Your legs do much more than just help you walk—they play a vital role in keeping your heart and circulatory system healthy. In fact, your calf muscles are often referred to as the “second heart” because of their crucial role in supporting cardiovascular function. To understand this better, HT lifestyle spoke with Dr. priya Palimkar, senior consultant cardiologist at Sahyadri Hospitals, Pune, who has over 19 years of experience.
1. The Calf Muscle: More Than Meets the Eye
The calf muscles, located at the back of your lower legs, are composed of the gastrocnemius and soleus muscles. While they are known for enabling walking, running, and jumping, these muscles also act as natural pumps for your circulatory system.
When the calf muscles contract during movement, they help push blood from the legs back up to the heart. This is particularly important because blood in the lower limbs has to work against gravity to return to the heart, making the calf muscles essential for healthy circulation.
2. Why It’s Called the “Second Heart”
Dr. Palimkar explains that the calf muscles earn the nickname “second heart” because of their role in supporting venous return. Without this pumping mechanism, blood could pool in the legs, increasing the risk of swelling, varicose veins, and even blood clots.
Essentially, just as your heart pumps blood throughout the body, your calves provide an extra boost to ensure blood flows efficiently back to the heart—a silent partner in maintaining cardiovascular health.
3. The Importance of Staying Active
Sedentary lifestyles can weaken the calf muscles, slowing circulation and putting extra strain on the heart. Dr. Palimkar emphasizes simple daily activities that keep the “second heart” functioning optimally:
· Walking or light jogging: Stimulates calf contraction and improves circulation.
· Calf raises and stretches: Strengthen the muscles to pump blood more effectively.
· Leg elevation: Helps prevent blood pooling after long periods of sitting.
4. Calf health and Cardiovascular Benefits
Strong, active calf muscles can help:
· Reduce the risk of varicose veins and swelling.
· Support healthy blood pressure by improving circulation.
· Aid in oxygen and nutrient transport to tissues throughout the body.
· Decrease the likelihood of deep vein thrombosis (DVT) during prolonged inactivity.
5. A Reminder from the Cardiologist
Dr. Palimkar concludes that taking care of your calf muscles is a simple yet powerful way to support your heart. Even small steps like a brisk daily walk or regular leg exercises can make a big difference in long-term cardiovascular health.
“Think of your calves as your heart’s silent helpers. Keep them active, and your heart will thank you,” says Dr. priya Palimkar.
