Description

In this study, we will clearly quantify the appearance frequency of shots selected and executed by players during the play of the official game, and examine the relationship between the appearance frequency of shots and performance considering the difference due to gains and losses and the flow of the game. Therefore, the purpose was to use it as a material for obtaining strengthening guidance measures for the athlete in the future. The subjects were one college tennis player (player A, male, Intercollegiate Qualifying level). Furthermore, one player (player B, male, Intercollegiate Main draw level) of the opponent was compared. The research method was to shoot a video of the actual official game and analyze the contents of all points and all shots together with the performance. For player A, we analyzed the winning and losing factors of the match, considering the degree of confidence in each shot given in advance and the rating score that evaluates the technique of each shot. The results suggested the following. 1) Difference due to gain / loss points Regarding the forehand, which is the specialty of player A, the frequency of appearance of forehands including cross-1 and straight-2 was very high at 31% of the total, and it was found that self-confidence and skill were related to the frequency of appearance. However, at the time of conceding, Cross-1 made 5 out of 13 mistakes (38.4% error), and Straight-2 made 3 out of 9 mistakes (33.3% error). It can be seen that he made a mistake and accumulated goals. 2) Frequency and performance of shots considering the flow of the game The game was divided into three parts, the beginning, the middle, and the end, depending on the game development. Player A had no mistakes in the forehand cross-1 that he was good at in the early stages, and in the middle stage he increased the number of strokes and made few overall mistakes, and was able to proceed predominantly. However, at the end of the game, player B deployed Cross-1 to straight -2 and hit the back, which made more mistakes and led to more goals.
