Exercise Induced Plasma Volume Expansion Lowers Cardiovascular Strain

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.
