Would American 10 and 11-year-olds taking similar fitness tests fare much better? You would hope so, but if they bombed as badly as 300 Brits did in 2014, would you really be surprised?
Probably not, but either way, isn't it necessary to know for sure?
In 1998, researchers at the University of Essex in England administered a fitness test to a group of children aged 10 or 11. They repeated the test 10 years later with same-aged subjects. The second group was not only significantly heavier but also not nearly as fit as the first group.
