Brazil has been the benchmark for volleyball performance for at least two decades, providing a unique context to examine expertise development. This study examined the variation in body size, functional capacities, motivation for achievement, competitiveness, and deliberate practice of youth volleyball players associated with differences in biological maturity status, chronological age, and accumulated deliberate volleyball practice, adopting a Bayesian multilevel modeling approach. We considered 68 female and 94 male adolescent players (14.2 years, 90% confidence interval: 12.7 to 16.0). Players were grouped by the onset of deliberate volleyball practice as related to biologic maturation milestones [pre-puberty deliberate practice onset (12% of the sample), mid-puberty deliberate practice onset (51% of the sample), and late-puberty deliberate practice onset (37% of the sample). There was substantial variation in body dimensions and functional performance by gender. There was no variation by gender for motivation for deliberate practice and motivation for achievement and competitiveness. The young volleyball players appeared to be highly motivated and committed to deliberate practice, achievement, and competitiveness. Alignment of chronological age, biological maturation, and accumulated training experience allow more in-depth insights into young volleyball players' development, providing sounder support for coaches´ decisions.
巴西至少在过去二十年一直是排球表现的基准，为研究专业技能的发展提供了独特的背景。本研究采用贝叶斯多层次建模方法，考察了与生物成熟度状态、实际年龄和累计专项训练相关的身体尺寸、功能能力、成就动机、竞争力和专项训练的变化情况，参与者为 68 名女性和 94 名男性青少年运动员（14.2 岁，90%置信区间：12.7 至 16.0）。根据专项训练开始时间与生物成熟里程碑的关系，运动员被分为以下几组：青春期前开始专项训练（样本的 12%）、青春期中期开始专项训练（样本的 51%）和青春期后期开始专项训练（样本的 37%）。性别间身体尺寸和功能表现存在显著差异。专项训练动机和成就动机、竞争力在性别间无差异。青少年排球运动员似乎具有高度的专项训练动机、成就动机和竞争力。实际年龄、生物成熟度和累计训练经验的协调一致，可以更深入地了解青少年排球运动员的发展情况，为教练的决策提供更有力的支持。
