Capturing in Season Change-of-Direction Movement Pattern Change in Youth Soccer Players with Inertial Measurement Units

This study aimed to examine the utility of inertial measurement unit (IMU) technology identify angle, step-specific, and side-specific differences between youth soccer players with without a history lower limb injury during soccer-specific field tests. Thirty-two youths (mean age 16.4 years) who were elite (Females n = 13, Males 19) wore IMUs pre- postseason change-of-direction assessments. A response feature analysis was used compare change in peak resultant acceleration groups at level significance p < 0.05. Statistical revealed significant right leg final foot contact 180° pivot turn (p 0.012, ES 1.0) 90° cut 0.04, 0.75) two groups. These data suggest that might experience greater angle within season when compared injury-free athletes. demonstrates may present useful method analyze players’ direction movement after returning play. results can inform future studies investigating player monitoring prove be tool for coaches designing individualized training programs this population.
