The Effect of Exercise and Thermal Stress on Plasma Volume,
Abstract
Six male subjects exercised for 50 min at 25% and 55% of their estimated aerobic capacities in environments of 42C db, 35C wb, and 30C db, 24C wb respectively. Alterations in the haematocrit, haemoglobin and plasma protein concentrations, and in the activity of an injected aliquot of isotopically labelled albumin, were each used to calculate the percentage change in plasma volume occurring during exercise and recovery. It is concluded that exercise is associated with an increased translocation of protein, this leading to elevated plasma protein levels during recovery which favour the return of water to the intravascular space. Haemoglobin concentration is considered to be the most reliable measure of plasma volume change during exercise.
