CroatiaThe article explains how the muscles in the calves act as a secondary heart, aiding blood circulation by pumping blood back towards the heart against gravity. It describes the mechanism through which these muscles contract to push blood through veins, assisted by one-way valves. The piece highlights research linking reduced calf muscle pump function to increased mortality risk, citing two studies, one from 2020 involving 2,728 adults and another from 2024 with nearly 6,000 participants. Both studies showed a correlation between weaker calf pumps and higher mortality rates over time. However, the studies were observational and did not prove causation. The article concludes with simple ways to activate the calf pump, such as walking, running, climbing stairs, and repeatedly standing on toes. It advises office workers to avoid prolonged sitting and recommends moving regularly.
Bias read (Center): The article presents scientific information about the physiological role of calf muscles in circulation and their health implications. It cites multiple studies but does not take a partisan stance. The tone remains neutral, focusing on factual explanations and medical findings rather than advocacy.
