cardiovascular adaptations

Cardiovascular adaptations refer to changes in your heart and blood vessels in response to regular exercise. These changes improve how efficiently blood is pumped and oxygenated throughout your body. For example, the heart may become stronger and more efficient, allowing it to pump more blood with each beat. Blood vessels can also become more flexible and numerous, helping blood flow more easily. These adaptations enhance endurance, reduce fatigue, and lower the risk of heart-related diseases by supporting better circulation and oxygen delivery to tissues.
