Given the selection of men and women who participate in this style of racing every single calendar year, how perilous are extended length races?
How protected are marathons?
The BBC reports that most of the casualties that take place throughout a race involve minimal accidents these as muscle strains, sprains and strains. These have a tendency to recover promptly and on their have.
The announcer provides that dehydration is the most important issue marathoners have to get over. “In a hard operate on a hot, humid day, you can drop up to four liters of fluid by sweat and exhalation,” he suggests. “It is vital that the runners continue to be very well hydrated.”
Having said that, a increasing variety of research now website link prolonged-distance operating to previously undetected sudden heart ailments and difficulties, even even though there is no family background of related health and fitness issues.
In a review posted in December in the journal, Spanish researchers exposed that whole marathons can set tension on the heart.
