The paper reports on investigations on the influence of various mathematical formulations on the determination of the proportion of fat in relation to body-weight by means of skin fold measurements. For this purpose, the various equations derived from Archimedes' law, as well as the densities of various body fractions as determined by different authors, are discussed. This is followed by a discussion of the deliberations on the methods to be employed for estimating the density of the body by means of skin fold measurements. The various formulations differ from each other mainly by the location and number of measuring points. It was shown by means of comparative studies that for children aged between 9 and 16, independent of their sex, it will be sufficient to employ two skin folds (triceps and scapula). The existence of a very close correlation between the measured data of these points of measurement was found when using different calipers and the relevant conversion factors. In this manner it becomes possible to use a nomogram which has already been determined by Parízková and which was converted into a matrix for easier calculation. The determination of the relative proportion of fat'via skin fold measurements cannot replace the determination of individual body density by weighing under water. However, in mass examinations it is very well suited for differentiating between various groups of children (e.g. overweight, underweight, trained, and untrained) in respect of their relative proportion of fat.
该论文报告了关于各种数学公式对通过皮褶测量确定脂肪与体重比例的影响的研究。为此，讨论了从阿基米德定律推导出来的各种公式，以及不同作者所确定的各种身体成分的密度。接下来讨论了关于通过皮褶测量估计身体密度所采用方法的思考。各种公式的主要区别在于测量点的位置和数量。通过比较研究表明，对于9至16岁的儿童，无论性别如何，采用两个皮褶（三头肌和肩胛下）就足够了。当使用不同的卡尺和相关转换因子时，发现这些测量点的测量数据之间存在非常密切的相关性。通过这种方式，可以使用帕日茨科娃已经确定并转换为矩阵以便于计算的列线图。通过皮褶测量确定脂肪的相对比例不能替代通过水下称重确定个体身体密度。然而，在大规模检查中，它非常适合于区分不同组别的儿童（例如超重、体重不足、受过训练和未受过训练的儿童）的脂肪相对比例。
