body weight, BMI, percent fat, fat weight, waist circumference, and hip circumference than Group 1 EO. During wks 13-24, Group 1 (EN condition) attained greater reductions in body weight, BMI, percent fat, fat weight, waist circumference, and hip circumference than during wks 1-12 (EO condition). During wks 13- 24, Group 2 EN experienced similar improvements as during wks 1- 12 in most assessments. After 24 wks, both groups improved in body weight, BMI, percent fat, fat weight, lean weight, waist circumference, hip circumference waist/hip ratio, systolic blood pressure, diastolic blood pressure, and HbA1c, but Group 2 attained greater reductions in percent fat and fat weight. The findings indicate that EN was more effective than EO for improving body weight, body composition, and body contours, with concurrent fat weight loss and lean weight gain.
