복합운동이 중년 비만여성들의 혈청 지질대사와 Adipocytokine에 미치는 영향

Abstract

The purpose of the present investigation was to evaluate the effects of 12 weeks exercise program participation on changes in %fat, serum lipid metabolism, leptin and adiponectin concentrations by groups in middle aged women. 20 obese women(above %fat 30) were participated in 12 weeks combined exercise program by exercise types and their %fat, leptin and adiponectin levels were assessed before program(0 week) and after program(12 weeks). Experimental groups were divided into two groups, control group(CG, n=10) and combined exercise group(EG, n=10), respectively. Regularly combined exercise(walking & resistance exercise) performed for 12 weeks. All data were expressed as mean and standard deviation by using SPSS/PC+ program, and to evaluate the differences before and after program groups, data were analyzed by paired t-test(a≤.05) and 2-way ANOVA was performed to examine the differences between groups and within groups by variables. In TC, TG and LDL-C after 12 weeks exercise program was decreased significantly in combined exercise group(p0.05), and in HDL-C after 12 weeks exercise program was increased significantly in combined exercise group(p0.05). In leptin response after 12 weeks exercise was decreased significantly in combined exercise group(p0.05). In adiponectin response after 6 weeks exercise was increased significantly in combined exercise group(p0.05). The change of leptin concentration was statistical significant difference between groups and within groups, and there was significant difference between group × period interaction(p0.01). And the change of adiponectin concentration was statistical significant difference within groups(p0.05). In conclusion, the regular combined(walking & resistance) exercise altered serum lipid metabolism, leptin and adiponectin responses in middle-aged obese women. Leptin and adiponectin responses to exercise training in obese women appear to be associated with body composition(body weight and %fat) alterations and exercise type(aerobic exercise or resistance training).
