The aim of the work was to elucidate experimentally the influence of different in intencity and character physical loadings on the growth of the femoral bones in 110 albino rats. A positive, but not synonymous, influence of dynamic and static loadings on the growth of the femoral bones in the experimental animals was proved. Long-lasting dynamic loadings stimulate the increment of mass, length and massivity of the femoral bones in the albino rats, the phenomenon was especially prominent in the experimental group under training regimen every other day. Static loading contributes to the femoral bone growth only at the first stage of the experiment. Prolonged static loading inhibits the growth of the femoral bones throughout all the parameters studied.
