Exercising at Altitude Improves muscular endurance and increases fitness through intensified aerobic and anaerobic training sessions. Training under intermittent hypoxia also prepares an individual best for competition or hiking at altitude by improving breathing economy, and the ability to stay saturated with oxygen while working hard at altitude.
The result being you’ll feel less fatigued and will recover quicker, which means you can increase your training intensity and move up a gear. Studies have proven positive effects such as improved repeat sprint performance, increased anabolic hormonal responses and increased red blood cell mass.
This study done on elite male triathletes shows 7% increase in VO2max and a 7.4% increase in mean maximal power ouput/Kg body weight (Wmax) after 10 days of exercise training at a simulated altitude of 8000ft/2500m.
