Comparison of kinematics and dynamics estimation of lower extremity in basketball players running up and down using markerless and marker-based motion capture systems

Background: Traditional marker-based motion capture systems (MB systems) have been widely validated for their reliability in capturing kinematic and kinetic data by placing markers on athletes. However, the application of markerless motion capture systems (ML systems) in sports scenarios requires further validation, particularly in high-speed and highly dynamic movements such as basketball players' approach and touch high jumps.
