U.S., Oct. 28 -- ClinicalTrials.gov registry received information related to the study (NCT07897357) titled 'Trained vs. Untrained: Lower Extremity Pressure Changes' on Oct. 06.
Brief Summary: Research shows that how well oxygen moves from the lungs into the blood (called lung diffusing capacity) is linked to a person's aerobic fitness and endurance training. People who exercise regularly often have different lung and heart responses than people who do not. The exact reasons for these differences are still unclear.
