<![CDATA[This study aims to analyze the effect of High-Intensity Interval Training (HIIT) on the endurance of basketball athletes. Endurance is a crucial physical component in basketball because the game requires repeated high-intensity activities over a long duration. The research method used is an experimental design with a quantitative approach through a pre-test and post-test in a single group. The subjects were basketball athletes who followed a HIIT training program for several weeks. The instrument used to measure endurance was a cardiorespiratory fitness test such as the beep test or multistage fitness test. The results showed a significant improvement in endurance after the implementation of the HIIT program. Therefore, HIIT is proven to be effective in improving the endurance of basketball athletes.]]>
