Tennis has a peculiar scoring system. The purpose of this study was clarify the importance of counting one game in tennis matches by studying data from actual games, comprising 42 men's singles matches (907 games) during the Kyushu collegiate tennis championships held in 1997 and 1998. The main criterion for the analysis was the relationship between point-winning at each score and game-winning. It was found that (1) the rate of point-winning by game-winning players was 67.0%, and that the rate of point-winning by opponents was 33.0%. The game-winning players obtained 2/3 of all points. Furthermore (2), the rate of point-winning by players with a leading score was comparatively high at the time of either leading, such as in an up count or a down count, as well as when there was a difference in points at game-point. In particular, the rate of point-winning by game-winning players was significantly high on 0-15 and 15-30. (3) At scores of 30-30 and deuce (i.e. even count), the rate of point-winning by game-winning players was significantly high. These scores led an even count to game-point. These scores also showed a high frequency, and were the key to winning the game. These results suggest that scores of 30-30 and deuce are keys to game-winning, when gaining one point can lead to victory.

The purpose of the present study was to elucidate tactical strategies for winning a tennis match. Forty-two men's singles matches in the 1997 and 1998 Kyushu collegiate tennis championships were analyzed. Analytical criteria were the relationship between point-winning at each score and the techniques used. In the present research, techniques were categorized into the following 5 groups: service, return, stroke, offense and defense. The following results were obtained: 1. Stroke was the most frequently utilized technique regardless of point-winning. 2. Return and defense techniques, which are considered “passive” techniques, produced significantly high rates of point-losing. 3. The rate of point-winning by service was low at high rate counts (HRC), but high at low rate counts (LRC). In contrast, the rate of point-losing by service was high at LRC-game-points. The rate of point-winning by service was higher for players leading in score, and was low at important scores. 4. The rate of point-winning by players using the defense technique was high at HRC-opponent's game-points. To win a point using passive techniques is the most important tactic at opponent's game-points. 5. The rate of point-losing during the offense technique was high at LRC-up counts. Offense techniques are effective for winning points; however, they involve a higher risk of losing points. These results indicate that players should analyze the relationship between point-winning and strategies at each score.

本研究は.テニスの電子スコアブックを用いた新しいパフォーマンス評価法の開発を目的とした.2007年度は各種データとゲーム結果との関連を検討した.その結果,プレーの高速化や時間的要素がプレーヤー個人の特徴を示していることを明らかにした.2008年度はスコアブックの機能追加として時間的要素と最終ショットの頻度を出力するプログラムを開発した.これにより,試合修了後即座にパフォーマンスの結果を出力することが可能となった.
