What are the changes that take place in cardiovascular system by doing regular exercise?
Answers
the heart rate increases,pumping blood in different directions increases,oxygen consumption is high ,glycogen in liver is converted to glucose etc but main cardiovascular change is increase in heart rate'
Explanation:
It is widely accepted that regular physical activity is beneficial for cardiovascular health. Frequent exercise is robustly associated with a decrease in cardiovascular mortality as well as the risk of developing cardiovascular disease. Physically active individuals have lower blood pressure, higher insulin sensitivity, and a more favorable plasma lipoprotein profile. Animal models of exercise show that repeated physical activity suppresses atherogenesis and increases the availability of vasodilatory mediators such as nitric oxide. Exercise has also been found to have beneficial effects on the heart. Acutely, exercise increases cardiac output and blood pressure, but individuals adapted to exercise show lower resting heart rate and cardiac hypertrophy.
