　This study aimed to clarify the structure of effective shot combinations for the ground stroke in tennis that can be practically applied to improve individual tactics by drawing on the wisdom of elite tennis players. The interview questions considered the following three concepts: shot combinations, tips on shot movements, the perspective of gauging shots that are advantageous in a rally, and consciousness when moving. The survey method employed a semi-structured interview format. The first author conducted the interviews and analyzed and interpreted the content of the responses; the co-authors performed triangulation to increase the objectivity of the interpreted analysis results. The results obtained were as follows:
　1)Outstanding tennis players were divided according to two types of behavioral strategy for ground stroke shot combinations: in one strategy the player acted according to the opponent, and in the other the opposite situation applied.
　2)A determining factor for gaining advantage during a rally (i.e., an aggressive stroke or a defensive stroke) was the approach toward the ball in the preparation phase of the ground stroke.
　3)The course of the ground stroke (straight or cross) was shown to change if the ball was approached and hit in a way that was applicable for either course.
