Anatomy and physiology Task 3 Consistent aerobic exercise has many physiological effects on the cardiorespiratory system. The heart like any other muscle needs exercise, this exercise comes in the form of aerobic exercise. In this assignment I am going to illustrate the changes that occur in certain areas of the cardiorespiratory system when aerobic exercise is undertaken:> Stroke volume> Heart rate (pulse and rhythm strip)> Cardiac output> Blood flow> Myocardium> Fatty deposits> Capillarisation Stroke volume As a result of aerobic exercise the S.V. shows an overall increase. S.V. at rest is substantially higher after an endurance training programme than it is before training. The graph above shows the changes in stroke volume of a subject before and after a six-month endurance-training programme. After training the left ventricle fills more completely during diastole than it does in an untrained heart, this happens because of an increase in the blood plasma volume, which in turn means more...
