For the sprinters out there (especially track, points race) looking for a boost to anaerobic performance, if you do not have access to a hypobaric chamber, you should do your sprint training high in the mountains.
This article seems to indicate that sprint training at high elevations, compared to near sea level, causes adaptations in the body that allow greater blood flow and possibly better waste removal from the fast twitch muscles, thereby increasing the number of all out sprints one could perform before exhaustion.
