Lets do this pound per pound shall we.
Cardiovascular is extremely important as each racers heartrate increase to 140 beat plus for an extended period of time, lots of air consumed, lots of bike trainign for these fly weights. Strength in wrestling a hurtling 350+ pound beast into and out of corners while holding their miniscule weight in the saddle. Whatta think they weigh 115-130 lbs?
Then you look at an NFL lineman. Huge 6.5, 290 lbers throwing other huge 6.5 ft 290 lbers around with 30 second breaks in between. Sprinting 15 20 yards at a time. Hell even getting up after a play is a feat of strength.
NBA? same huge mammoths moving their feet faster than teh solid gold dancers on crack, not only covering the length of the court but also 10-12 feet vertically.
Lets not bring the baseball/steriods thing into it. I know those guys bat, throw, and run hard. Just don't think they have to be quite in the shape as the others as they have long periods of inactivity while playing the game.
Can we consider car racers? Sure but they aren't going to sell me on the physical strength part. Concentration and resistance to high Gs aside. They have to have the heart rate going on but really the wheel and the pedals don't give alot of resistance...
Boxers? Damn are they even human?
Taters Whore of an Ex wife? I don't even think she breaks a sweat
