Prolonged exercise at high ventilatory rates causes airway cooling and drying. Vessel dilation in response to the cooling induces airway edema, and the drying causes osmotic changes and inflammation ...

The fast response of BP and HR to acute stimuli is under autonomic nervous control and thus measurements of the BP and HR during a postural test can be used as one measure of cardiovascular autonomic ...
