Cue the sad trombone. America’s kids ranked 47 out of 50 countries measuring aerobic fitness — a key factor for overall health — in a study published in the British Journal of Sports Medicine. By comparison, Tanzania, Iceland, Estonia, Norway and Japan raced away with the top five slots. The least fit country: Mexico.
Research teams from the Children’s Hospital of Eastern Ontario and the University of North Dakota analyzed data on more than 1.1 million kids aged 9 to 17. Subjects were evaluated using a multi-stage fitness test also known as the “beep” test. How it works: You run back and forth between two points 66 feet apart to synchronized beeps. The point where you can’t reach the line before the beep, that’s your level.
