<![CDATA[This study aims to examine the effect of the High Intensity Interval Training method on improving the anaerobic endurance of soccer players based on their playing positions: Goalkeeper, Defender, Midfielder, and Striker. The research employed a quasi-experimental method with a one-group pretest-posttest design. The sample consisted of four soccer athletes, each representing a different playing position. The High Intensity Interval Training program was carried out over a period of four weeks with a training frequency of twice per week. Anaerobic endurance was measured using the Running-based Anaerobic Sprint Test (RAST) both before and after the intervention. The data from the pre-test and post-test were analyzed using a paired t-test. Analysis using SPSS version 23 revealed a statistically significant improvement in the anaerobic endurance of the soccer players after participating in the High Intensity Interval Training program, with a significance value of 0.023 (p < 0.05). These findings support the effectiveness of the High Intensity Interval Training method as an efficient physical training approach to enhance the anaerobic component of soccer athletes across various playing positions.]]>
