Abstract:
In this paper, PCA is performed on a set of tactical elements calculated by scoring opportunity analysis for the men’s and women’s Japanese Championships 2017, 2022, and 2023 with different rules. Curling is a winter sport called ”chess on ice”. Curling is considered as a system system consisting of multiple elements, which can be divided into three categories: physical, human and tactical. Among these, strategic and tactical factors are considered to be the most important in top-level competition. In addition, in the curling world, some rules are sometimes changed in order to improve players’ skills and tactics. In this study, we analyzed the changes in tactical factors due to the rule changes. As a result, it is considered that the nautical zone rule is not effective in men’s competitions. In the women’s competitions, scoring points by stealing became more important each time the rules were changed.
