Any mountain climbers or doctors out there to answer this?
I'm no mountain climber, but was a year 12 PE student some time ago, and we looked at the phenom of why Kenyan runners are so good long distance...
How it works is that by training, and more specifically LIVING, at altitude, your body become more adept at more efficiently using oxygen, as there is less oxygen in the air. This process grows at a more rapid rate at the beginning, after 2-3 weeks, 'altitude training' has peaked, but the oxygen efficiency gains become negligible.
The effects of losing such 'altitude training' (or conditioning) don't kick-in straight away, so the players will maintain this, even if they play games at sea-level.
The problem with training at altitude, is that despite making the body more efficient at using oxygen, the body doesn't have the capacity to carry out the amount of work that it can carry out, when training just above sea-level.
The optimal method of training to provide MAXIMUM aerobic capacity, is by living at altitude, and training at just above sea-level. This isn't feasible in South Africa because the travel time between sea-level and altitude is not managable for training...
It is a misconception to think that we have a better prep than Germany and Serbia to this extent, as training at different levels preps the body accordingly. We seem to have given a higher amount of concern to the games at altitude, whilst teams training in Austria are trying to do a more balanced training.
Finally, having rabbited on about all that, the altitude effect in SA is not as significant as in some cases - there is unlikely to be any altitude poisoning!! It does play a big part when teams play against Bolivia in La Paz (for example), where it is 3,300 meters above altitude. Remember, they beat the Argies there 6-1 in this WCQ campaign!
Poisoning plays it's biggest part where a team is based and training at or around sea level, and travels to the highest games on the day before, or 2 days before the match - that is when altitude poisoning is at it's worst. If they come on the day, they won't get poisoned, but will obviously get a lower performance than usual.
Not sure where Ghana and Serbia are based during the WC, but if either are at sea-level, then we could see some impact. Conversely, we won't be at our best vs Germany - a good thing to remember whatever the result of our first game!!!
Go Aussies!!!!!!!!!!!!!!!
