Serum parameters and energy balance during the Yukon Arctic Ultra: a multistage ultramarathon in Arctic conditions
A considerable energy deficit was identified in almost all athletes, which resulted in the loss of both lean mass and fat mass. Serum cardiac, lipid, and inflammation markers were altered significantly, indicating severe stress. It remains to be seen whether such events contribute to pathological sequelae or are merely temporary without clinical relevance.
