摘要: Background: Endocrine mechanisms can be a determining factor in the neuromuscular performance of young athletes. Objective: The objective present study was to relate maturational and hormonal markers performance, as well verify whether athletes with different testosterone levels show differences muscle strength. Methods: sample consisted 37 male Brazilian (11.3 ± 0.94 years) who were members sports initiation project. Hormonal analyzed biochemically by blood samples, maturation mathematical models based on anthropometry. Body composition verified tetrapolar bioimpedance. upper lower limb strength body speed analyzed. Results: related (p < 0.05). Young people higher showed Artificial neural networks that predicted limbs 49%, 60%. Maturation foreshadowed 30.3%. Conclusion: Biological superior relation others.
