Running extreme distances may strain more than just muscles and joints. New research suggests ultramarathons can alter red blood cells in ways that make them less flexible and more prone to breakdown, ...

Extreme endurance running damages red blood cells in ways that may affect their ability to function properly, according to a study published in the American Society of Hematology's journal Blood Red ...

For many years, scientists have been puzzled by individuals who live in high-elevation areas throughout the world. Surveys of high-altitude populations, from areas of the Andes to regions of the ...
