Abstract
The aim of this study is to determine existence and the amount of deviation of morphological features in relation to dominant/ non dominant upper limb. The sample subjects were 30 healthy male tennis players (age: 12.45 ± 1.12). They were measured by 7 morphological measures. The aim of this testing was to collect information about differences between dominant and non-dominant arm of a player. Obtained results indicate that results of dominant arm are statistically and significantly different (p < 0.01) from results of non-dominant arm (in all variables), Due to unilaterality of the sport, tennis players have predisposition to develop certain morphological asymmetry. However, it is necessary to delay development and to work on development of non-dominant side of the body (through quality training) and to prevent injuries in that way.
