We need to improve our understating of the suitability and limitations of the marker-based motion analysis technique for estimating knee biomechanics during high-impact motion. Are we able to predict players in risk of future ACL injuries?
The reliability and validity of marker-based 3D motion analysis for high-impact motion:
The objective is to describe movement variability, inter-session repeatability. Furthermore the experimental reliability of the knee joint kinematics and kinetics will be examined. Importantly, also the ranking of athletes based on this measure will be studied, as this can be critical for our ability to predict players in risk of future ACL injuries.
All handball and football players athletes of the elite series in Norway will be invited to participate in this study. The subjects will perform vertical drop jumping and sidestep cutting. Marker-based motion analysis will be utilized to calculate the knee joint kinematics and kinetics.
