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

Not Applicable

Completed

• Conditions: Oxidative Stress

• Registration Number: NCT05673395
• Lead Sponsor: Kyu Jae Lee

Brief Summary

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.

Detailed Description

This study was designed as a randomized, controlled, crossover, double-blind clinical trial with a single intervention of ARW intake (pH 9.5, 10 mL/kg body weight) after highly intense exercise.

The participants were divided into two groups, wherein they consumed either purified water (PW group) or EARW (EARW group). Blood samples were collected before exercise, immediately after exercise, and 15 min after drinking water.

For the anti-oxidative effect, ROS, NO, GPx, and MDA levels were measured. For the anti-fatigue effect, latate, lactate dehydrogenase, phosphate and calcium were measured.
