代谢病房的体力活动的能量成本来自于代谢病房维持体重的能量需求和56名非糖尿病男性受试者在呼吸室中测量的久坐24小时能量消耗之间的差异。 体力活动成本与体重呈负相关（r =-0.67，P < 0.0001），与体脂百分比呈负相关（r =-0.48，P < 0.0005）。 在一个15人的严格体重稳定性（每日体重变化率< +/-35 g/d）的亚组中，观察到活动能量消耗与体重（r =-0.61，P < 0.01）和体脂百分比（r =-0.51，P = 0.05）之间类似的负相关。 运动能量消耗与体重、体脂率呈负相关（r =-0.74，P = 0.002），与运动能量消耗呈负相关（r =-0.61，P = 0.002）。 这些结果表明，较重的受试者在代谢病房是不太活跃，花费更少的能量在体力活动比轻的受试者。
The energy cost of physical activity on a metabolic ward was derived from the difference between the energy requirement to maintain body weight on a metabolic ward and sedentary 24-h energy expenditure measured in a respiratory chamber in 56 nondiabetic male subjects. The cost of physical activity was negatively correlated with body weight (r = -0.67, P < 0.0001) and with percent body fat (r = -0.48, P < 0.0005). In a subgroup of 15 subjects selected for strict weight stability (rate of daily weight change < +/- 35 g/d), similar negative correlations were observed between energy cost of activity and body weight (r = -0.61, P < 0.01) and percent body fat (r = -0.51, P = 0.05). The ratio of active to sedentary energy expenditure, an index of physical activity, was also negatively correlated with body weight and percent body fat (r = -0.74, P < 0.002) and r = -0.61, P < 0.02, respectively). These results suggest that heavier subjects on a metabolic ward are less active and expend less energy in physical activity than do lighter subjects.
