Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To understand the cardiovascular reactions of the human body to changing conditions of gravity is an important aim of space science. In this context, cardiac output (CO) is a key value to estimate the human cardiovascular system.

The main objective of this experiment is to determine the effects of parabolic flight on intravascular volume, and how these changes modulate the complex haemodynamics induced by the parabolas.
