Motocross: The World's most demanding sport

Motocross is the world's most demanding sport, according to studies carried out over the years.

Research comparing riders to top athletes from other demanding sports like football, basketball, American football and track athletics, has shown that motocross riders were at a higher level of physical fitness. 

Another study carried out by the University of Florida showed that the cardiovascular demands of MotoX riders were actually higher than have been reported for professional road cycling.

And as if those studies weren't proof enough, Google even says it's the most demanding sport in the world which means it must be true...
