Hip adduction and abduction strength profiles in elite and sub-elite female soccer players according to players level and leg limb-dominance

Background: Understanding the hip adduction and abduction strength in female soccer players is crucial for performance enhancement and injury prevention. This study compares the strength profiles in these muscle groups between elite and sub-elite female soccer players and assesses the impact of leg limb-dominance. Methods: A descriptive-comparative study was employed. Eighty-two female soccer players were evaluated. Isometric hip-adduction and abduction strength were measured using a handheld dynamometer. Results: Female elite and sub-elite soccer players displayed a mean and standard deviation (SD) on isometric hip-adductor strength for dominant (3.19 Nm/kg +/- 0.69 vs. 2.40 Nm/kg +/- 0.67) and non-dominant leg (3.32 Nm/kg +/- 0.76 versus 2.42 Nm/kg +/- 0.70), respectively. For isometric hip-abductor strength in elite and sub-elite players, a mean and SD of dominant (2.86 Nm/kg +/- 0.56 vs. 2.07 Nm/kg +/- 0.50) and non-dominant (2.80 Nm/kg +/- 0.59 vs. 2.04 Nm/kg +/- 0.43). In essence, elite players were stronger than sub-elite players on isometric hip-adduction (mean difference [MD] = 0.82 Nm/kg, CI95% = 0.42-1.12) and abduction (MD = 0.83 Nm/kg, CI95% = 0.54- 1.12) both in dominant and non-dominant, leg, whereas no differences existed for hip adduction:abduction ratios between groups and legs. Conclusions: Elite female athletes exhibited greater strength than sub-elite female players in both hip adduction and abduction, whereas adduction:abduction ratio values did not differ between the two groups or between different legs.
