Abstract
To effectively promote training, it is first necessary to explicitly define the structure of the target sports performance, namely, a structural model as a blueprint (JSPO, 2019). The performance in measurable events such as jumping events and sprinting in the track and field can be relatively structured owing to clear indicators such as jump distances and running times. However, in ball sports, it is necessary to capture the performance structure in a hierarchical manner, including tactics, techniques, and physical fitness, and to explain performance using more abstract concepts. In this paper, the author, who holds a higher-level certified sports instructor qualification, attempts to structure game performance in tennis and presents it as an idea. The abstract elements, such as the purpose and structure of tennis, and specific game techniques, such as strategies and tactics, as well as the detailed techniques to achieve those strategies and tactics–in other words, the technical structure of each shot– were outlined, along with their connections and elements. The visualized game performance structure of tennis created by the author could become an important tool for deepening the mutual understanding between players and coaches.
