When an athlete exercises, if he
or she is doing so at a level where more oxygen is being
used than can be replenished to their system, lactic acid
is formed.
As this builds up, it gradually forces the
body to slow down - it is the body's way of telling you
that you can’t carry on as you are.
What lactic acid
tolerance training will do for you is make your body
more efficient at reprocessing the waste products of
exercise, transporting oxygen to your blood and allowing
you to run nearer to maximal speed for a longer period
of time.
