16주간의 복합운동과 체중 감량이 30~40대 비만 여성의 신체구성, 건강체력 및 생활습관병 지표에 미치는 영향 = Effects of a 16-Week Combined Exercise and Weight Reduction on Body Composition, Physical Fitness, and Lifestyle Disease in 30-40s Obese Women

다국어 초록 (Multilingual Abstract)

(Purpose) This study investigated the effects of a 16-week combined exercise and weight reduction program on body composition, physical fitness, and lifestyle disease indices. (Methods) Forty obese women aged 30-40 years were randomly assigned to one of four groups: exercise training+weight reduction (TR+WR), exercise training+weight maintenance (TR+WM), non-exercise training+weight reduction (NTR+WR), or non-exercise training+weight maintenance (NTR+ WM). (Results) Main results were as follows: 1) In the TR+WR group, significant improvements were observed in body composition (body weight, BMI, percent body fat, fat mass, and waist circumference), physical fitness (sit-ups, relative grip strength, sit-and-reach, VO2max) , and lifestyle disease indices (PP, FPG, FPI, HOMA-IR, TC, and LDL-C). 2) In the TR+WM group, significant improvements were found in body composition (percent body fat, fat mass, fat-free mass, waist circumference), physical fitness (sit-ups, sit-and-reach, VO2max), and lifestyle disease indices (FPG, HOMA-IR, TC, LDL-C, TC/HDL-C, LDL-C/HDL-C). The effect sizes of the interaction between group and time on these variables were 0.150-0.758, indicating large effects. (Conclusion) Single and combined treatments with exercise training and weight reduction had positive effects on body composition, physical fitness, and lifestyle diseases.
