The cardiovascular system is comprised of the heart and blood vessels. It also includes arteries, veins, and capillaries. The cardiovascular system helps maintain homeostasis. The blood vessels deliver oxygen and nutrients to all nerves, tissues and organs in the body. If you are suffering from heart or arterial disorders, it will definitely affect the whole body.
We all know how regular exercise prevents weight gain and improves the health. After all, fitness is an essential part of a healthy lifestyle. But how does regular exercise change the body from within? What are the long-term effects of physical fitness on the cardiovascular system? Read on and find out!
Lower Resting Heart Rate
The heart never rests. It beats 24 hours a day, 7 days a week from the minute you were conceived to the time you die. This organ beats 115,200 times in one day. It’s a strong muscle but only if you keep it that way. Lack of exercise, unhealthy diet and vices could break down the heart. Regular exercise keeps the heart strong so it does not work harder in circulating the blood. This is called resting heart rate. Physical fitness lowers the resting heart rate by up to two beats per minute. This means, your heart will beat 2,880 less in a day.
Improved Blood Volume
Exercising increases the stroke volume of the heart. This refers to the amount of blood being pumped by the heart with every beat. Every time your heart beats, blood enters the left ventricle and out the blood vessels. This motion pushes blood into the veins and into your every organ. This is how your tissues get access to oxygen. By exercising, the heart achieves stronger, more powerful muscle contractions. This literally increases the pumping power of your heart. When the stroke volume of the heart is increased, it does not work as hard as it should.
Increases Capillary Density
Capillaries are diminutive blood vessels linked to bigger arteries and veins. They go to organs and other tissues to supply nutrients. Exercising regularly boosts the density of the capillaries. This means the organs and tissues get more nutrients. The organs become even more efficient in eliminating wastes like carbon dioxide with more capillaries. When your body is healthy at a cellular level, you become even stronger.
Boosts Arterial Wall Elasticity
When the arterial wall remains pliant and elastic, it can withstand high blood pressure. Weak arterial wall leads to damaged or ruptured arteries. It could also cause health complications. Exercising helps keep the arterial wall elastic so the body can adapt to changes in pressure more effectively. Physical fitness also allows the heart to supply more oxygen without decreasing the cardiac output in high pressure.
Faster Recovery Time
When the heart is strong, you recover faster from any injury or health problems. If you’ve been exercising for years, your blood pressure remains normal. Sure, pressure will spike as you work out but it will go back to normal at a much faster speed. This is an indication of good health and efficient cardiovascular system.
