Chest diameters in the body mass forecast

Two other body mass indices have been studied in the paper, by means of which the density is to measure human body has on the surface and in the volume of the hypothetic cylinder with the height equal to that of stature and with the circumference computed from the transverse and sagittal diameters of the chest. Thus we have to do with a modification of the procedure where the width and depth of chest were given by its circumference (mesosternale). The reason which made this modification interesting for us was in that the measurement of the transverse and sagittal diameter of the chest did not depend--when compared with the chest circumference measurement--so much on the muscular and fat tissue of the human body. Both these body mass indices have been used also to forecast body mass adequate to the respective skeletal space--surface and volume of the cylinder constructed by means of the dimensions of the skeleton: stature and transverse and sagittal diameter of the chest. Prediction efficiency of both these formulas has been verified numerically by means of an extensive data material of the Czechoslovak Spartakiade 1985, in dependence on sex and age. Information contribution of the chest diameters in the adequate body mass forecast proved to be doubtless. Besides it the possibility has been discussed to increase prediction reliability of body mass by combining both procedures under consideration with respect to the values of skeletal dimensions of the respective proband.
