To address the rapid recovery needs in intensive badminton competitions, this 2-year study evaluates Astaxanthin (AST) as a potential ergogenic aid. The research aims to elucidate how AST attenuates exercise-induced oxidative stress, inflammation, and muscle damage. By establishing an evidence-based nutritional strategy, this study seeks to maintain peak performance for elite athletes in badminton and other racket sports, while supporting the development of functional anti-fatigue health products.
