Description
The aim of this study was to investigate the longitudinal relationship between performance improvement and changes in run-up speed, jumping distance, and jumping ratio of each phase in a case study of female triple jump athletes who broke the Japanese national record. The subject was one female triple jumper who achieved the Japanese national record in the triple jump (14.16 m) and participated in the World Championships in the year 2023. The run-up speed and jumping distances of each phase were measured using a laser distance measurement device (LAVEG) and a high-speed camera. The subject in this study improved her personal record in the triple jump from 12.91 m to 14.16 m during the research period (2016-2023). The subject improved her triple jump performance by increasing the jumping distance of the hop and step phases from 2017 to 2020 without improving maximum run-up speed. In the years 2021 and 2022, she maintained her maximum run-up speed and decreased her jumping distance of the hop phase. However, her performance was improved by increasing the jumping distance of the jump phase from 2021 to 2022. In the year 2023, her performance was improved by increasing the maximum run-up speed and by maintaining the jumping distance of the jump phase while increasing the jumping distance of the hop and step phases.
