The purpose of this study was to examine the change of Self-concept of undergraduates who participated in a camping intensive course. There were 28 subjects of both sexes. For a questionnaire, the self Enhancement Scale created by Kajita was used. The survey was conducted on the undergraduates before and after the camp. As a result, the following findings were obtained: 1) The self-growth points of undergraduates who had participated in the Camping Intensive course increased after the camp. Thus, the Camping Intensive course had helped to improve their self-concept.2) "Effortism," a component of self-concept, increased dramatically after the camp (P<0.05) .3) As a result of a factor analysis of the study results, we were able to sample the four factors of "achievement motivation and self-confidence," "inferiority complex," "effort/challenge," and "other-consciousness." 4) After the camp, we observed a decline in the rank of the "achievement motivation and self-confidence factor" and a rise in the ranks of the "inferiority complex factor" and "effort/challenge factor."

本研究は柔道の衝撃負荷定量化をし科学的エビデンスに基づく安全に柔道を学習するための新資料の提供を目的とした。本研究は柔道初習者が最初に学ぶ受け身に焦点を当てた。なぜなら受け身は学習者が受ける衝撃負荷を全身運動をもとに緩衝する技術であり事故防止には重要な学習項目である。研究を進める中で以下の点があきらかになった①柔道熟練者はどの方向に投げられても採用する受け身は「横(側方)受け身」であった。②「横(側方)受け身」は「後ろ(後方)受け身」と比較して大外刈りを施された際の頭部動揺が小さい傾向があった。③「横(側方)受け身」の頭部動揺が小さい理由は「横(側方)受け身」頭頸部筋力の有効活用があった。
