Abstract

The purpose of this experiment was to compare the energy expenditure and the physiological response among two groups by percent body fat(group A: 30-35% body fat, B: 35-40% body fat) to walking and running at several equivalent speeds. Subjects in group A and B followed A group(mean$\pm$SD, age; 24.0$\pm$0.4yrs, body fat; 32.3$\pm$0.7) and B group (age; 25.2$\pm$0.7yrs, body fat; 36.7$\pm$0.9). The walking and running protocol consisted of treadmill speeds for five min at each of the following speeds: 5.0, 5.5, 6.0, 6.5, 7.0 km.$hr^{-1}$. The obtained data reveal in group A, the rate of oxygen consumption and energy expenditure was higher during walking compared to running ate treadmill speeds $\geq$ 6.6km.$hr^{-1}$. In group 5, the rate of oxygen consumption and energy expenditure was higher during walking compared to running ate treadmill speeds $\geq$ 6.8km.$hr^{-1}$. Heart rates and respiratory exchange ratio were higher at treadmill speeds $\geq$5.8 in group A and $\geq$5.5 in group B. these findings demonstrated that a difference of percent body fat in obese women have no large effect on energy efficiency of walking, but walking within speeds 6.5~7.0km/hr resulted in rates of energy expenditure that were as high or higher than jogging at the same speeds even though the relative stress was greater during walking.

본 연구의 목적은 10명의 비만여성을 체지방율에 의해 두 그룹(A:30~35%, B:35~40%)으로 분류하여 여러 동일한 속도(5.5, 6.0, 6.5, 7.0km.$hr^{-1}$)에서 걷기와 달리기 시 에너지 소비율과 심박수, 호흡교환율, 근동원량 등을 비교하는 것이었다. 본 실험결과 트레드밀 속도증가에 따른 산소 소비량은 두 그룹모두 걷기시 비선형적으로 증가하는 경향을 나타내었으나, 달리기 시에는 선형적 증가를 나타내어 두 그룹 모두에서 속도 6.5~7km/hr내에서 걷기의 에너지 소비율이 달리기시보다 높아지는 시점을 나타내었다. 두 그룹간 비교에서 유의한 차이는 나타나지 않았으나 A그룹 보다 B그룹이 다소 낮은 속도에서 걷기의 에너지효율성이 달리기시보다 떨어지는 경향을 보였다. 심박 수의 측정결과에서는 체 지방 율이 높은 그룹이 낮은 그룹보다 높은 심박 수 반응을 보여 체 지방 율이 높을수록 운동스트레스가 커지는 결과를 보였다. 호흡교환율 또한 체 지방 율이 낮은 그룹 보다 높은 그룹에서 운동시 탄수화물의 에너지참여비율이 높게 나타나 대사적 스트레스가 높은 것으로 나타났다. 이상의 결과로써 비만여성에서 걷기와 달리기 시 체 지방 율이 높을수록 대사적 스트레스를 증가시킬 수 있는 것으로 나타났고 에너지 소비 율도 영향을 받음으로써 걷기시 에너지 효율성에 비만인간 차이가 발생될 수 있지만, 이러한 차이는 크지 않은 것으로 생각된다.
