The effects on the cardiovascular system during exercise
Increased heart rate Start to sweat
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
Blood ejected from the The volume of blood pumped
heart per min out the heart by each ventricle
during one contraction…read more
