REDUCED 3D MARKER SET TRACKING OF ELITE SPRINT TRAINING

Abstract

The purpose of this study was to develop a system to measure step length, step frequency and step velocity variations in elite athlete sprint running. Three CODA CX1 scanners were sited parallel to an indoor running track to record markers on each foot of an elite 400 m athlete sprinting in a straight line and around Lane 1 of a banked track. The goals were to produce a system which could be used routinely in training and would be accurate enough to detect small changes in step kinematics to enable variability in constant speed sprinting to be studied. The system developed was able to produce the desired data, was convenient and could be applied equally to straight and bend running.
