: 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.
:影响肌肉力量的机制会干扰神经运动表现和整体健康,因此激素标志物和成熟度可以在这个过程中相互作用。目的:本研究旨在验证激素标志物和生物成熟度与年轻人神经运动能力的关系。:这是一项横断面研究,共有 44 名女性参与者(11.5 ± 1.5 岁)。生物化学分析了激素。使用人体测量学分析骨骼和躯体成熟度。验证了上下肢肌肉力量、身体变向速度和上肢速度。:骨龄与激素标志物(雌二醇:r = 0.58; = 0.0007)、(睾酮:r = 0.51; = 0.005)呈正相关。生长高峰速度与雌二醇呈正相关(r = 0.51; = 0.004)。下肢力量(雌二醇:r = 0.52; = 0.006;睾酮:r = 0.42; = 0.03)和上肢力量(雌二醇:r = 0.51; = 0.007;睾酮:r = 0.42; = 0.02)与激素水平呈正相关,与成熟度的结果相似。人工神经网络分析表明,成熟度可以预测神经运动表现,预测准确率在 57.4%至 76%之间,而激素标志物对上肢神经运动表现的预测潜力超过 95%。:可以得出结论,激素与女性受试者的发育成熟和骨龄有关。
