12주간 수영운동이 중년여성의 호흡순화능력, 혈청지질수준 및 체지방률에 미치는 영향

Abstract

The purpose of this study is to investigate changes of physical fitness by cardiopulmonary function, blood lipids and percent of body fat according to 12 weeks swimming exercise in middle-aged women. It could be a basis for efficient exercise prescription for middle-aged women. The subjects of this study were totally 24 women and divided into two groups : swimming group (n=12) and compared group (n=12). The swimming exercise was performed 5days per a week during 12 weeks by intensity of 60-80% HRmax. The results are as follow: 1. On the difference of cardiopulmonary functions, maximum oxygen uptake (502.6㎖/min, p.Ol) and Maximum oxygen uptake per body weight (9.8㎖/kg/min, p.Ol) were significantly increase. HRmax (8.7beats/min, p.05) and HRrest (2.2beats/min, p.05) were significantly decrease. SBP (9.4mmHg, p.05) were significantly decrease, but DBP was not a significant difference. 2. TG(19.9mg/㎗, p.05) and FFA(21.7mg/㎗, p0.5) were significant decrease. HDL-C(5.9mg/㎗, p0.001) were significant increase. and TC and LDL-C was not a significant difference. 3. Percent of Body Fat were significantly increase(3.7%, p.05). The weight were decreased but it shows not static significant meaning. Because increase of Percent of Body Fat could be a risk factor of coronary arteriosclerosis or diabetes, it must be improve. With aging, strength and cardiopulmonary functions are decrease. So it is important to take aerobic exercise regularly with use of gross muscle group.
