Weight Loss in Men in Space

Paul Webb 1

1 Webb Associates, Yellow Springs, Ohio

Similar losses occur during simulated weightlessness; blood normally pooled in dependent parts returns to the circulation, increasing central blood volume and causing excretion of water which is not replaced during flight.
