Question

Athletes are often trained at high altitude because

• A. Training at high altitude increase muscle mass
• B. Training at high altitude increases the number of red blood cells
• C. There is less change of an injury at high altitude
• D. Athletes sweat less at high altitude

Answer 1

The correct option is B Training at high altitude increases the number of red blood cells

At higher altitudes, the air becomes thinner hence the amount of oxygen is less. Hence when an athlete trains at higher altitude the body will produce increased amount of red blood cells to carry more oxygen. This increased red blood cell count enables the athlete to perform better in a match. Thus the correct answer is option B.
