But the truth is that athletes who collapsed after endurance events develop very low blood pressure only when standing (exercise-associated postural hypertension, or EAPH). The symptoms of EAPH are caused by this sudden onset of a falling blood pressure, which results in an inadequate blood supply to the brain (cerebral ischemia). In that article he wrote, “The most common benign cause of collapse is low blood pressure due to blood pooling in the legs after cessation of exercise (as in ...
As a result, many athletes with EAHE received intravenous fluids for the treatment of altered states of consciousness supposedly caused by dehydration. Since the mild levels of dehydration (3-8%) encountered in ultramarathon runners and Ironman triathletes do not cause kidney and liver failure, so coma and convulsions in endurance athletes are not caused by dehydration. An altered blood flow to the brain does not occur in EAHE or in dehydration at the mild levels measured in endurance ...
