What causes pain in legs while running?

Answer 1

Anytime your muslces exert themselves they start to use the sugars in there cells for energy via a system called aerobic, this means the utilize oxygen as well.  Once the available oxygen is used up the cells are still demanding energy and so the start to developed energy via anaerobic, or lack of oxygen, system.  This system has a byproduct called lactic acid.  When the lactic acid builds up in the muscles-that is what causes the pain and cramping in your legs.  As you become consistently active, your muscles develop a better system of getting oxygen to the muscles and it may take longer or harder exercise to get the same lactic acid buildup.  However, eventually everyone that exercises for prolonged times will develop lactic acid and that is why your muscles are sore after running or any type of exercise.

Answer 9

As your legs run, the muscles create lactic acid as a biproduct. There's a lot of science behind but basically this chemical is what causes the burning sensation you feel in your legs.

To decrease the onset of lactic acid buildup, try warming up and stretching first. Also, the better in shape you are and the more you've trained, the slower the lactic acid will buildup in your muscles. Your muscles will also be able to clear it more efficiently.

Answer 10

Your legs aren't used to doing so much exercise so your muscles stretch.. and it hurts : (
