The failure to detect a consistent rise in PaCO2 or fall in PaO2 during exercise has led some to question the relevance to exercise of any experiments that artificially induce hypoxia and hypercapnia to stimulate carotid chemoreceptors.
The concept of such an interaction between the cardiac and respiratory systems was raised by Wasserman's group as a potential mechanism for early exercise hyperpnea (43, 45): the process received the name "cardiodynamic reflex" because of its perceived relevance to exercise.
Following sacrifice, mice were weighed and dissected to determine masses of organs that have potential relevance for exercise physiology.
This illustrates the relevance of correlating the exercise stress test results with prognostic indices obtained by VCAP.
Next, he presents a follow-up laboratory exercise, called The Natural History of You, designed to emphasize the relevance of the tree-building exercise for students, and to help them see themselves as biological entities.
It is thought that these physiological and behavioral changes may well be of relevance for the clinical effects of exercise in patients suffering from stress-related mental disorders [7] [9], [16], [17].
