Researchers have discovered that children have the stamina and levels recovery of endurance athletes. fact, scientists say children's muscles recover "high-intensity exercise" a lot quicker than athletes. A study looked the performance levels children when they were cycling, and compared their fitness to that athletes. Researcher Dr Sebastien Ratel said: "We found the children used more their aerobic metabolism and were therefore less tired the high-intensity physical activities. They also recovered very quickly - even faster than the well-trained adult endurance athletes."

The researchers hope that their findings will help scientists better understand how the human body changes age. It could lead to advances the fight against diabetes and other diseases. Dr Ratel said the research was particularly important as more children were becoming less active. He warned: " the rise in diseases related to physical inactivity, it is helpful to understand the physiological changes growth that might contribute to the risk disease." He added that children should maintain their fitness as they grow and play as much as they could so they remain healthy as adults.
