36주간 저항성 운동이 비만노인의 신체구성, 체력 및 혈중 지질에 미치는 영향

Abstract

Purpose: To examine the effects of a 36-week resistance training program on body composition, fitness and blood lipid profiles in the obese elderly. Method: fourteen subjects were assigned into the resistance training group. The 12-16 exercise sessions were performed for 60min with 15-25 repetitions twice per week for 36 weeks. Data were analyzed by paired t-test with SPSS version 12.0 for Windows. Results: Significant changes were evident in weight (t=5.983, p<0.001), body mass index (t=5.922, p<0.001), % body fat (t=3.480, p=0.004), and fat free mass (t=-2.592, p=0.022). Concerning exercises, no significance was noted for back scratch (t=-1.814, p=0.093), but were for 2-min step (t=-3.075, p=0.009), arm curl (t=-2.223, p=0.045), chair stand (t= -3.671, p=0.003), chair sit and reach (t=-2.508, p=0.026), and 8-ft up and go (t=5.545, p<0.001). No significant changes were evident in total cholesterol (t=1.189, p=0.279), and total glucose (t=0.689, p=0.517), while the change in high-density lipoprotein was significant (t=3.535, p=0.012). Conclusion: The 36-week resistance training program enhanced body composition and physical fitness, but not blood lipid profiles in obese elderly subjects.
