Sanz, A, Pablos, C, Ballester, R, Sanchez-Alarcos, JV, and Huertas, F. Range of motion and injury occurrence in elite Spanish soccer academies. Not only a hamstring shortening-related problem. J Strength Cond Res 34(7): 1924-1932, 2020-Age-related development of range of motion (ROM) during an active hip flexion (active straight leg raise) and its relationship with hamstring injury occurrence were examined in 1657 young male soccer players (9-18 years of age). Age-related differences in ROM showed a significant decrease from U9 to U11 (p = 0.001), from U11 to U13 (p < 0.005), and from U9 to U13 (p < 0.001), whereas ROM increased from U13 to U15 and from U13 to U18 (both p's < 0.001). Interestingly, younger and older players reached similar ROM values (U9-U18, p = 0.87). Higher ROM was found in dominant than nondominant leg in all age groups (all ps < 0.001). No differences related to playing position were found on ROM (all ps > 0.478). During the follow-up period (11 months) 97 hamstring injuries were reported showing higher rates in the older age groups (p < 0.001) and outfield players (p < 0.001). Remarkably, no differences in ROM average were found between injured players and noninjured players (p = 0.152). Our results suggest that ROM during hip flexion does not only depend on the hamstrings shortening but also on the variables related to joint stability, motor control, and hip flexor muscle weakness. Sport scientists in youth sport soccer academies should develop age-specific screening and action plans to develop strength, motor control, and flexibility to optimize ROM and reduce injuries from the grassroots stages.
桑兹、A、帕布罗斯、C、巴利斯特、R、桑切斯-阿拉尔科斯、JV 和胡尔塔斯、F. 西班牙精英足球学院的运动范围和受伤发生率。不仅与腿筋缩短有关。J 力量与条件研究 34(7):1924-1932,2020-在一项主动髋关节屈曲（主动直腿抬高）期间，与年龄相关的运动范围（ROM）的发展及其与腿筋受伤发生率的关系在 1657 名年轻男性足球运动员（9-18 岁）中进行了检查。ROM 的年龄相关差异显示，从 U9 到 U11（p = 0.001）、从 U11 到 U13（p < 0.005）和从 U9 到 U13（p < 0.001）均有显著下降，而从 U13 到 U15 和从 U13 到 U18（均为 p < 0.001）ROM 增加。有趣的是，年轻和年长的球员达到了相似的 ROM 值（U9-U18，p = 0.87）。在所有年龄组中，优势腿的 ROM 都高于非优势腿（所有 p < 0.001）。在 ROM 方面没有发现与比赛位置相关的差异（所有 p > 0.478）。在随访期间（11 个月）报告了 97 例腿筋受伤，年龄较大的年龄组（p < 0.001）和外场球员（p < 0.001）的发生率更高。值得注意的是，受伤球员和未受伤球员的 ROM 平均值之间没有差异（p = 0.152）。我们的结果表明，髋关节屈曲时的 ROM 不仅取决于腿筋缩短，还取决于与关节稳定性、运动控制和髋关节屈肌力量相关的变量。青年足球学院的运动科学家应该制定特定于年龄的筛查和行动计划，以发展力量、运动控制和灵活性，优化 ROM 并从基层阶段减少受伤。
