Description
Summary:To assess a relationship between lower limb muscle activity and the frontal plane knee kinematics during a single-legged drop jump. Correlation study; Functional Anatomy Laboratory. 35 healthy collegiate male athletes. Muscle activity (%MVIC) of gluteus maximus, gluteus medius, biceps femoris, semitendinosus, vastus medialis quadriceps, vastus lateralis quadriceps, medial gastrocnemius and lateral gastrocnemius; peak knee frontal plane projection angle; and Pearson's correlation coefficients between muscle activity and peak knee frontal plane projection angle. All outcomes were assessed for both dominant and non-dominant limbs. Significant correlations (r = 0.46–0.60, P
