For this work were taken measurements of the skinfolds of Russian children and adolescents of both sexes 7-17 years old, with a total number of 1103 pupils. Was made a comparison of the mean values of the average skinfolds. Results and discussion. In the investigated group significant differences in the average thickness of the skinfolds were revealed between the initial set of Matiegka and the modification of Lutovinova et al. The revealed differences significantly influenced the final estimates of the mass of body fat. However, the estimates obtained turned out to be highly correlated and with a high level of agreement, on the basis of which conversion formulas between them were proposed. Conclusion. When using Matiegka's formulas, it is necessary to give a detailed description of the method for measuring skinfolds, taking into account the influence of the choice of skinfolds on the final estimate of the fat mass.

About the using of Matiegka’s formulas to evaluate the fat component of body mass. Technical recommendations (short communication)
