THE RATIO BETWEEN THE LENGTH OF UPPER AND DOWN PARTS OF THE BODY IN THE CROSS-SECTION OF THE EQUAL TORQUES APPEARS AS AN ANATOMICAL CONSTANT

Abstract

The bed scales determine the section, in which the torques of the upper and the down body parts are balanced. In this section the length and mass of the upper and down parts of the body were measured. Aim of the study: To investigate the ratio between the length of the upper and down part of the body in the cross-section of the equal torques of the upper and the down bodily parts. Results: 62 people between the ages of 18 and 28 were examined. The ratio Hup /Hdown in the cross-section of the equal torques of the upper and down bodily parts don’t depend from body height H and is equals to: Hup /Hdown =0.791 H (i.e. Hup /Hdown ~0.8 H). Conclusions: The ratio between the length of upper and down parts of the body in the crosssection of the equal torques of upper and lower bodily parts appears nearly an anatomical constant.
