운동이 비만 여성의 심근산소소비량과 심전도 QTc 간격에 미치는 영향 = The Effects of Exercise Training on Body Composition, MVO_2 and QTc Interval in Obese Woman

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effects of exercise staining on MVO_2 and electrocardiogram QTc interval in obese woman and to propose the desirable method for weight loss.
Subjects were fifteen obese women for this study. 8 subjects were prolonged QTc interval group and 7 subjects were normal QTc interval. They participated in exercise program consisted of aerobic exercise and weight training exercise at A Medical Center. The body composition including Boyd Weight, BMI, WHR and % Body Fat was measured. The resting and exercise(Bruce protocol 7th min) rate-pressure product(RPP) could be measured with HR and systolic BP for MVO_2 measurement. The electrocardiogram QTc interval was calculated with Bazzett's formula using automated software program. The measured data of this study were as follows:
1) After participating the exercise program consisted of aerobic exercise and weight training exercise, Body Weight, BMI, WHR and % Body Fat were significantly changed in two groups. (p<.05).
2. After participating in the exercise program consisted of aerobic exercise and weight training exercise, the resting and exercise MVO_2 using RPP were significantly changed in two groups(p<.05).
3) After participating in the exercise program consisted of aerobic exercise and weight training exercise, the electrocardiogram QTc interval were decreased but were not significantly changed in prolonged QTc interval group. (p<.29). However, it was significantly decreased in prolonged QTc interval(p<.00).
