Hydrogen Water may be beneficial for athletes seeking to optimize their workouts in high temperatures

Hydration with electrolyzed hydrogen water (EHW) may reduce energy expenditure during endurance training conducted in high temperatures.

What is the purpose of the study?

The study, conducted in Japan by Ritsumeikan University, aims to investigate the effects of hydrogen-rich water on:

• Energy expenditure during exercise;
• Body fluid balance;
• Endurance during exercise in high temperatures.
• What does the study involve?
• The study involved 12 athletes aged 20, divided into two groups:
• One group drank plain water (control group);
• The other group drank electrolyzed hydrogen-rich water (EHW).

The procedure included: 60 minutes of cycling at 65% of maximum oxygen consumption (V̇O2max); This was followed by an endurance test to exhaustion. The following were measured during the workout:

• Energy expenditure;
• Blood parameters (osmolality, sodium, potassium, lactate, bicarbonate);
• Skin and muscle temperature.
• What do the results show?
• Energy expenditure: Participants who drank hydrogen-rich water had lower energy expenditure (13.2 kcal/min) compared to the control group (13.7 kcal/min).
• Endurance: The time to exhaustion was similar between the two groups, meaning that hydrogen-rich water does not directly increase endurance.

What are the conclusions of the study?

Consumption of electrolyzed hydrogen-rich water during exercise in high temperatures:

• Reduces energy expenditure, making exercise more efficient;
• Does not significantly affect overall endurance.
• Applications for Athletes
• Hydrogen-rich water may be beneficial for athletes seeking to optimize their training in high temperatures by reducing their energy expenditure.
