Study on the correlation between lower limb joint muscle strength and balance ability among female college students in soccer

Abstract To study the correlation between lower limb joint muscle strength at different angular velocities and dynamic balance among college students in soccer. Methods: 30 college students from Zunyi Medical University had a regular football training more than 16 weeks. The ISO-MED2000 was used to test the peak flexion and extension torque of the hip, knee and ankle at different angular velocities, and the Y-Balance Test was used to test the dynamic balance of lower extremities. Results: The relative peak of hip flexion and extension was associated well with balance ability at an angular velocity of 180°/ s; the relative peak torque of flexion and extension of the knee was well correlated with the balance ability at 30°/ s and 180°/ s (P>0.01); the ankle flexion was well correlated with balance ability at 30°/ s and 90°/ s(P>0.01). Conclusions: Muscular strength of lower extremities play different effects on dynamic balance ability at different velocity.
