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.
