Correction of water content and solute concentration in blood during hemoconcentration

Abstract

Eleven, healthy male students were subjected to an exhaustive bicyle ergometer exercise. Many parameters of hemoconcentration were examined in blood and urine samples which were collected before and after exercise. In an exercise lasting approximately 10 min, it was found that serum total protein (STP) would be a suitable parameter that could be used to calculate water content and actual decrease in water volume in blood due to exercise. Further, it is described how STP values before and during hemoconcentration can be used to eliminate the effect of plasma water loss from the determined values of various solute levels in blood.
