[Morphologic features of the structure of the hand bones of young volley ball players].

By means of roentgenography method with subsequent roentgenogramometry and roentgenodensitometry, morphological peculiarities of structure and mineralization of the hand bones in sportsmen-volley-ball players and in schoolchildren who do not go in for sports, at the age of 14-19 years have been studied. Systematic training in volley-ball produces certain increase in dimentions of the hand bones, prolongation of their synostosis time, intensification in development of the sesamoid bones and increasing amount of mineral salts in their bones.
