A maturity-associated gradient among adolescent athletes in many sports tends to favour early maturing participants. This study was aimed to describe inter-individual variance in growth and skeletal maturation among male youth table tennis. The sample included 99 players registered in competitive clubs for at least 2 years. Chronological age (CA) ranged 10.00-14.63 years. Stature and body mass were plotted relative to US references. Skeletal age (SA) was estimated with the Fels method. Maturity status was given as SA minus CA. Somatic maturation was derived from predicted age at peak height velocity. Mean values for stature and weight were above the reference medians from 10 to 13 years and at the median in the oldest group. In general, SA was in advance to CA (CA: 12.45 ± 1.28 years; SA: 13.44 ± 2.37 years). The majority of the players were early maturing according to SA (52%) and average maturing based on the somatic indicator (80%). The results suggested that table tennis tends to retain taller and heavier participants who are somewhat advanced in skeletal maturity. Participation in youth table tennis and opportunities to win need to consider age- and maturity-associated variations, particularly regarding bands for competitions.
在许多运动项目中，青少年运动员存在着一种与成熟相关的梯度，这有利于早期成熟的参与者。本研究旨在描述男性青少年乒乓球运动员个体间生长和骨骼成熟的差异。样本包括 99 名在竞技俱乐部注册至少 2 年的运动员。他们的实际年龄（CA）在 10.00-14.63 岁之间。身高和体重与美国参考值相对应。骨骼年龄（SA）采用 Fels 法进行评估。成熟度状态表示为 SA 减去 CA。身体成熟度由预测的最大身高速度年龄得出。10 至 13 岁组的身高和体重均值高于参考中位数，而在年龄最大的组中则处于中位数。一般来说，SA 比 CA 提前（CA：12.45 ± 1.28 岁；SA：13.44 ± 2.37 岁）。根据 SA（52%）和基于体测指标的平均成熟度（80%），大多数运动员都属于早熟。研究结果表明，乒乓球运动倾向于保留那些身高较高、体重较大且骨骼成熟度略高的运动员。在青年乒乓球运动和获胜机会中，需要考虑与年龄和成熟度相关的变化，特别是与比赛分组有关的变化。
