J Strength Cond Res 32(2): 297-303, 2018-Maturation status is a confounding factor when identifying talent in elite youth soccer players (ESP). By comparing performance of ESP and control participants (CON) matched for maturation status, the aims of our study were to establish the importance of acceleration, sprint, horizontal-forward jump, and vertical jump capabilities for determining elite soccer playing status at different stages of maturation. Elite youth soccer players (n = 213; age, 14.0 ± 3.5 years) and CON (n = 113; age, 15.0 ± 4.4 years) were grouped using years from/to predicted peak height velocity (PHV) to determine maturation status (ESP: pre-PHV, n = 100; mid-PHV, n = 25; post-PHV, n = 88; CON: pre-PHV, n = 44; mid-PHV, n = 15; post-PHV, n = 54). Participants performed 3 reps of 10- and 20-m sprint, bilateral vertical countermovement jump (BV CMJ), and bilateral horizontal-forward CMJ (BH CMJ). Elite youth soccer players demonstrated faster 10-m (p < 0.001) and 20-m sprint (p < 0.001) performance than CON at all stages of maturation. Mid-PHV and post-PHV ESP achieved greater BV CMJ height (p < 0.001) and BH CMJ distance (ESP vs. CON; mid-PHV: 164.32 ± 12.75 vs. 136.53 ± 21.96 cm; post-PHV: 197.57 ± 17.05 vs. 168.06 ± 18.50 cm; p < 0.001) compared with CON, but there was no difference in BV or BH CMJ between pre-PHV ESP and CON. Although 10 and 20 m and sprint performance may be determinants of elite soccer playing status at all stages of maturation, horizontal-forward and vertical jumping capabilities only discriminate ESP from CON participants at mid- and post-PHV. Our data therefore suggest that soccer talent identification protocols should include sprint, but not jump assessments in pre-PHV players.
莫尔塔格、布朗利、奥布赖恩、摩根斯、德鲁斯特和埃斯金。在精英青年足球中，速度和力量的重要性取决于成熟度。《力量与 Conditioning 研究》32(2):297-303，2018-成熟度是识别精英青年足球运动员(ESP)人才的一个混杂因素。通过比较 ESP 和对照组( CON )参与者在成熟度匹配时的表现，我们研究的目的是确定加速、冲刺、水平向前跳跃和垂直跳跃能力在不同成熟阶段对确定精英足球比赛状态的重要性。精英青年足球运动员(n = 213;年龄 14.0 ± 3.5 岁)和 CON(n = 113;年龄 15.0 ± 4.4 岁)根据从预测高峰身高速度(PHV)到确定成熟度状态的年份分组(ESP:预 PHV，n = 100;中 PHV，n = 25;后 PHV，n = 88;CON:预 PHV，n = 44;中 PHV，n = 15;后 PHV，n = 54)。参与者进行了 3 次 10 米和 20 米冲刺、双侧垂直反跳( BV CMJ )和双侧水平向前反跳( BH CMJ )。在所有成熟阶段，精英青年足球运动员的 10 米(p < 0.001)和 20 米冲刺(p < 0.001)速度均快于 CON。中 PHV 和后 PHV ESP 实现了更大的 BV CMJ 高度(p < 0.001)和 BH CMJ 距离(ESP 与 CON;中 PHV:164.32 ± 12.75 与 136.53 ± 21.96 cm;后 PHV:197.57 ± 17.05 与 168.06 ± 18.50 cm;p < 0.001)与 CON 相比，但在 PHV 前 ESP 和 CON 之间，BV 或 BH CMJ 没有差异。尽管 10 米和 20 米和冲刺表现可能是所有成熟阶段精英足球比赛状态的决定因素，但水平向前和垂直跳跃能力仅在中 PHV 和后 PHV 时区分 ESP 和 CON 参与者。因此，我们的数据表明，足球人才识别协议应包括冲刺，但在 PHV 前球员中不包括跳跃评估。
