Analysis of Differences in Movement and Exercise Intensity of Junior Female Field Hockey Players Using GPS

Abstract

[Purpose] This study aims to analyze the characteristics of exercise intensity according to three positions (Forwards, Midfielder, Defender) for junior female field hockey players utilizing GPS. [Methods] The research analyzed a total of 8 matches played in preparation for the 2023 Asian Junior World Cup, with 19 junior female field hockey players participating. The variables studied were total distance covered (TD, unit: m), low-intensity distance covered (LID, 0-10.9km/h), moderate-(MID, 11-15.9km/h) and high-intensity distance covered (HID, 16km/h), sprint distance (20km/h)and efforts (unit: bouts), and acceleration and deceleration efforts (unit: bouts). One-way analysis of variance was used to validate statistically significant differences in movement by position and exercise intensity. [Results] The study found that, in terms of LID, defenders moved the most compared to forwards and midfielders. However, no significant differences in position were noted for MID, HID, sprint distances, sprint efforts, acceleration and deceleration efforts. [Conclusion] Although these results differ from previous studies, it
