Introduction: Sport activities were adopted as more frequent over time, and volleyball followed this growth, with this, the science of sports more often investigates its physiological or psychological effects. Objectives: This study aims to evaluate the main influences of bone maturation on the physical abilities of boys and girls in children practicing volleyball. Materials and Methods: The research is descriptive with a comparative characteristic, being a transversal research, anthropometric measurements and measurement of bone age by hand and pulse x-ray, motor tests of agility, coordination and strength of the lower and upper limbs. Results: a normal maturity stage was found in 50% of the children, 35% with previous and 15% later. In addition, children of the normal or accelerated stage presented better results in the physical valences. Thus, in the late maturation stage, children perform better in agility, coordination and strength. Discussion: This finding can be explained through the study (Robert Malina, 2009), which reported that the onset and maturational rhythm succeeds in a varied way in girls. That is, the event of puberty occurs differently in relation to chronological age and biological age. In addition, data on the influence of bone maturation on the selection of athletes were found, thus reducing the selection of athletes by chronological age alone. Conclusion: Children in the later stage of maturation of both sexes have better results than other children in normal and previous stages.
