Abstract
Objective: To compare lower limb strength and countermovement jump (CMJ) kinetics between elite
female footballers with and without a history of anterior cruciate ligament reconstruction (ACLR),
hamstring strain, or hip/groin injury.
Design: Cross-sectional.
Setting: Field-based.
Participants: 369 elite female Australian football, soccer and rugby league players aged 15e35.
Main outcome measures: Isometric hip adductor and abductor strength, eccentric knee flexor strength,
and CMJ vertical ground reaction forces, including between-leg asymmetry. Players reported their lifetime history of ACLR, and whether they had sustained a hamstring strain, or hip/groin injury in the
previous 12-months.
Results: Players with a unilateral history of ACLR (n ¼ 24) had significant between-leg asymmetry in
eccentric knee flexor strength (mean ¼ -6.3%, 95%CI ¼ -8.7 to -3.9%, P < .001), isometric hip abductor
strength (mean ¼ -2.5%, 95%CI ¼ -4.3 to -0.7%, P ¼ .008), and CMJ peak landing force (mean ¼ -5.5%,
95%CI ¼ -10.9 to -0.1%, P ¼ .046). Together, between-leg asymmetry in eccentric knee flexor strength,
isometric hip abductor strength, and CMJ peak landing force distinguished between players with and
without prior ACLR with 93% accuracy.
Conclusion: Elite female footballers with a history of ACLR, but not hamstring or hip/groin injury, exhibit
persistent between-leg asymmetries in lower limb strength and jump kinetics following a return to
sport.
