U.S., April 28 -- ClinicalTrials.gov registry received information related to the study (NCT07551869) titled 'Oxygen as a Metabolic Modulator: Divergent Physiological Adaptations to Hypoxic and Hyperoxic Tabata Training.' on April 05.

Brief Summary: The purpose of this study is to examine how breathing air with different oxygen concentrations (higher or lower than normal) during high-intensity interval training affects:

* Aerobic capacity (VO₂max)

* Ventilatory thresholds

* Blood lactate levels

* Perceived exertion This research aims to better understand how oxygen availability influences physiological adaptations to exercise.

If you agree to participate, you will undergo the following:

Baseline testing:

* Cardiopulmonary exer...
