Body composition and resting metabolic rate (RMR) were measured in 4 spinal cord injured (SCI) paraplegic men. The level of lesion ranged from T4 to L1, and the duration of disability averaged 7.4 +/- 3.3 (SEM) years. Hydrodensitometry was used to determine percent body fat, fat mass and lean body mass (LBM). RMR was measured following a 12-hour fast and 24 hours post-exercise using a ventilated hood. RMR was also predicted from LBM values based on the equation of Cunningham (1980). Results of the body composition measurements indicated a greater than average amount of body fat for men of this age group. RMR and LBM were significantly correlated (r = 0.98, p less than 0.02). However, measured RMR values were lower than predicted in 3 of the 4 subjects, especially when LBM was relatively low. Further investigation into the relationship between LBM and RMR in SCI individuals is warranted using a larger sample size and with subjects representing a wide range of lesion level.
对4名脊髓损伤（SCI）截瘫男性进行了身体成分和静息代谢率（RMR）测量。损伤平面从T4到L1，残疾持续时间平均为7.4±3.3（标准误）年。采用水下密度测量法测定体脂百分比、脂肪量和去脂体重（LBM）。在禁食12小时和运动后24小时，使用通风面罩测量RMR。还根据坎宁安（1980年）的公式，从LBM值预测RMR。身体成分测量结果表明，该年龄组男性的体脂量高于平均水平。RMR与LBM显著相关（r = 0.98，p < 0.02）。然而，4名受试者中有3名的实测RMR值低于预测值，尤其是当LBM相对较低时。有必要使用更大的样本量并涵盖广泛损伤平面的受试者，进一步研究SCI个体中LBM与RMR之间的关系。
