Running biomechanics in football players with and without hip and groin pain. A cross-sectional analysis of 116 sub-elite players

Abstract

Objective: Examine whether football players with hip and/or groin (hip/groin) pain have impaired running biomechanics when compared to pain-free players, analysing men and women independently. Design: Cross-sectional. Setting: Biomechanics laboratory. Participants: Seventy-eight (62 men, 16 women) football players with >6months of hip/groin pain and a positive flexion-adduction-internal rotation test and 38 (25 men, 13 women) asymptomatic players. Main outcome measures: Pelvis angles and hip, knee, and ankle joint angles and moments were analysed during the stance phase of overground running at 3–3.5 m⋅s−1. Continuous joint angle and moment data were compared between symptomatic and asymptom..
