Abstract

Eight female soccer athletes performed six horizontal jump and cut maneuvers onto two AMTI force platforms. 3D kinematic analysis of 22 marked body landmarks coupled with ground reaction forces (GRF) were analyzed for peak knee flexion and valgus angles, GRF, and knee abduction moments with repeated measures ANOVA. Analysis indicated no significant difference between trials (p > 0.05). Average measures Intraclass Correlation Coefficients resulted in values of r = 0.71 to 0.99. Results indicate good reliability for flexion angles and excellent reliability for valgus angles, GRF, and knee abduction moments.
