Insufficient data are readily available concerning the vascular fluid volumes of healthy young men. The primary purpose of this study was to develop a normative database for the erythrocyte volume, plasma volume, and blood volume of healthy young men. The secondary purposes were to relate these vascular fluid volumes to the person's body size and physical fitness level and to develop equations that enable their prediction. Fifty-one male soldiers with a mean age of 22 (range 18-35) yr and with a mean maximal aerobic power of 53 (range 42-65) ml O2.kg-1.min-1 had their lean body mass and vascular fluid volumes measured. Erythrocyte volume was measured by 51Cr, and plasma volume was measured by 125I. The findings concerning the erythrocyte volume, plasma volume, and blood volume of these young men are summarized as follows: 1) these vascular fluid volumes are accurately predicted from several indices of body size; 2) lean body mass is the anthropometric index that is most closely correlated to these vascular fluid volumes; 3) the erythrocyte volumes for a given body surface area are lower, particularly for large individuals, than values previously reported in surveys of undefined populations; 4) aerobic fitness is generally not related to vascular volumes; and 5) F-cell ratio is not related to aerobic fitness.
目前关于健康青年男性血管内液体容量的可用数据不足。本研究的主要目的是建立一个健康青年男性红细胞容量、血浆容量和血容量的标准数据库。次要目的是将这些血管内液体容量与人的体型和体能水平相关联，并建立能够进行预测的方程。对51名平均年龄22岁（范围18 - 35岁）、平均最大有氧能力为53（范围42 - 65）ml O₂·kg⁻¹·min⁻¹的男性士兵测量了去脂体重和血管内液体容量。红细胞容量通过⁵¹Cr测量，血浆容量通过¹²⁵I测量。这些青年男性的红细胞容量、血浆容量和血容量的研究结果总结如下：1）这些血管内液体容量可根据多种体型指标准确预测；2）去脂体重是与这些血管内液体容量最密切相关的人体测量指标；3）对于给定的体表面积，红细胞容量较低，尤其是对于体型较大的个体，低于先前在未明确人群调查中报告的值；4）有氧适能通常与血管容量无关；5）F细胞比率与有氧适能无关。
