Question

why does an athlete get muscle cramps on heavy exercise.​

Answer 1

Answer:

because anaerobic respiration is takes place in its muscles

Answer 2

Answer:

When the athletes undergo strenuous exercise, their body experiences a temporary deficiency of oxygen and the muscle cells begin to undergo anaerobic respiration to provide energy to the body. This leads to the production and accumulation of lactic acid, that leads to muscle cramps and pain in the body.  To provide relief, the lactic acid needs to be displaced. The impacted area can be massaged, rest can be given, a hot shower may also help. Slow breathing will help in early oxidation of the acid.
