Effect of Pre-exercise Inhalation of Molecular Hydrogen on Metabolic Response During Graded Exercise in Healthy Women
Effect of Repeated Pre-exercise Inhalation of Molecular Hydrogen on Metabolic Response During Graded Exercise in Healthy Women: A Randomized, Double-blind, Placebo-controlled Crossover Trial
The goal of this clinical trial is to evaluate if molecular hydrogen can reduce the metabolic response during graded exercise in healthy women aged 18-30 years. The main questions it aims to answer are:
- Does molecular hydrogen reduce the respiratory exchange ratio?
- Does molecular hydrogen reduce oxygen uptake?
Researchers will compare molecular hydrogen to a placebo (ambient air containing no molecular hydrogen) to see if molecular hydrogen reduces the metabolic response.
Participants will:
- Inhale molecular hydrogen for 60 minutes each day for 7 days.
- Undergo an exercise testing twice after a two-week washout period.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Respiratory exchange ratio
Lasso di tempo: Change after 2 weeks of crossover.
|
Respiratory exchange ratio is measured using an Ergostik analyser (Geratherm Respiratory, Bad Kissinger, Germany) breath by breath during the exercise, and the average is calculated for 6-minute segments for subsequent analysis.
|
Change after 2 weeks of crossover.
|
Misure di risultato secondarie

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Oxygen uptake
Lasso di tempo: Change after 2 weeks of crossover.
|
Oxygen uptake is measured using an Ergostik analyser (Geratherm Respiratory, Bad Kissinger, Germany) breath by breath during the exercise, and the average is calculated for 6-minute segments for subsequent analysis.
|
Change after 2 weeks of crossover.
|
|
Carbon dioxide production
Lasso di tempo: Change after 2 weeks of crossover.
|
Carbon dioxide production is measured using an Ergostik analyser (Geratherm Respiratory, Bad Kissinger, Germany) breath by breath during the exercise, and the average is calculated for 6-minute segments for subsequent analysis.
|
Change after 2 weeks of crossover.
|
|
Minute ventilation
Lasso di tempo: Change after 2 weeks of crossover.
|
Minute ventilation is measured using an Ergostik analyser (Geratherm Respiratory, Bad Kissinger, Germany) breath by breath during the exercise, and the average is calculated for 6-minute segments for subsequent analysis.
|
Change after 2 weeks of crossover.
|
|
Breathing frequency
Lasso di tempo: Change after 2 weeks of crossover.
|
Breathing frequency is measured using an Ergostik analyser (Geratherm Respiratory, Bad Kissinger, Germany) breath by breath during the exercise, and the average is calculated for 6-minute segments for subsequent analysis.
|
Change after 2 weeks of crossover.
|
|
Heart rate
Lasso di tempo: Change after 2 weeks of crossover.
|
Heart rate is continuously recorded during the exercise using a Polar H10 chest strap (Polar, Kempele, Finland), and the average is calculated for 6-minute segments for subsequent analysis.
|
Change after 2 weeks of crossover.
|
|
Blood lactate concentration
Lasso di tempo: Change after 2 weeks of crossover.
|
Capillary blood lactate concentration is assessed at baseline (resting condition) and during the final minute of each exercise step using a Lactate Scout device (EKF Diagnostics, Barleben, Germany).
|
Change after 2 weeks of crossover.
|
|
Rating of perceived exertion
Lasso di tempo: Change after 2 weeks of crossover.
|
Participants are asked to subjectively rate their perceived exertion at specified time points - at rest and subsequently in the last minute of each exercise step.
The Borg's scale 6-20 is used, where 6 means "no exertion" and 20 means "maximal exertion".
|
Change after 2 weeks of crossover.
