2. Athletes who have trained at high altitude often perform better than those who complete the same level of training at sea level. This is because training at high altitude causes their body to produce more red blood cells. a. Explain why having more red blood cells would give them a competitive advantage b. What risks are involved in increasing the number of red blood cells?
