High sensitivity C-reactive protein(hs-CRP), a marker of inflammation, was a risk factor for cardiovascular disease and metabolic syndrome. Hypertension and exercise are associated with hs-CRP. We had therefore assessed the effects of a health life gymnastics for 24weeks on blood pressure, hs-CRP concentration and metabolic syndrome risk factors in older women with hypertension. The subjects included 20 hypertension women(age, 73.2±2.4 yrs). We examined the effect of health life gymnastics on hs-CRP and metabolic syndrome risk factors. Measures of body composition, blood pressure, aerobic capacity, lipid profiles were all obtained before and after the interventions. Results of this study were as following: There were significant decrease in %fat, hs-CRP, SBP, WC, glucose and TG. There were significant increase in oxygen uptake capacity, LBM and HDL-C in exercise group. Also, there were the positive correlation of SBP, WC, glucose, TG and negative correlation of HDL-C with hs-CRP, respectively. This study demonstrates that health life gymnastics significantly results in modest improvements of hs-CRP, metabolic syndrome risk factors in older women with hypertension.

As a result of performing an experiment three times a week during 12 weeks with random assignment dividing the elderly women subjects into the taekwondo exercise group and control group, the body composition and health-related physical fitness were improved by the significantly decrease of weight and BMI and the increase of LBM in taekwondo group. Also, all the dangerous factors of dementia were significantly reduced thanks to the significantly improvement of LDL-cholesterol and HDL-cholesterol, which have positive effects on β -amyloid and homocysteine as dementia-causing factors. Therefore, for the elderly women, regular teakwondo exercise influences positively on body composition, health-related physical fitness and dementia-induced factors so it is expected to prevent dementia whose risk is high in elderly women in advance and eventually to help not only save the medical expenses but also improve their and their family's life satisfaction.
