Increased blood pressure Muscles begin to ache
Breathing becomes quicker + faster
Body temperature increases
The effects on the cardiovascular system after regular exercise
Decreased resting heart rate Healthier veins and arteries
Increased Stroke Volume Lower resting pulse + recovery rate
Change in cardiac output
Blood pressure reduces
Cardiac output = stroke volume x heart rate
