Growth and maturation are central concerns in the organization of training and competitions in youth sports. This study examined maturity-associated variation in body size and adiposity among adolescent girls participating in competitive age group youth soccer. The sample included 441 players 10.08-16.73 years of age. Stature and body mass were measured and body composition was predicted. The Fels method was used to estimate skeletal age. Skeletally maturity status (late, average or early maturing) was based on the difference between chronological and skeletal age for each player. Mean stature approximated the 50 percentiles of the general population in all competitive age groups, while mean weight fluctuated between 50 and 75 percentiles. Age- and maturity-specific means for estimated fat mass ranged between 18.0% and 28.2%. The number of players classified as skeletally mature increased with competitive age groups (under-13: 0%; under-15: 8%; under-17: 49%). In general, early maturing girls tended to be heavier than their age group peers and especially when compared to late maturing players.
生长和成熟是青少年体育训练和竞赛组织的核心关注点。本研究考察了参加竞技年龄组青少年足球比赛的青春期女孩的成熟相关的身体大小和体脂变化。样本包括 441 名 10.08-16.73 岁的运动员。测量了身高和体重，并预测了身体成分。Fels 法用于估计骨骼年龄。根据每个运动员的骨龄和实际年龄之间的差异，将骨骼成熟状态（晚熟、平均或早熟）进行分类。在所有竞技年龄组中，平均身高接近总人口的 50%，而平均体重在 50%到 75%之间波动。按年龄和成熟度分类的估计体脂平均值在 18.0%到 28.2%之间。被归类为骨骼成熟的运动员人数随着竞技年龄组的增加而增加（13 岁以下：0%；15 岁以下：8%；17 岁以下：49%）。一般来说，早熟的女孩往往比同龄的女孩更重，尤其是与晚熟的运动员相比。
