As a method of analyzing a technical factor in tennis, many 3-dimensional analysis methods have been used. On the other hand, there is a method using a score sheet as the simple analysis method. However, the score sheet has seldom been prevailing in Japan. The purpose of this research is to check the usefulness of the objective analysis by the score sheet, comparing subjective analysis one. Subjects are 10 college level tennis players of T university. The players of near ranking did the game of a one-set match, and the game was recorded with VTR. Immediately after the game, the player looked back upon the game with the score sheet, and did subjective analysis. After that, the player looked back upon the game recorded with VTR anew, did objective analysis. The shot which analyzed is four, the probability of 1st service, the winner of a forehand, the error of a forehand, and the error of backhand. The main results were as follows : (1) About 30% of fluctuation was found between the objective analysis and subjective analysis. (2) In the probability of the successful 1st service, subjective analysis analyzed it lower than objective analysis. (3) Although the number of the winners to whom he struck the player was memorized, the winner whom the enemy struck tended to have analyzed mostly. (4) About an error, there was a tendency for subjective analysis to exceed objective analysis. From these points, a difference is found between the objective analysis and subjective analysis, and the usefulness of a score sheet was suggested. Moreover, it was suggested to analyse that weak consciousness and the mental influence by the pressure from an enemy are concerned greatly.
