As Para-badminton was adopted as an official event at the Tokyo 2020 Paralympic Games. However, little research and development of badminton wheelchairs in Japan has been conducted. In this study, we focused on the chairwork movement, which is the important technique in wheelchair sports and evaluated that of the wheelchair badminton. Furthermore, we clarified the movement characteristics of the chairwork in wheelchair badminton and to obtain knowledge for new wheelchair development. In this study, the new and old of 2 type wheelchairs were used. New type was made by Mg base alloy material and old one was made by Al base alloy material. First of all, the subject got on the new type wheelchair and stooped after driving 1 drive forward from the end of the court and then stopped after driving 1 drive backward. Five sets of this series of operations were measured. After that, we exchanged to an old type wheelchair and measured 5 sets in the same way. The above operation was measured by recording the locus of the reflective marker using eight infrared cameras. As a result, wheelchair that maintains the speed after driving because the speed of the new model is the same as the old model or higher than that of the old model. It was confirmed that there was. As a feature of the operation, it was confirmed that there was a difference in tendency between the forward movement and the backward movement based on the displacement of the wheelchair speed.
