MUSCLE PHYSIOLOGY

Detailed explanation-1: -A muscle strain occurs when muscle fibers cannot cope with the demands placed on them by exercise overload and leads to tearing of the fibers. It is a contraction-induced injury in which muscle fibers tear due to extensive mechanical stress.

Detailed explanation-2: -A muscle strain is an injury to a muscle or a tendon-the fibrous tissue that connects muscles to bones. Minor injuries may only overstretch a muscle or tendon, while more severe injuries may involve partial or complete tears in these tissues.

Detailed explanation-3: -Strains are a twist, pull and/or tear of a muscle and/or tendon. Tendons are cords of tissue that connect muscles to bones.

Detailed explanation-4: -There are a number of types of muscle injury that can occur: laceration, contusion, degenerative diseases (eg Muscular Dystrophies) and strain.
