HOW WOULD TRAINING AT HIGHER ALTITUDES INCREASE THEIR BREATHING EFFICIENCY?

Cellular Respiration & Fermentation
The percentage oxygen in the air is at 21%.
The air pressure at higher altitude is 30% lower.
WHY IS THE AIR PRESSURE LOWER AT HIGHER ALTITUDE?
pressure decreases with increasing altitude
at higher elevations, there are fewer air molecules above a given surface than a similar surgace at lower levels.
the air in the atmosphere is always pressing down on you. therefore...
since the air pressure decreases, you would have less air pushing down on you than you would normally.
how would training at higher altitudes increase their breathing efficiency?
In high-elevation environments, you attract less oxygen per breath than you would at lower altitudes. That implies every breath will deliver less oxygen to your muscles. When they compete at lower heights, they get a natural boost to the muscles when extra oxygen is available.
WHAT HAPPENS INSIDE THE BODY THAT BENEFITS THE ATHLETE?
Athletes do this because the air is "thinner" at high altitudes. In other words, there are fewer oxygen molecules per volume of air. Erythropoietin, one of the body's hormones, triggers the production of more red blood cells to aid in delivery to the muscles. With more red blood cells, the athlete's circulatory system is able to carry a greater amount of oxygen to their skeletal muscles. This gives the athlete a significant advantage when competing in long distance, endurance sports that utilize their oxidative metabolism. Oxidative metabolism is a chemical process in which oxygen is used to make energy from carbohydrates. In conclusion, its easier in lower altitude because your body is adapted to create more ATP.
