iss038e055233 (2/24/2014) --- Cosmonaut Oleg Kotov, Expedition 38 Commander, is seen during a Lower Body Negative Pressure (LBNP) exercise. This activity was performed for the DAN investigation where researchers revealed that crew members inadvertently hold their breath longer in microgravity than on the ground, especially if the crewmember is lying face up. A better understanding of the supply of oxygen to the body in microgravity allows researchers to provide the environment necessary for adequate intracellular functions and basic human health in space.
