 note = {This study aimed to understand how the changes in the number of competitions that included triple-jump events for female senior-high-school students have affected the domestic competition level. Records of senior-high-school girls’ Top 100 Rankings in triple jump in Japan in 2000–2019 academic years were collected, with similar data on long-jump and high-jump events. Furthermore, data were collected on whether senior-high-school girls’ triple jump was included in national-level outdoor athletic competitions each year to examine how this finding was related to the competition level. The primary results were as follow: (1) the highest level of domestic competition was held in the 2017 academic year, which was the first year when
triple jump was officially adopted as an event in the All-Japan Inter-High-School Championships and when senior-high-school girls’ triple jump was included in the most number of competitions. This finding indicates that the change in opportunities to include senior-highschool girls’ triple jump events in the national-level competitions may affect the domestic competition level. (2) The results indicated that after the girls’ triple jump was first included in the Under-18 Japan Championships in Athletics in the 2008 academic year, triple jump gained popularity among first- and second-year senior high school girls. The results suggested the possibility that this event led to a gradual increase in the domestic competition level up to the 2017 academic year, when triple jump was first included in the All-Japan Inter-High School Championships. (3) Years when a high-level domestic competition exhibited numerous athletes
contributed to the rankings for the two events of triple jump and long jump, and this trend was particularly apparent until the 2008 academic year, thereby indicating the possibility that the domestic competition level increased because of athletes specializing in long-jump training to enter the triple jump event in the National Sports Festival of Japan.},
