Kids have much greater energy levels than professional endurance athletes, scientists have discovered.

Parents hoping to tire out their little ones to ensure a good night’s sleep, be warned. Children also have a very impressive recovery time, and will be back to their hyperactive best quicker than parents can say ‘lie in,’ reports The Telegraph.

“We found the children used more of their aerobic metabolism and were therefore less tired during the high-intensity physical activities,” said Sebastien Ratel, Associate Professor in Exercise Physiology who completed this study at the Université Clermont Auvergne, France.

“They also recovered very quickly – even faster than the well-trained adult endurance athletes – as demonstrated by their faster heart-rate recovery and ability to remove blood lactate.

“This may explain why children seem to have the ability to play and play and play, long after adults have become tired.”

Researchers recruited 12 youngsters aged between nine and 11, 12 untrained men and 13 male endurance athletes who were national-level triathlon competitors or long-distance runners and cyclists.

All were asked to perform two seven second resistance sprints, followed by one minute recovery while their aerobic energy output was measured. On a second visit they were asked to complete the Wingate Cycle Test, which measures anaerobic output by asking participants to cycle as fast as they can for 30 seconds.

Because anaerobic exercise does not use oxygen it produces acidosis and lactate (often referred to as, lactic acid), which causes muscle fatigue. The participants’ heart-rate, oxygen levels and lactate-removal rates were checked after the cycling tasks to see how quickly they recovered.

It was found that children not only have fatigue-resistant muscles, but recover very quickly from high-intensity exercise – even faster than the well-trained adult endurance athletes.

During the Wingate test untrained adult’s power output fell by 51.8 per cent, and athletes by 41.8 per cent, but children’s only decreased by 35.2 per cent.

The researchers believe the findings could help develop athletic potential in children as well as improve our understanding of how our bodies change from childhood to adulthood.

  • There you go. That explains why as parents we’re always exhausted and can’t believe the boundless energy of our kids.

  • Some children move about in their sleep so they’re not still even then.

  • That’s why I always sent my children outside to play for a good few hours every day – even after going to school. They really need to run off that excess energy so they can get a good night’s sleep
