Emmonds, S, Scantlebury, S, Murray, E, Turner, L, Robsinon, C, and Jones, B. Physical characteristics of elite youth female soccer players characterized by maturity status. J Strength Cond Res 34(8): 2321-2328, 2020-The purpose of this study was to investigate the influence of maturity status on the physical characteristics of youth female soccer players. One hundred fifty-seven players from 3 elite soccer academies in England completed assessments of anthropometry, strength (isometric midthigh pull), lower-body power (countermovement jump [CMJ]), aerobic capacity (Yo-Yo intermittent recovery test level 1), change of direction (CoD: 505-left/right), and speed (10 and 30 m). Each player was classified into 1 of 6 maturity groups based on their estimated years from peak height velocity (YPHV). Magnitude-based inferences were used to assess for the practical significance between consecutive groups. Speed, CoD time, CMJ, and aerobic capacity were all possibly most likely better in more mature players. However, there was a likely difference in relative peak force between maturity groups -0.5 YPHV (27.13 ± 4.24 N·Kg) and 0.5 YPHV (24.62 ± 3.70 N·Kg), which was associated with a likely difference in 10-m sprint time (-0.5 YPHV: 2.00 ± 0.12 vs. 0.5 YPHV 2.08 ± 0.16 seconds) and unclear changes in CMJ and CoD time. Findings provide novel comparative data for this cohort relative to maturity status and can be used by strength and conditioning coaches to inform the design of training programs for youth female soccer players. Strength and conditioning coaches should be aware that youth female soccer players may experience a decrease in relative strength around peak height velocity, which may impact upon the speed, CoD time, and CMJ of players.
埃蒙兹、斯坎特伯里、默里、特纳、罗宾逊和琼斯。根据成熟度状态描述精英青年女足运动员的身体特征。《力量与调节研究杂志》34(8)：2321-2328，2020-本研究旨在探讨成熟度状态对青年女足运动员身体特征的影响。来自英国 3 家精英足球学院的 157 名球员完成了人体测量学、力量（等长大腿拉力）、下肢力量（纵跳）、有氧能力（Yo-Yo 间歇性恢复测试 1 级）、变向能力（505-左/右）和速度（10 米和 30 米）的评估。根据估计的从峰值身高速度到 YPHV 所需的年数，每位球员都被分类到 6 个成熟组中的 1 个。基于幅度的推理用于评估连续组之间的实际意义。速度、CoD 时间、CMJ 和有氧能力在更成熟的球员中都可能更好。然而，在相对峰值力方面，成熟组之间存在一个可能的差异——0.5 YPHV（27.13±4.24N·kg）和 0.5 YPHV（24.62±3.70N·kg），这与 10 米冲刺时间的可能差异相关（0.5 YPHV：2.00±0.12 秒；0.5 YPHV：2.08±0.16 秒），CMJ 和 CoD 时间的变化不明显。研究结果为该队列提供了与成熟度状态相关的新的比较数据，可由力量和调节教练用于指导青年女足运动员训练计划的设计。力量和调节教练应该意识到，青年女足运动员可能在峰值身高速度时经历相对力量的下降，这可能会影响球员的速度、CoD 时间和 CMJ。
