日本スポーツ振興センターの統計資料によると，中学校は他の校種よりも多くの負傷が発生している。本研究では，生徒の「自意識」に着目し，質問紙と負傷による保健室来室回数との比較を通じて，自意識と負傷頻度の関連について検証することを目的とした。その結果，負傷の多い生徒の方が自分の内面への関心が低い傾向にあり，私的自意識の低さが負傷頻度に影響を与えている可能性が示された。

According to the statistics of 'condition of accidental benefits' by Independent Administrative Agency Japan Sport Council, More students' injury under school control in junior high school happens than other kinds of schools. The injury is due to the human and environmental factor. In this study students' self-consciousness in the human factor was focused on. To get the clue for the prevention of students' injury, it was checked how much students pay attention to themselves with a questionnaire. From the result, through the comparison of the number of visiting a nursery room for their injury, the relationship between the frequency of their injury and their self-consciousness was inspected. As a consequence, students who have injury a lot have less concerned to themselves. This indicated the possibility that students' low self-consciousness, especially their personal self-consciousness influenced the frequency of their injury.
