Acute Responses to Exercise: Summary ResponseDefinitionType of ResponseEffect of ExerciseThe benefit of this response / why it happensHow it occursVentilationThe amount of air breathed in and out per minute. The product of Tidal Volume (TV) x Respiratory Rate (RR)RespiratoryIncreasesTo increase the volume of oxygen in the lungs that can be diffused into the blood and transported to the working musclesGreater contraction of the intercostal muscles and diaphragmDiffusionThe movement of oxygen and carbon dioxide from an area of high concentration to an area of low concentration. Occurs in the alveoli of the lungs and the muscle capillaries.Respiratoryand CirculatoryIncreased CapacityIn order to increase the transfer or oxygen into the blood stream and delivery to the muscle cells. Also, to dispose of carbon dioxide which is produced as a result of the aerobic energy systemCaused by an increased surface area of the alveoli and muscle tissueCardiac Output (Q)The product of Stroke Volume (SV) x heart rate (HR). The amount of blood pumped out of the left ventricle per
