Shows acute hmb-fa supplementation increases antioxidant enzyme activities in elite judoka, highlighting implications for muscle damage and oxidative stress.
METHODS: ². CONCLUSION: Acute post-exercise HMB-FA supplementation in elite judo athletes did not significantly influence muscle damage or oxidative stress markers but transiently increased antioxidant enzyme activities (CAT, GPX, and SOD). These findings suggest an enzyme-specific effect and highlight the need for future studies using more precise oxidative-stress markers and cellular assays to better evaluate antioxidant responses; however, these effects should be interpreted with caution due to potential limitations related to assay sensitivity and the timing of measurements.
