Acute plasma volume expansion may optimize hemodynamics during prolonged exercise in untrained males; extends evidence on volume-thermoregulation dissociation.
Does acute plasma volume expansion alter cardiovascular and thermal function during moderate intensity prolonged exercise in untrained males?
Acute plasma volume expansion improves cardiovascular performance (lower heart rate, higher stroke volume and cardiac output) but does not alter thermoregulatory responses during prolonged exercise in untrained males.
