The Surprising Connection Between Your Calves and Heart Health

Your coronary heart is the fist-size muscular middle of your cardiovascular system. Some 100,000 occasions a day, it pumps about 10 pints of oxygenated blood out of your lungs out by way of 60,000 miles of veins and capillaries to your farthest extremities.

However your coronary heart will get assist from an surprising supply, in response to the most recent considering from cardiovascular consultants. You’ve a “second coronary heart” that performs a vital function in your physique’s circulatory system — your calf muscle tissue.

“One coronary heart pump has sufficient energy to ship blood to each a part of the physique, reaching your decrease legs in seconds,” writes phlebologist Sonja Stiller, MD, in a weblog for the Heart for Superior Vein Care in Mentor, Ohio. “As soon as the blood has reached each a part of the physique, the veins have to hold the oxygen-depleted blood again to the center and thru the lungs, the place it is going to obtain a provide of oxygen. Nonetheless, because the blood is flowing in opposition to gravity, sending it towards the center will take greater than a single pump from the center. Because of this, the physique makes use of the calf muscle tissue to pump blood out of your decrease legs again to the center.”

“The physique makes use of the calf muscle tissue to pump blood out of your decrease legs again to the center.”

Different leg muscle tissue and your ft additionally play a job, however the calves are particular, each due to sure properties and their place within the physique. Inside their system of muscle tissue and veins, calves characteristic valves that act as trapdoors, opening and shutting with every muscle contraction to forestall a backflow of blood.

“The veins in your calf act like a reservoir for blood [that] your physique doesn’t want in circulation at any given time. . . . When the calf muscle contracts, blood is squeezed out of the veins and pushed alongside the venous system,” notes Louis Prevosti, MD, of the Heart for Vein Restoration in Atlanta. “One-way valves within the leg veins maintain the blood flowing within the appropriate course towards the center. These valves additionally stop gravity from pulling blood again down your leg veins within the fallacious course.”

The Position of Motion

Train is important to cardiovascular — and general — well-being. It enhances the well being of veins and muscle tissue; prompts the discharge of chemical messengers, often called myokines, that support cardiovascular perform and battle irritation; and helps mitochondria, the mobile energy vegetation in our our bodies that create power.

Understanding the calves’ half within the cardiovascular system makes the function of motion all of the extra clear. “One of the best ways to enhance circulation is to get transferring. Each time the calf muscle tissue contract, it helps blood to move in opposition to gravity,” Stiller explains. “If you happen to don’t transfer for lengthy durations, blood and toxins will gather in your decrease legs and trigger swelling.”

Sitting or mendacity down permits blood and lymph to pool within the calves, placing stress in your coronary heart.

There are a number of simple methods to spice up each of your hearts.

  • Take a stroll. Motion doesn’t must be an all-out dash to be useful. “Even one thing as easy as taking a stroll or doing rigorous family chores does a great job of getting the blood transferring,” says Christopher S. Baird, PhD, affiliate professor of physics at West Texas A&M College. “You shouldn’t have to stroll for a very long time or stroll rigorously to get your blood transferring. That is totally different from train that’s supposed to construct muscle and cardiovascular power, which wants to be longer and extra intense to do its job.”
  • Schedule motion breaks. “When sitting, stand up each 20 minutes and simply transfer,” advises Erik Peper, PhD, a professor on the Institute for Holistic Well being Research at San Francisco State College. (See our One Wholesome Behavior Problem for inspiration and concepts to get extra motion into your day.)

“If it’s a must to take an extended flight, it’s a good suggestion to stand up each hour or two and stroll up and down the aisle somewhat,” says Baird.
