<![CDATA[This research examines how knowledge sharing and self-efficacy affect Indonesian elite taekwondo players. Based on the importance of knowledge management and psychological preparation in competitive sports and Indonesian taekwondo players' inconsistent international performance, this study fills a gap in the literature.

Sports stakeholders must emphasize psychologically informed training to generate high-performing athletes, according to the research.]]>
