Q

a) What is altitude training?
b) Why do athletes use it as a method of
training?

A

a) Training at altitude where there is less oxygen.
b) The body adapts by making more red blood cells to carry oxygen. The additional oxygen carrying red blood cells is an advantage for endurance athletes returning to sea level to compete.
