To characterize energy metabolism in individuals with mental retardation (MRs), We meaured energy cost at several physical activity levels (basal, supine, siffting, standing, and walking at 30,50 and 70 m/min), maximal oxygen consumption (Vo_2max), and body composition in 23 male MRs and the same number of volunteer male controls. Both groups were individually matched for age, body height, and body weight. Energy costs were measured by the Douglas bag technique. The recently developed sulfur hexafluoride (SF_6) dilution technique was employed for measuring body composition.In addition, 3-dimensional accelerometry was used for evaluating body movements, and plasma indices of macronutrients were also measured. Results : The energy cost of MRs, when sitting, standing, and walking at 30 and 50 m/min, was significantly higher than that of controls (p<0.05), while the basal and resting metabolic rates were similar in both groups. Vo_2max was significantly lower (P<0.05) in MRs than controls. Accelerometry demonstrated excessive movements in MRs, which may explain their higher energy cost of exercise. By contrast, no significant difference was observed in percent body fat and lean body mass. Concentrations of plasma total cholesterol, triacylglycerols and albumin were significantly lower in MRs compared with controls.Our findings suggest that MRs are burdened with energy metabolism less economical than non-MRs. A limited physical activity in their daily life may be the cause. These characteristics of MRs' energy metabolism should be considered for planning their proper dietary schdules and physical activity programs

为了解智力低下（MR）个体能量代谢的特点，我们测定了23例MR和相同数量的男性志愿者在不同体力活动水平（基础、仰卧、站立、30、50和70 m/min步行）下的能量消耗、最大耗氧量（Vo_2max）和身体成分。两组在年龄、身高和体重方面均单独匹配。能量消耗用道格拉斯袋法测量。采用新近发展起来的六氟化硫（SF_6）稀释法测定体成分，用三维加速度计评价体运动，并测定血浆中大量营养素指数。结果如下：当坐着、站立和以30和50 m/min行走时，MR的能量消耗显著高于对照组（p<0.05），而两组的基础代谢率和静息代谢率相似。最大摄氧量（Vo 2 max）在二尖瓣返流组显著低于对照组（P<0.05）。加速度计显示MR的过度运动，这可能解释了他们运动的更高能量消耗。相比之下，在体脂百分比和瘦体重方面没有观察到显著差异。血浆总胆固醇、三酰甘油和白蛋白的浓度在MR患者中显著低于对照组。我们的研究结果表明，MR患者的能量代谢负担比非MR患者低，日常生活中有限的体力活动可能是原因。因此，在制定合理的膳食计划和体育锻炼计划时，应考虑代谢综合征患者能量代谢的特点
