Abstract
This paper reports the support using videos that was provided to the Japanese national badminton team in preparation for the Tokyo 2020 Olympic Games. As with the preparation for the Rio de Janeiro 2016 Games, we have continued to provide coaches and players with match analysis data and match videos of international tournaments. In addition, to help enhance the quality of their training for the Tokyo 2020 Games, we provided them with training videos along with a delay playback video tool for checking their performance during training camps. Match analysis was intended to determine the play tendencies of the opponents of the Japanese players, and to evaluate the performances of Japanese players for further training. To achieve these purposes effectively, we selected a suitable procedure from four options: specific play scene extraction from match videos, scoring analysis, spatial analysis, and temporal analysis. In particular, the use of temporal analysis was expanded to solve the problems of each player and the team as a whole.
