How do my heart and lungs become stronger with cardiovascular exercise?
How do my heart and lungs become stronger with cardiovascular exercise?
- Your heart is a muscle. Regular cardiovascular training can increase the size of the chambers of your heart by 40%. This means your heart will increase in total size, which leads to an increase in the size of your arteries. Your left ventricle walls, which pump blood to your body, increase in thickness. This allows your heart to pump more blood with each beat!
- Your lungs look like an upside down tree. Your alveoli are where gas is exchanged during breathing. Oxygen goes from the alveoli into the blood. Carbon dioxide goes from the blood into the alveoli. This happens instantaneously. The ability of oxygen to cross through the alveolar membrane increase with aerobic training.
- With both your lungs and heart working together you will have a greater aerobic capacity. Your heart will give more blood to your lungs, and your alveoli will be working even better to deliver oxygen to that blood and take carbon dioxide away.
