Question: I am a cardiac doctor, do you recommend hiking? Marina (Bermeo).
Answer: Hiking is a light-moderate intensity exercise recommended in cardiac rehabilitation programs. Walking improves the heart's response to exertion by increasing the size of its chambers and the amount of blood from each beat. It also increases the number and size of blood vessels, making blood flow greater: it maintains muscle activity and facilitates venous return by transporting blood rich in carbon dioxide and poor in oxygen to the heart and lungs.
