New research shows that kids around the world, on average, need an extra 90 seconds to run a mile than did kids in 1975. Increased body weight and a lack of exercise are factors.
Scientists haven't yet discovered how many children, upon hearing of time travel, dream of heading back a few decades to visit their parents as kids. Stripped of height and authority, would parents be any fun? Maybe they would just be bossy, brutish, and short. Would they know how to play tag?
If today's kids could wangle such a playdate, however, they might find themselves left in the sandbox dust, according to new research presented at Tuesday's annual meeting of the American Heart Association.
Exercise physiologists at the University of South Australia who analyzed research on 25 million children around the world determined that today's kids, on average, take a minute and a half longer to run a mile than did kids in 1975. The studies measured how far children of different ages could run in 5 to 15 minutes, and how quickly they could run distances up to two miles.
