Equestrian riding involves three-gaits. The purpose was to objectively validate the accuracy of Actigraph-GT9X for the equine step-counts. One-minute interval data for each gait (walk, trot, and canter) while lunging the horse and riding was collected. Visually counted (N=1) pilot-study indicates the current step counting technology seem to be inaccurate for canter, and rider measurements are not a reliable indicator for horse-steps. Future work will investigate alternative methods to accurately identify equestrian gait and step-counts.
