Task Effects of Long Duration Spaceflight on Venous and Arterial Compliance in Astronauts [VASCULAR COMPLIANCE/PLATTS] (Completed)
Last Published:  07/30/21 01:05:34 PM (Central)
Short Title: Vascular Compliance
Responsible HRP Element: Human Health Countermeasures
Collaborating Org(s):
National Space Biomedical Research Institute (NSBRI)
Funding Status: Completed - Task completed and produced a deliverable
Procurement Mechanism(s):


1. Determine whether noninvasive measures of venous and arterial compliance are altered by long-duration spaceflight exposure in ISS astronauts and whether these changes are related to the development of the VIIP Syndrome.

2. Using 14-days of 6° head-down tilt bed rest as a model of spaceflight, evaluate the effect of aging on vascular compliance using a subject population similar to younger (25-35 yrs) and older (45-55 yrs) astronaut cohorts.

3. Determine whether previous spaceflight experience or training in high performance jet aircraft predispose astronauts to lower venous compliance and/or the development of the VIIP syndrome.
