ブラインドサッカー競技における移動を伴う自己位置の相対的定位に関する研究

抄録

In blind football, players compete without visual information, making movement accuracy based on their sense of proprioception crucial. During matches, players rely on auditory information to perceive their surroundings and move accordingly. While research has been conducted on the sound localization abilities of blind football players, little research has been done on their movement. This study focuses on movement accuracy. The participants were asked to identify the space they should move to based on auditory information, and then they physically moved towards that space. The movement accuracy was compared between conditions with and without a sound source, evaluating the impact of sound presence on the players' movement. The results showed that, compared to novices, experienced players had higher movement accuracy when sound was present. A comparison between the sound and no-sound conditions revealed that experienced sighted players had significantly higher movement accuracy when sound was present compared to when it was absent. On the other hand, for experienced visually impaired players, no significant effect of sound presence or absence on movement accuracy was observed. In the future, we hope to deepen the understanding of the movement mechanisms of visually impaired individuals and provide valuable insights that contribute not only to blind football but also to the field of rehabilitation.
