What are the effects of extreme endurance running on red blood cells?

Extreme endurance running can cause red blood cells to become less flexible, potentially reducing their ability to carry oxygen, and exhibiting signs of damage and accelerated aging.

Do ultramarathon athletes experience inflammation?

Yes, ultramarathon athletes participating in long races show signs of inflammation across the body.

How does race distance affect red blood cell damage?

The longer the race distance, the more blood cells are lost and the more damage accumulates, with significant impacts seen between marathon and ultramarathon distances.

Red blood cell flexibility decreases after long races.

Extreme Running Accelerates Aging, Study Finds

Recent research indicates that extreme endurance running can lead to accelerated aging and damage to red blood cells.

Scientists found that ultramarathon athletes' red blood cells became less flexible after long races, potentially reducing oxygen transport efficiency.

These athletes also exhibited signs of inflammation and a decline in DNA-protective molecules. The study analyzed samples from runners before and after races, including a 171km ultramarathon.

The damage observed in red blood cells and increased inflammation are linked to accelerated aging. Researchers note that damage intensifies with race length, with significant impact occurring between marathon and ultramarathon distances.

Further studies aim to understand the repair mechanisms and long-term effects of this exercise-induced damage, potentially informing strategies to improve athletic performance and blood storage techniques.
