title: Adolescent female volleyballers' (aged 13-15 years) body build classification and proficiency in competitions.
abstract: The present paper studies the body build and proficiency in the game of 74 female volleyballers aged 13-15 years from eight teams, who participated in Estonian championships. Fourteen anthropometric measurements were taken from the players, and these data were systematized into a 5 SD height-weight classification (small, medium, large, pyknomorphous and leptomorphous). The players participated in 28 matches, which were recorded in parallel with two computers equipped with the program Game. The girls' proficiency in the game was assessed in the same body build classes. For each class, the total number of serves, receptions, attacks and blocks, their mean values per player and percentage from elements performed during the whole tournament were calculated. In the same way, for each class the total number of points scored and separately the number of points scored in serve, attack and block were calculated. For each class the mean index of proficiency was calculated for serve, reception, attack and block. The results showed, that the most successful were the girls of class 3 with big height and weight. The small girls of class 1 were the least successful. The players belonging to the other classes formed an intermediate group. The authors recommend the use of the body build classification as it enables simultaneous assessment of body build and proficiency in competitions.
