Description
Summary:: Mechanisms that influence muscle strength can interfere with neuromotor performance and overall health, thus hormone markers and maturation can interact in this process. Objective: The present study aimed to verify the relationship of hormonal markers and biological maturation on neuromotor abilities in young people. : This is a cross-sectional study with 44 female participants (11.5 ± 1.5 years). Hormones were analyzed biochemically. Skeletal and somatic maturation were analyzed using anthropometry. The muscular power of the upper and lower limbs, body speed with change of direction, and speed of the upper limbs were verified. : Bone age was correlated with hormonal markers (estradiol: r = 0.58; = 0.0007), (testosterone: r = 0.51; = 0.005). Peak growth velocity correlated with estradiol (r = 0.51; = 0.004). The power of the lower limbs (estradiol: r = 0.52; = 0.006; testosterone: r = 0.42; = 0.03) and of the upper limbs (estradiol: r = 0.51; = 0.007; testosterone: r = 0.42; = 0.02) had a positive correlation with hormone levels and had similar results with maturation. The analysis by artificial neural networks indicated that the maturation can predict the neuromotor performance between 57.4% and 76%, while the hormonal markers showed a potential of more than 95% for the foreshadowing of the neuromotor performance of the upper limbs. : It was possible to conclude that the hormones had a relationship with maturational development and bone age in female subjects.
