The “second heart” that beats in your legs: why you should move it more
Your body hides a powerful ally that takes care of your circulation without you even noticing: the soleus muscle, located in your calves. This “second heart” helps pump blood toward your chest, defying gravity. Keeping it active improves cardiovascular health and prevents problems like swelling, varicose veins, and fatigue. And the best part: activating it is easier than you think.
The Soleus Muscle: The Silent Pump of Your Circulation
Although not well known by many, the soleus muscle plays a vital role in the circulatory system. It’s located on the back of the leg, just below the visible calf muscle (the gastrocnemius). Its specialty isn’t jumping or running, but something more discreet but equally crucial: pushing venous blood from the legs back to the heart.
That’s why it’s called the “second heart.” Its action is especially important when we’re standing, as it prevents blood from pooling in the feet. But the problem is that the soleus muscle is only activated when there’s movement. Sitting or remaining still for prolonged periods of time, as is often the case in offices or on long trips, hinders this function and promotes the appearance of varicose veins, tired legs, or even blood clots.
Scientific Evidence: The Study That Revealed the Hidden Power of the Soleus
In 2023, a study published by researchers Monica Almendras and Erik Peper in the journal Biofeedback focused on the soleus’s role in circulatory health. Through measurements of temperature, venous flow, and oxygen levels, they found that simple movements such as elevating the heels or performing “soleus pushes” significantly increased blood return to the heart.
The finding not only reinforces the importance of movement in combating a sedentary lifestyle, but also suggests specific exercises as a preventative strategy. The research showed that activating this “venous pump” reduces symptoms such as heavy legs and swelling and improves overall oxygenation of the body.
These data don’t stop at the laboratory: they are especially useful for people who work seated, older adults, or those suffering from chronic venous insufficiency. The study highlights that strenuous training isn’t required to reap benefits. Small, regular movements are enough to get this auxiliary heart working.
This scientific evidence reinforces what many experts have already recommended: moving frequently isn’t just a healthy lifestyle suggestion, but a concrete physiological need.
