Human body growth means structural changes of human body, whereas development means its functional changes. The purpose of this study was to study the influence of different sports in bodily growth of the young athletes. In order to analyze the influence of different sports profiles on human physical growth, in this study, 3011 footballers and 393 basketball players were tested. Two groups of athletes, according to their ages have been separated in four groups (ages 13,14,15 and 16 years old). The evaluation of bodily growth of young athletes has been tested based on changes of nine morphometrical variables. The data obtained were analyzed in terms of basic statistical parameters, whilst the differences between independent groups were analyzed by T-test and Discriminant Canonical Analysis. Statistically significant differences that have been proved, between sportsmen's measured groups, lead us to conclude that in this phase of the sportsmen's life, when their organism is in the intensive changeable puberty phase, the external factors, such as basketball elements (jumping and running), have more influence on morphometrical growth factors of young basketball players, compared with the influence of football elements on young footballers (mainly running elements). Even though, longitudinal dimension is controlled about 98% by genotype, whereas transversal dimensions account for about 93%, it is interesting that in our study longitudinal dimension has been most influenced by basketball elements, compared with transversal dimension. As a conclusion of this study, a fact could be, that even though human bodily growth is controlled over 90% by genetic factor, if external factors such as external acts occur during the sensitive and intensive phase of bodily growth, their effect may be very important.
