Abstract
The body’s response to an exertional stimulus, if performed adequately to meet the imposed demand, is an orchestrated response predominantly among the cardiovascular, pulmonary, and skeletal systems. These physiological systems work together to ensure that up-titrated energy and force production demands are met. The magnitude of the exertional stimulus these systems are able to respond to, when an individual is in a true state of physiological health, is influenced by multiple factors including age, sex, biomechanics, genomics, and exercise training history. When one or more of these systems suffers from dysfunction, as is the case when an individual is at risk for (i.e. unhealthy lifestyle history) or diagnosed with a chronic disease, the response to a physical stimulus ultimately fails and exertional capacity is limited. There is a clear and well-established clinical relevance to the cardiovascular response to an exertional stimulus, commonly assessed through a graded aerobic exercise test on a treadmill or cycle ergometer. In fact, aerobic capacity has been referred to a key vital sign. We are also gaining an appreciation of how communication and presentation of information between health professionals and individuals receiving care significantly impacts comprehension and adherence to a plan of care. This chapter addresses these areas, beginning with a brief granular description of exertional cardiovascular physiology, transitioning to practical clinical implications of this information for health professionals, and ending with how the individuals seeking healthcare receive, process, and comprehend this information with the ultimate goal being real-world application and improved health outcomes.
