"THE SPACE ENVIRONMENT CAUSES ACCELERATION OF VASCULAR AGING: ROLES OF HYPOGRAVITY, NUTRITION AND RADIATION" Short title: "VASCULAR AGING" — Vascular Aging
Building on previous work (Vascular, Vascular Echo), this experiment will study the roles of weightlessness, nutrition, physical activity and radiation on the cardiovascular system and the onset of insulin resistance on orbit.  The study will contribute to the development of countermeasures to maintain astronaut health during long space flights and will help improve health and quality of life here on earth.
