Drinking Effect of Electrolyzed Alkaline Reduced Water on Oxidative Stress and Fatigue After Intense Exercise

The goal of this clinical trial is to test the drinking effect of electolyzed alkaline reduced water (ARW) generated from alkaline ionizer (CGM MWPI-2101) on oxidative stress and fatigue after high-intensity exercise in healthy people. The main question\[s\] it aims to answer are: * \[question 1\] Can pH 9.5 EARW reduce oxidative stress compared to purified water (PW) * \[question 2\] Can pH 9.5 EARW decrease fatigue markers in blood Participants will drink water from the experimental device after high-intensity exercise. Blood sample will be collected before exercise, after highly intensive exercise, and after then 15 min. of drinking water. Researchers will compare EARW group and PW group to see the anti-oxidative and anti-fatigue effects.
