複合運動이 高血壓 患者의 心血管疾患 危險因子에 미치는 影響

Abstract

The purpose of this research was to examine the effect of combined exercise on cardiovascular disease risk factors in elderly women with hypertension. 40 subjects were divided into combined aerobic and resistance exercise training (n=20) and control (n=20) groups. The combined exercise was composed of aerobic and resistance exercise program. Aerobic exercise program was carried out under the condition of 50～69% of HRmax for 30～40 minutes, 5 days a week for 16 weeks and resistance exercise program was given to utilizing elastic band exercise using the Thera band with the intensity of 10 repetitions and 3 sets for 30～40 minutes, three days a week for 16 weeks. Cardiovascular disease risk factors(body composition, blood pressure, blood lipids, insulin resistance, C-reactive protein) of all subjects were measured at before and after the program participation. All data were expressed as mean and standard deviation and also paired and independent t-test was performed to test the significant levels of differences within and between groups by using SPSS program. Significance was set at the α=.05. Body weight was significantly decreased within exercise group. percentage body fat and waist circumference were significantly decreased within exercise group, and exercise group was shown that there were significant differences of % body fat and waist circumference, compared with control group. Lean body mass was significantly increased within exercise group, and exercise group was shown that there was a significant difference of lean body mass, compared with control group. Systolic and diastolic blood pressure were significantly decreased within exercise group, and exercise group was shown that there were significant differences of systolic and diastolic blood pressure, compared with control group. TG, TC, and LDL-C were significantly decreased within exercise group, and exercise group was shown that there were significant differences of TG, TC, and LDL-C, compared with control group. HDL-C was significantly increased within exercise group, and exercise group was shown that there was a significant difference of HDL-C, compared with control group. However, insulin resistance was not shown that there was any significant difference within and between group. On the other hand, C-reactive protein was significantly decreased only within exercise group after application of exercise program. In summary, when considering the above results, combined treatment of aerobic and resistance exercise could improve the levels of body composition, blood pressure, and blood lipids. Furthermore combined exercise could decrease the concentration of C-reactive protein.
