Orthostatic intolerance remains a problem upon return to Earth from the microgravity environment of spaceflight. The goal of the proposed research is to further our understanding of the fundamental adaptive homeostatic mechanisms involved in gravity related changes in cardiovascular and postural function. Cardiovascular, cerebrovascular, and postural sensory motor control systems in male and female participants before, during, and after exposure to graded levels of hyper-G are being investigated.
