The Effects of Astaxanthin on Physiological Anti-fatigue and Sports Performance: an Integrated Study From the Application of Laboratory Human Sports Platform to Simulated Competitions

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.

Inclusion Criteria: * A minimum of five years of badminton training experience (with a training frequency of at least three times per week, sustained for three consecutive years). Exclusion Criteria: * chronic diseases, such as heart disease or hypertension, drinking habits and severe lower limb musculoskeletal injuries within the past six months.
