단기간 동안의 사이클 및 트레드밀 훈련이 비만 여성의 신체구성, 혈압 및 기초체력에 미치는 효과

Abstract

The purpose of this study was to investigate the short-term effect (4 weeks) of cycle and treadmill training on body composition, blood pressure and physical fitness in obese women. Subjects of this study were 24 obese women and divided by randomized crossover design into 3 groups: control group (CG, n=8), cycle ergometer exercise group (CEG, n=8), treadmill exercise group (TEG, n=8). Body weight (BW), fat free mass (FFM), body fat mass (BFM), % body fat (%BF), body mass index (BMI) were measured for body composition. Systolic blood pressure (SBP), diastolic blood pressure (DBP) were measured for blood pressure. Grip strength, back strength, sit-up, sit and reach, physical efficiency index (PEI) were measured for physical fitness level. Two-way repeated measures ANOVA was used to analyze the difference according to the group and the exercise period. As the result of this study, BFM and BMI were significantly decreased in CEG, BFM and %BF were significantly decreased in TEG. Sit and reach, back strength and PEI was significantly higher than before training in CEG and TEG, sit-up was significantly higher than before training in CEG. There was no significant different between treadmill and cycle ergometer exercise in all measurement. Our finding suggested evidence that both cycle and treadmill exercise for short-duration are effective to decrease body fat and to increase back strength and cardiorespiratory endurance.
