<2> Ultramarathons May Damage Red Blood Cells and Accelerate Aging
<3> The Hidden Consequences of Extreme Running
<4> Red blood cells play a vital role in delivering oxygen to the body’s tissues, making them a crucial component of overall health. However, new research suggests that running extreme distances may have a profound impact on these cells, potentially leading to a range of negative effects.
<5> The study, published in Nature, found that ultramarathons can cause significant changes to red blood cells, making them less flexible and more prone to breakdown. This can lead to a range of problems, including reduced oxygen delivery to the body’s tissues and potentially even accelerating the aging process.
<6> The researchers behind the study used a combination of laboratory tests and mathematical modeling to investigate the effects of ultramarathons on red blood cells. They found that the intense physical demands of running extreme distances can cause significant mechanical stress on the cells, leading to changes in their shape and flexibility.
<7> In addition to mechanical stress, the researchers also found evidence of molecular damage linked to inflammation and oxidative stress.
