Children have muscles that work like those of endurance athletes, study finds – Health



Have you ever wondered why kids can walk around all day and never get tired? A recent study suggests that her muscles, like elite endurance athletes, resist fatigue.

The study, published yesterday in Frontiers in Physiology, urged young men, inexperienced men and endurance athletes to do high-intensity exercise, then saw how quickly their muscles fatigued and recovered

The researchers brought the participants You literally had to find out that the boys' muscles did not tire easily – even though they were at a similar level to the endurance athletes.

" You can recover faster than you Elite athletes … maybe that's why children recover so fast when they play sports or do sports. "

Are children as fit as endurance athletes?

Professor of Health Sciences Tim Olds at the University of South Australia said the study was interesting ̵

1; but stressed that this does not mean that small children are as fit as endurance athletes.

Aerobic vs Anaerobic: What's the difference?

  • The body generates energy in two ways: Aerobics Metabolism and anaerobic Metabolism
  • Aerobic energy production When we inhale oxygen during exercise and oxygen from the blood to the Muscles are transported. There it undergoes several chemical processes and produces energy.
  • Anaerobic energy production is based on energy stores that are already present in the body – there is no need for oxygen. Lactic acid, which causes fatigue, is a byproduct of anaerobic energy production.

"What it found is the way they recover more than endurance athletes than untrained adults," said Professor Olds, who is not affiliated with the study

To understand why children have such good stamina and recovery, you need to understand how the body generates energy.

"There are two ways to produce energy: one is aerobic … the other is anaerobic."

Anaerobic energy production produces lactic acid, explained Professor Olds, and when there is a high level of lactic acid in the muscles accumulates, this causes exhaustion.

"But children do not have as sophisticated anaerobic systems as the average adult … that's why they do not produce much lactic acid, and that's why they do not start after repeated seizures (exercise)."

The study also showed that the blood collection by the boys was faster than in endurance athletes, so they could recover quickly.

Implications for Young Athletes

As He also explains why 10-year-old boys are so tireless, Professor Blazevich said the study could be useful to show where the training efforts should be focused on young athletes.

"We all noticed that and now we have some evidence of why," he said.

" This shows us that children are actually pretty good at it to play, to stop, to play, to stop, to play, to stop. This could mean that it is much more enjoyable to do sports where they can only run around a lot than other sports like adults.

It is also helpful for families where children want to achieve something a higher level in sport by helping to identify weaknesses to target, said Professor Blazevich.

"It looks like its aerobic fitness very good, so we can target skill because they are usually less skilled, strength because relatively they tend to be weaker, and their high intensity or sprint ability, because they are naturally weaker in it than adults. This enables us to reach out to youth athletes about the areas they need to improve, "he said.

The study was small and involved 12 boys around the age of 10, 12 untrained male university students, and 13 male endurance athletes, Professor Blazevich This has been explained by limited access to endurance athletes at national level and ethical constraints on research on children.

"Being a child could be healthy for us"

Research is also a step towards better understanding of the child Developmental Risks Diseases such as cancer, cardiovascular disease and diabetes increase with age, according to senior author Associate Professor Sebastien Ratel of the University of Clermont Auvergne.

"With the rise of physical inactivity-related illnesses, it is helpful to understand the physiological changes with growth that could contribute to the disease risk," he said.

"Our research shows that aerobic fitness, at least at the muscle level, decreases significantly as children reach adulthood, leading to an increase in disease rates associated with diabetes.

" It will be of interest in future research Determine whether the muscle changes we observe are directly related to the risk of disease. At the very least, our results could be motivation for the practice of maintaining muscle strength when children grow up; it seems that a child could be healthy for us.
