In the study, the researchers asked three groups (boys aged 8-12, untrained adults and endurance athletes) to perform cycling tasks
During the tasks, the researchers evaluated how each participant's body produced energy, both aerobically (using oxygen from the blood ) as anaerobically (do not use oxygen).
The heart rate, oxygen levels and lactate elimination rates of the participants after the cycling tasks were reviewed to see how quickly they recovered.

Results revealed that in all tests, children outnumbered untrained adults.
Dr. Ratel said: "We found that children used their aerobic metabolism more and therefore were less tired during the intensity physical activity stage.
" They also recovered very fast, even faster than well-trained adult endurance athletes, as demonstrated by their faster recovery of heart rate and their ability to eliminate blood lactate.
That's why children seem to have the ability to play, play and play long after adults get tired. "
Researchers suggest that the findings may help develop athletic potential in children.
Dr. Ratel said: "Many parents ask about the best way to develop their children's athletic potential.
"Our study shows that muscular endurance is usually very good in children, so it may be better to focus on other areas of physical activity such as sports technique, running speed or muscle strength."

"This can help optimize physical training in children so that they perform better and enjoy sports more"
The findings could also help improve our understanding of how our bodies change from childhood to adulthood .
Dr. Ratel added: "With the increase in diseases related to physical inactivity, it is useful to understand the physiological changes with growth that may contribute to the risk of disease."
"Our research indicates that aerobic fitness , at least at the muscle level, decreases significantly as children move into adulthood, which is more or less the time when diseases such as diabetes increase.
"It will be interesting in future research to determine if the muscular changes we have observed are directly related to the risk of disease."
"At least, our results can provide motivation for professionals to maintain muscle fitness as the children grow up; it seems that being a child could be healthy for us. "
