When humans workout for a long period of time, the body's muscles may become sore. What process occurred in the muscle cells that made them sore?

Respuesta :

Answer:

When muscles are required to work harder than they're used to or in a different way, it's believed to cause microscopic damage to the muscle fibres, resulting in muscle soreness or stiffness. DOMS is often mistakenly believed to be caused by a build up of lactic acid, but lactic acid isn't involved in this process.
