Exercise Induced Plasma Volume Expansion Lowers Cardiovascular Strain and Improves Cycling Time-trial Performance in Acute Normobaric Hypoxia
In Brief
A clinical study evaluating High Intensity Intervals and Moderate Exercise for Cardiac Output and Stroke Volume. Completed, enrolled 8 participants across 1 site.
Detailed Summary
The goal of this observational study was to better understand the impact of increased plasma volume on later exercise in hypoxia. Investigators examined young, healthy, males who regularly participated in aerobic exercise. Investigators first measured participant's response to exercise in hypoxia (simulated \~7,500 feet above sea level). The investigators then had participants either 1) undergo 1 bout of high intensity interval exercise or 2) undergo 1 bout of moderate, continuous exercise. 48 hours after the exercise, participants were again examined in hypoxia.
