Cardiovascular Fitness



Some exercises help you develop cardiovascular fitness. Cardiovascular fitness is the level of fitness you achieve from doing exercises that make your heart and blood vessels healthy. There are many reasons it is important to develop cardiovascular fitness. Your heart is a muscle. It is formed from threadlike fibers. When you do certain exercises, these threadlike fibers become thicker and stronger.
A strong heart is efficient. A strong heart can push more blood with each heartbeat. Your heart will not have to beat as often to supply your body with the same amount of blood each minute. Your resting heartbeat rate lowers giving your heart more rest between beats.

Having cardiovascular fitness affects blood pressure as well as heartbeat rate. Blood pressure is the pressure that your blood exerts against the walls of your arteries. High blood pressure exerts wear and tear on the arteries. It can damage the tissues in the lining of the arteries. A normal or lower blood pressure causes less wear and tear. Cardiovascular fitness improves health by helping to keep pressure within a normal range.
