The aims of this study were to detect biological maturity and certain athletic skills in boys aged 14 participating in competitive basketball, and to compare certain athletic skills of participants according to their biological maturity status. The participants were most talented Serbian basketball players (n= 49) who were divided into three groups according to their maturity status: early (n= 14), average (n= 24) and late maturing (n= 11). Biological maturity status of participants was assessed by technique developed by Mirwald et al. (2002). Nine tests of basic athletic skills: vertical jump, medicine ball throwing, run at 20, 30 and 50 m, agility t-test, zigzag agility drill, agility run 4x15 m, the line drill, as well as four basketball skills field tests (speed spot shooting, passing, control dribble and defensive movement) were applied. The results of this study showed that the three groups of subjects differed in applied variables (p <0.05). Average maturers achieved the best results in almost all variables, while late maturers achieved the worst results. Early maturers achieved the best results only in one variable - medicine ball throwing. Only harmonized chronological and biological age, i.e. chronological and biological growth and development, enable the best demonstration of motor abilities based on morphological characteristics.

KEY WORDS: Chronological age; Biological age; Motor abilities; Basketball skills.
