I think people who are born there have an advantage as they have more lung capacity etc. thats cos their body has adapted over the years etc.
training there should improve your fitness, it will get you tired quicker but if the body adapts back to the normal altitude then it would seem pointless, maybe the person needs to it because they would rather be out of breath after 3 miles then 5miles?
I dont see a few weeks changing your body much though, but im not an expert in this field either.
