Fig. 3From: Concurrent validity of lower extremity kinematics and jump characteristics captured in pre-school children by a markerless 3D motion capture systemMeasures of Knee Flexion, Knee Hip Separation Distance Ratio, and Knee Varus throughout a standing broad jump.The Grey vertical lines represent the moments of toe off and landing. A clear movement artifact is seen in the Vicon measures of Knee Varus. This artifact is believed to be caused by “wobbling” of the thigh wands in response to the rapid movements performed by the subject when setting off and landingBack to article page
