Dynamic hip stabilizers are essential for optimal performance in football players, particularly during kicking. Although the muscle strength deficits of hip muscles as an etiology of osteitis pubis (OP) in football players have not yet been well investigated, previous assessments give more attention to the concentric mode of strength for both hip flexor and extensor muscles. Functionally, the hip muscles interact in an eccentric/concentric pattern. This study aimed to compare the concentric, eccentric, and eccentric antagonist/concentric agonist ratios for hip flexor and extensor strength between football players with OP and healthy athletes.
Thirty-four male footballers with OP and eighteen healthy footballers were tested using an isokinetic dynamometer at a speed of 180°/s.
Football players with osteitis pubis demonstrated a significantly lower eccentric extensor/concentric flexor ratio and higher eccentric hip flexor/extensor ratio (p < 0.05) when compared with healthy participants.
The present study demonstrated that football players with OP had a reduced capability to produce eccentric hip extension torque compared to healthy athletes. Consequently, the eccentric rather than the concentric weakness of hip extensors could be suggested as one of the intrinsic contributing factors for OP. Incorporating findings of the current study in clinical practice could afford critical information while evaluating the hip muscles in football players with OP for pre-screening, developing rehabilitation programs, and guiding the decision to return to sports after injury.
动态髋关节稳定器对于足球运动员的最佳表现至关重要，尤其是在踢球时。尽管髋关节肌肉力量不足是足球运动员耻骨炎（OP）的病因尚未得到充分研究，但之前的评估更关注髋关节屈肌和伸肌的向心强度模式。在功能上，髋关节肌肉以离心/向心的模式相互作用。本研究旨在比较 OP 足球运动员和健康运动员的髋关节屈肌和伸肌的向心、离心和离心拮抗/向心协同比值。
使用 180°/s 的等速测力仪对 34 名患有耻骨炎的男性足球运动员和 18 名健康足球运动员进行测试。
与健康参与者相比，患有耻骨炎的足球运动员的离心伸肌/向心屈肌比值显著降低，而离心髋关节屈肌/伸肌比值显著升高（p<0.05）。
本研究表明，OP 足球运动员产生离心髋关节伸展扭矩的能力较健康运动员降低。因此，髋关节伸肌的离心而不是向心无力可能被认为是 OP 的一个内在致病因素之一。在临床实践中纳入本研究的结果，可以在评估 OP 足球运动员的髋关节肌肉时提供关键信息，用于进行预筛查、制定康复计划，并指导受伤后重返运动的决策。
