This study aimed to evaluate the differences in lower-limb biomechanics between adult subelite competitive football players with and without hip-related pain during two contrasting tasks-walking and single-leg drop jump (SLDJ)-and to determine whether potential differences, if present, are sex dependent.
Eighty-eight football players with hip-related pain (23 women, 65 men) and 30 asymptomatic control football players (13 women, 17 men) who were currently participating in competitive sport were recruited. Biomechanical data were collected for the stance phase of walking and SLDJ. Pelvis, hip, knee, and ankle angles, as well as the impulse of the external joint moments, were calculated. Differences between groups and sex-specific effects were calculated using linear regression models.
Compared with their asymptomatic counterparts, football players with hip-related pain displayed a lower average pelvic drop angle during walking (P = 0.03) and a greater average pelvic hike angle during SLDJ (P < 0.05). Men with hip-related pain displayed a smaller total range of motion (excursion) for the transverse plane pelvis angle (P = 0.03) and a smaller impulse of the hip external rotation moment (P < 0.01) during walking compared with asymptomatic men. Women with hip-related pain displayed a greater total range of motion (excursion) for the sagittal plane knee angle (P = 0.01) during walking compared with asymptomatic women.
Overall, few differences were observed in lower-limb biomechanics between football players with and without hip-related pain, irrespective of the task. This outcome suggests that, despite the presence of symptoms, impairments in lower-limb biomechanics during function do not appear to be a prominent feature of people with hip-related pain who are still participating in sport.
本研究旨在评估在两种对比任务（行走和单腿跳落（SLDJ））中，患有与髋关节相关疼痛的成年亚精英竞技足球运动员与无髋关节相关疼痛的运动员之间下肢生物力学的差异，并确定是否存在潜在差异，如果存在，是否存在性别依赖性。
共招募了 88 名患有与髋关节相关疼痛的足球运动员（23 名女性，65 名男性）和 30 名无症状的对照足球运动员（13 名女性，17 名男性），这些运动员目前都参加竞技运动。收集了行走和 SLDJ 支撑相阶段的生物力学数据。计算了骨盆、髋关节、膝关节和踝关节的角度以及外关节力矩的冲量。使用线性回归模型计算了组间差异和性别特异性效应。
与无症状对照组相比，患有与髋关节相关疼痛的足球运动员在行走时的平均骨盆下降角度较低（P = 0.03），在 SLDJ 时的平均骨盆提升角度较大（P < 0.05）。与无症状男性相比，患有与髋关节相关疼痛的男性在行走时的横平面骨盆角度总活动范围（行程）较小（P = 0.03），髋关节外旋力矩的冲量较小（P < 0.01）。与无症状女性相比，患有与髋关节相关疼痛的女性在行走时的矢状面膝关节角度总活动范围（行程）较大（P = 0.01）。
总体而言，无论任务如何，患有与髋关节相关疼痛的足球运动员与无髋关节相关疼痛的运动员之间的下肢生物力学差异较小。这一结果表明，尽管存在症状，但在功能活动中下肢生物力学的损伤似乎不是仍在参加运动的与髋关节相关疼痛患者的一个突出特征。
