3. Introduction Multiple cardiovascular adaptations occur in response to exercise training, including changes in the following: Heart size Stroke volume Heart rate Cardiac output Blood flow Blood pressure Blood volume Picture Credit: P hysiology of Sport and Exercise, 3rd edition. (Wilmore JH, Costill DL)

4. Cardiac output Cardiac Output = Stroke Volume * Heart Rate While stroke volume increases, heart rate generally decreases at rest and during exercise at a given absolute intensity Cardiac output at rest and during submaximal exercise at a given exercise intensity does not change Maximal cardiac output, Increases with the aerobic activity .

5. Blood Flow Increased capillarization Greater recruitment of existing capillaries More effective blood flow redistribution from inactive regions Increased total blood volume Picture Credit: P hysiology of Sport and Exercise, 3rd edition. (Wilmore JH, Costill DL)
