Answer:
Athletic training increases red blood cell count.
A permanent move from sea level to high altitude increases red blood cell count.
Step-by-step explanation:
Athletic training increases red blood cell count.
An athlete has a comparatively increased muscle mass and requires an efficient oxygen means of transportation to the muscles during the course of the athlete running 4 to 5 miles a day over a period of 6 to nine months training or execrise.
A permanent move from sea level to high altitude increases red blood cell count.
The air is less dense at high altitudes and would posses a reduced amount of oxygen. The body make up for this lower concentration of oxygen in the air by yielding more RBCs to ensure that the same corresponding level of oxygen can be acquired or accumulated and then its transported by the blood.
