[Effect of a combination of head-down posture and LBNP on human tracking performance and spatial orientation].
Test subjects exposed to a head-down tilt at--30 degrees for an hour participated in the experiment. The use of LBNP during tilting improved precision of arrow orientation on the round-shaped screen (during continuous tracking) but did not influence orientation relative to the gravitational axis and the long axis of the body. The selective effect of LBNP on the orientation can be attributed to the increased importance of inner coordinates due to the pressure of interior walls of the LBNP suit on the foot surface, and blood pooling in the dependent part of the body.
