ANATOMY

Detailed explanation-1: -However, there is concern that elevations higher than 3000 m can result in loss of training intensity and subsequent muscle wasting, 42 excess ventilatory work, and increased likelihood of acute mountain sickness. These side effects may cause stress on the athletes and can outweigh any positive erythropoietic benefits.

Detailed explanation-2: -Running at high altitudes decreases the amount of oxygen getting to the muscles. A low atmospheric pressure in the thin air makes the blood less oxygen-rich as it travels to the muscles. As the marathon proceeds and runners climb higher, the problem gets worse and worse as the runners’ oxygen demands increase.

Detailed explanation-3: -You’ll likely feel nauseous and lightheaded. You may vomit and have a headache. Different levels of altitude sickness have different symptoms: Symptoms of mild, short-term altitude sickness usually begin 12 to 24 hours after arriving at high altitude.

Detailed explanation-4: -Expensive. Altitude sickness. Difficult to train due to the lack of oxygen. Increased lactate production. Detraining due to the fact that training intensity has to reduce when the performer first trains at altitude due to the decreased availability of oxygen. Benefits can be quickly lost on return to sea level.
