A recent scientific study has revealed that excessive and prolonged intense exercise may damage red blood cells and cause signs similar to premature aging in them.
Running is considered one of the most extensively researched physical activities worldwide. According to experts, running at a moderate pace for about 150 minutes per week helps improve heart health, enhance blood circulation, and improve overall longevity.
However, a recent study found that extreme long-distance running, such as a 25 mile race or a 106 mile ultramarathon, may cause the breakdown of red blood cells, increasing the risk of anemia, although the long term effects are not yet fully clear.
During the study, blood samples were collected from 23 athletes before and after the race. Researchers analyzed thousands of proteins, lipids, metabolites, and other components in the blood plasma and red blood cells. The results showed that after both races, the athletes’ red blood cells became less flexible and exhibited noticeable signs of aging.
According to scientists, this damage may be linked to changes in blood pressure, oxidative stress, and inflammation.
The author of the study said that these findings indicate that extreme endurance exercise may push red blood cells toward accelerated aging, similar to the process observed during blood storage.
Experts say that moderate exercise is highly beneficial for health however, balance is essential in any physical activity. Individuals who engage in prolonged and intense exercise should ensure medical supervision and proper nutrition.
