After a vigorous

Answer :

Muscle cramp is an involuntary sudden contraction of muscle. Muscle cramps are caused due to over usage of muscle i.e. long run, rapid exercise etc. Cramps are also caused due to dehydration, muscle strain, holding in position for a long time.

When you exercise, your blood is pumping faster around your body to make sure you have enough oxygen. But oxygen has to be constantly replenishing, and when you get out of breath, you do’t take in as much oxygen. It is called an oxygen deficit. This oxygen deficit can cause a buildup of lactic acid in joints, and contributes to cramps.


If you overexert (vigorous exercise) yourself, your muscles get depleted of oxygen, which causes a buildup of waste.


The waste products, primarily lactic acid, can cause your muscle to spasm.


Once the contraction begins, your spinal cord puts out signals for your muscle to keep contracting.


Additionally, if you don't warm up or stretch your muscles, they can't contract as smoothly and forcibly, which leads to cramps.
