箱根駅伝チームにおける，予選会と本戦直前のモチベーションビデオ視聴効果

抄録

　This study investigated psychological changes caused by watching a motivational video (MV) just before the match in the Hakone Ekiden team.

　Immediately before and after watching the video, the runners took the Japanese Collective Efficacy Questionnaire for Sports (JCEQS), the Psychological Conditioning Inventory for Motivational Video (PCI for MV) test, and the circle commitment scale test, and wrote a response to an open-ended question about their current feelings.

　A paired t-test was performed on the results of the subscale scores and the total scores of each of the JCEQS, the PCI for MV, and the circle commitment scale tests taken before and after the MV viewing.

　In the JCEQS, significant differences were confirmed in mental and physical skills, teamwork, and total scores. Also, in the PCI for MV, significant differences were confirmed in the categories of general vitality, technical efficacy, fighting spirit, and total score. For the circle commitment scale, a significant difference was not confirmed.

　Text mining analysis of the open-ended questionnaire responses revealed that the word “anxiety” was frequently used just before watching the video, but the words “team” and “do your best” were frequently used immediately after watching the video. This suggests that watching the motivational video brought about a positive change to the runners’ mental states.
