ウィルチェアーラグビー競技時の転倒と防御動作に関する研究

抄録

The prevention of injuries during parasports is important for safety and to enjoy sports. However, in wheelchair rugby, there are few systematic studies on trauma precautions because of the differences in the physical function level of parasports athletes and the small number of players overall. We have proposed defensive motions to minimize injuries to the front and sides by analyzing videos of falls, a simulation using a multi-body model, and evaluating the injury to the head and upper limbs. By classifying the range of motion and muscular strength into three categories, the difference in disabilities was expressed using a multi-body model. The index, ULIC, was proposed to evaluate injuries to the upper limbs. It is calculated from the maximum moment value of the bones, using a simplified cylindrical model. The head injury criteria (HIC) and ULIC made it possible to evaluate the extent of injury by classification into one of four categories, depending on the presence or absence of injuries in the above regions. Furthermore, defensive actions not resulting in serious injuries and matching the difference between the degree of disability and fall, by predicting the potential injury to the head and upper limbs using the indexes, were proposed.
