Three-dimensional analysis of wheelchair marathon racing forms was performed using 2
cameras, involving 6 wheelchair racers who participated in the Para-Ekiden Race, representing their prefectures.
Among the racers, marked variations were observed in the hand movement trajectory; the trajectory was elliptic in all cases, but the axis of the ellipse varied, and its angle was strongly correlated with each racer’s recent results.
Further studies may be necessary to clarify whether the hand movement trajectory is associated with the speed of shoulder or elbow movement or racing form.
