Abstract
This paper studied the recognition of concussion, which lately has been considered a problem in sports-related head injuries. Participants in a judo leadership training session were surveyed. The result of the survey showed that while most respondents were aware that symptoms such as “impaired consciousness” should be regarded as symptoms of concussion; only half of the respondents knew that symptoms such as “behavioral change” should be regarded as symptoms of concussion. This indicates that it might be possible to overlook concussion or underestimate its symptoms. About half of the respondents said they had experienced the occurrence of concussion on the mat while teaching, and at least 40% of respondents had the judoka resume training without providing sufficient rest. Concussion had long been categorized as a “mild symptom” among head injuries; however, the potential risks associated with concussion have been pointed out in recent years. Therefore, it is important to recognize and understand concussions correctly to ensure the safety of judoka.
