[The correlation of the segments of the extremities as a biomechanical constant in man and mammals].
The length of human extremity segments at different stages of age development, beginning from newborns up to far-advanced age, was studied. Under examination there were 1505 humans. In addition, bone segments of the extremities were studied in 100 human skeletons and 225 skeletons of mammals from 8 orders. On the basis of a functional analysis of the length of bone segments and the detected high correlative dependence two homogeneous (homodynamic) pairs in extremities of the man and animals were identified mainly performing the supporting, static and repulsive functions. An equality between the length of these pairs was established called the biomechanical constant. The biomechanical constant regulates the proportionality of bone links as a mechanical lever in the process of age development of man as well as in the process of evolution of mammals in changing the types of locomotion from foot-walking up to phalanx-walking.
