More info on simulated altitude training:
By exercising in a low-oxygen environment, the body makes adaptations to improve oxygen delivery to tissues and muscles, resulting in greater muscular endurance, improved power output and faster recovery.
The primary training methodology for endurance athletes is moderately intense exercise mixed with intervals consisting of 30 seconds to 2 minutes. The primary training method for sprint-based/power-based athletes (Football, Basketball, MMA) is very short-duration altitude interval sessions. Exercising at altitude will also increase the capacity to clear lactic acid from the muscles in a shorter time frame, enabling athletes to repeat sprints with faster recovery between each sprint.
