Thermal fluid analysis in a wheelchair marathon

Abstract

In the running attitude considered to be greatly related to the recording in the wheelchair marathon, it varies depending on the players, and there are not many researches on air resistance due to this difference in posture. Reduction in air resistance during driving also leads to a reduction in physical strength consumption of competitors. On the other hand, disabled people are considered to be a social problem that the risk to the body during competition is very large unlike healthy subjects. In particular, many of the athletes suffering from spinal cord injury are presumed to be difficult due to autonomic dysfunction, various disorders such as perspiration disorder and temperature control dysfunction are caused, and physical condition control during competition becomes difficult. Therefore, in this study, we aimed to visualize the optimal running attitude with less air resistance and the flow of heat around the athlete model using numerical fluid dynamics analysis and consider the running attitude and the heat around the athlete.
