Many of the calculators previously featured here no longer function on modern browsers, so we have moved them to the updated version here:

Football: FIFA World Cup 2010

Amount of oxygen in the air
(% of sea level value)

Maximum aerobic exercise capacity
(% of sea level value)

**Randomly selected altitude**
At this altitude exercise capacity is 93%, and the percentage of oxygen in the atmosphere is 77%, of what it would be at sea level.

Football at high altitude

Many of the FIFA 2010 World Cup matches will be played at moderate altitude. The calculators shown here can demonstrate the effect that this might have on a players performace. Even a 1% drop in performance might be enough to make the difference between winning and losing, so adequate altitude training is essential. The altitude also affects the flight of the ball, such that an average goal kick would fly 4 yards further, because there is less drag.
