Strong athletes are super humans like them, fed by energy that seems to never run out.
However, a new study shows that human endurance has limits – and may be similar to all. Long-term coverage is about 2.5 times higher than organism’s metabolic metabolism or 4000 calories a day for most people, announced yesterday (June 5) in the journal Science Advances.
(Resting metabolism is a measure of how many calories the body burns for basic physiological needs such as maintaining body temperature and breathing.)
To determine whether there are limits to endurance, scientists analyzed data from some of the most extreme endurance events on the planet. They measured participants’ resting metabolism and calorie consumption in the US race, a month-long marathon series that brought runners from California to Washington. You do
By analyzing urine samples from the first and last stages of the race, the researchers found that after five months athletes burned far fewer calories than they did at the start of the race.
They also compared the results with previously published data from other activities such as marathons, swimming, hiking in the North Pole, the Tour de France and the early years of the US race. Researchers have found that it is not surprising that the longer the event occurs, the harder it is to burn calories.
While participating in relatively short-term activities, such as a marathon, the body can resist burning calories to a level far greater than a deadly metabolism.
For example, as long as a marathon runner can burn an average of 15.6 times more calories than at rest. After 23 days of the Tour de France, cyclists burn 4.9 times more calories to burn their metabolic rate at rest and on 95-day trips through Antarctic tourist calories with a metabolism 3.5 times higher.
They even checked the capacity limits of pregnant women.
The researchers also found that pregnant women had worked on a 2.2-fold resting metabolic rate just by giving birth to a baby in their womb. All this means that regardless of its activity – growing babies through the US or cycling – the body seems to have a limit on the amount of energy that can provide long-term.
The reason for this severe limitation may be due to the digestive system and the amount of calories that can be absorbed by the intestine per day, said co-author Hermann Ponter, associate professor of evolutionary anthropology at Duke University.
Athletes don’t just stop when they reach this 2.5 foot threshold. You can keep running, but the person cannot balance the number of calories consumed and the amount burned. So the body starts consuming its own resources and you start losing weight. This alone is not sustainable forever.
As far as you know, no one holds a level above the 2.5-fold threshold. “Science works if you are wrong, maybe one day someone will break the blanket and show us what we miss.
