MUSCLE PHYSIOLOGY

Detailed explanation-1: -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-2: -Similar to a sprain, a strain may be a simple stretch of your muscle or tendon, or it may involve a partial or complete tear of the muscle and tendon. Symptoms of a strain may include pain, muscle spasm, muscle weakness, swelling, inflammation, and cramping.

Detailed explanation-3: -Symptoms of a strain can include: Pain and difficulty moving the injured muscle. Discolored and bruised skin. Swelling.

Detailed explanation-4: -A strain is a stretched or torn muscle or tendon. Tendons are tissues that connect muscle to bone. Twisting or pulling these tissues can cause a strain. Strains can happen suddenly or develop over time.

Detailed explanation-5: -Acute strains are caused by stretching or pulling a muscle or tendon. Chronic strains are the result of overuse of muscles and tendons, through prolonged, repetitive movement. Inadequate rest during intense training can cause a strain.
