Centre of Mass position for participants on a treadmill

We have collected data for six participants aged from 18 to 55 years, three males and three females. The study followed ethical protocols as per ethics requirements (UNE HE19-239). We have measured the Centre of Mass (COM) for each participant walking and running on the treadmill as follows:<br>* X-axis in the direction of gait progression with positive pointing forward.<br>* Y-axis in the medial-lateral direction with positive pointing to the right.<br>* Z-axis in the vertical direction with positive pointing upward.<br><br>The markers we used were the Left and Right PSIS and ASIS, then we computed the average of all four. The data were collected for different velocities, at 100 frames per second, over 10 seconds, for each velocity, using an 8 camera, Qualisys Motion capture system with the COM reconstructed using a pelvic marker set within Visual3D.<br>une_gait_participant_info.csv provides metadata about each of the anonymised participants.une_gait.csv provides the participants' time and position information for each of the measured speeds.
