To investigate the differences in hip adductor and abductor muscle strength in elite male footballers from youth to senior level.
We tested 125 players from the under-13-years (U'13) to senior squads of a Danish male professional football club in this cross-sectional design study. Hip adductor and abductor force (in newtons), torque (in newton meters), normalized torque (in newton meters per body mass), and adduction-to-abduction ratio were measured using handheld dynamometry.
Between U'13 and senior level, adductor force increased by 104%, torque by 127%, and normalized torque by 21%. Abductor force increased by 78%, torque by 126%, and normalized torque by 17%. For incremental differences between age groups, significant increases were observed between the ages of U'13 to U'14 (18%-39%) and U'14 to U'15 (19%-33%) for all strength measures (P ≤ .021). No incremental difference was observed for adductor-to-abductor ratio.
The large increases in hip adductor and abductor strength occurring between the ages of U'13 and U'15 offer insight into the strength capabilities and stress demands in these players, which may relate to injury vulnerability, and facilitate clinicians in selecting best-suited exercise interventions.
研究精英男性足球运动员从青年到成年阶段髋内收肌和外展肌力量的差异。
在这项横断面设计研究中，我们测试了丹麦一家男性职业足球俱乐部从13岁以下（U'13）到成年队的125名球员。使用手持式测力计测量髋内收肌和外展肌力量（以牛顿为单位）、扭矩（以牛顿米为单位）、标准化扭矩（以牛顿米每体重为单位）以及内收与外展比率。
从U'13到成年阶段，内收肌力量增加了104%，扭矩增加了127%，标准化扭矩增加了21%。外展肌力量增加了78%，扭矩增加了126%，标准化扭矩增加了17%。对于各年龄组之间的增量差异，在所有力量测量指标上，U'13至U'14岁（18%-39%）和U'14至U'15岁（19%-33%）之间观察到显著增加（P≤0.021）。内收与外展比率未观察到增量差异。
U'13至U'15岁之间髋内收肌和外展肌力量的大幅增加，为了解这些球员的力量能力和压力需求提供了见解，这可能与受伤易感性有关，并有助于临床医生选择最合适的运动干预措施。
