“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. Another fact is that youngsters also have a impressive recovery time, even faster than the well-trained adult endurance athletes. There was no evidence to prove it until now.
In the study, groups of children 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 were observed and compared. They were asked to perform two seven second resistance sprints, followed by one minute recovery while their aerobic energy output was measured. A second observation was based on the Wingate Cycle Test which measures anaerobic output by asking participants to cycle as fast as they can for 30 seconds. The participants’ heart-rate, oxygen levels and lactate-removal rates were checked after the cycling tasks to see how quickly they recovered. The researchers believe the findings could help develop athletic potential in children. “Our research indicates that aerobic fitness, at least at the muscle level, decreases significantly as children move into adulthood,which is around the time increases in diseases such as diabetes occur, ” Dr Ratel concluded. Not at least,”t seems that being a child might be healthy for us”; in fact, this is linked to the goal to maintain musles performance as the kids have.
