Calves are Vascular Pumps to Help Blood Flow Back to the Heart
The blood sent from the heart transports nutrients and oxygen through the blood vessels to the microvasculature throughout the body. During the process, a portion of the blood leaks out of the blood vessels to replenish nutrients for the cells of the subcutaneous tissues and to absorb the waste materials and carbon dioxide, and it then reenters the blood vessels and flows back to the heart. This process takes about 60 seconds, and this cycle will continue as long as the person is alive.The blood vessels that transport blood from the heart are arteries, and the vessels that return blood to the heart are veins.
The arteries use the heart as a pump, supplying blood at a fixed speed, and the blood flows together to the extremities of the body.
The arteries don’t have to work on their own, as the heart is a pump that helps send blood throughout the body.
So, what is the pump that helps the blood flow from the veins back to the heart? It is the calf muscles.
When the calf muscles are tightened, they will compress the veins that return the blood to the heart from the muscles. You can think of this process as pressing the pump with both hands when filling the tires of a bicycle with air. When standing, the blood in the veins will flow from the bottom to the top, and there are valves inside the veins to prevent backflow.
In modern times, many people don’t have a large physical workload, so they must use some methods to promote the operation of the venous valves to maintain balance.
Three Types of Massage to Promote Blood Circulation
1. Massaging the calf musclesCarefully massage the muscles from the Achilles tendon to the kneepit.
There’s no need to exert a lot of force. Please use a comfortable amount of force to massage the muscles. Massage each leg for about two minutes, and you can do this during breaks at work.
It is recommended to do this massage after bathing or before going to bed. Please massage both feet separately.
With the soles of your feet facing you, divide them into two parts as shown in the picture.
Slowly push towards the middle and then slowly release.
Repeat about 30 times, and the blood circulation in the veins will be improved, and the feet will become warm.
When the soles of the feet become hard and hot to the point of wanting to apply ice, the situation is quite serious. At this time, please first buy a commercially available foot massage wand.
(1) First, carefully massage the reflex areas for the kidneys, located in the center of the soles, with the massage wand, then roll the wand in the direction of the arrows in the picture towards the inner ankle bone.
(2) Carefully massage the areas that feel uncomfortable or hot.
(3) Repeat steps (1) and (2) to improve blood circulation.
- Carefully massage the center of the sole with a massage wand
- Roll the wand in the direction of the arrows towards the inner ankle bone
We Should Walk a Lot to Exercise Our Calves for Smooth Flow of Body Fluids
Although we know that “the calves are the pumps to help the blood flow back to the heart,” I think most of us have the experience of having our feet become heavy and swollen after sitting for two hours at a meeting. This is because we kept the same posture for a long time, without using our calves.However, we cannot suddenly stand up or walk around in the office...
The key in exercising the toes is to make large movements and move them slowly.
Walking for five to ten minutes during the day will help the venous blood return to the heart.
