The cardiac volume in decubitus was measured by Rohrer radiological method in 229 subjects, of which 150 were children of both sexes, aged 4 to 16 and 79 were adult males, 17 to 50 years old. Anthropometric parameters and maximum O2 consumption were also measured. Considering that the size of thorax in Ivory Coast natives is significantly smaller than that of a Caucasian, an eventual influence over the cardiac volume was looked for. Results showed that: -- in the child, the cardiac, volume increased linearly with age: 162 ml at 4 and 680 ml at 16; -- significant positive correlations were found between the cardiac volume, the body-weight andusrface, and the measurements of the thorax; -- when compared to data found in the literature, the cardiac volumes of children and adults of the Ivory Coast in relation with the body weight or surface are lower than the values found in Caucasians; -- children who have been swimming for two years and adults from the national swimming team have a cardiac volume significantly superior to that of Ivory controls; for these subjects, results are equivalent to those of Caucasians; -- there is a highly significant positive correlation between the cardiac volume and the maximum oxygen consumption. To compare values of cardiac volume in different populations, it is necessary that the groups of subjects be very homogeneous and have a comparable level of activity.
采用罗勒放射学方法对229名受试者的卧位心脏容积进行了测量，其中150名是4至16岁的儿童，79名是17至50岁的成年男性。还测量了人体测量参数和最大耗氧量。鉴于象牙海岸当地人的胸廓尺寸明显小于白种人，因此研究了其对心脏容积的潜在影响。结果表明：——在儿童中，心脏容积随年龄呈线性增加：4岁时为162毫升，16岁时为680毫升；——心脏容积、体重、体表面积与胸廓测量值之间存在显著正相关；——与文献中的数据相比，象牙海岸儿童和成人的心脏容积与体重或体表面积的关系低于白种人；——游泳两年的儿童和国家游泳队的成年人的心脏容积明显高于象牙海岸对照组；对于这些受试者，结果与白种人相当；——心脏容积与最大耗氧量之间存在高度显著的正相关。为了比较不同人群的心脏容积值，受试者组必须非常同质且具有可比的活动水平。
