Un nuevo estudio publicado en Blood Red Cells & Iron relaciona las carreras de larga distancia con el envejecimiento prematuro de los glóbulos rojos. Investigadores analizaron muestras de sangre de 23 corredores antes y después de participar en la carrera Martigny-Combes a Chamonix (40 km) y la Ultra-Trail du Mont-Blanc (171 km). El estudio demostró que estas carreras causan daño significativo a los glóbulos rojos debido al estrés físico, la inflamación y el estrés oxidativo, reduciendo su flexibilidad y acelerando su deterioro. El daño fue mayor en la UTMB. Los investigadores señalan que se desconoce el tiempo que tarda el cuerpo en reparar este daño y si tiene un impacto a largo plazo, por lo que se necesita más investigación.
