Acute strains are
caused by a direct blow to the body, overstretching or excessive muscle
contraction. Chronic strains are the result of overuse - prolonged,
repetitive movement - of muscles and tendons. Inadequate rest during
intense training can cause a strain.
Typical indication of
strain include pain, muscle spasm, muscle weakness, swelling,
inflammation and cramping. In severe strains, the muscle or tendon is
partially or completely ruptured, leaving a person incapacitated. Some
muscle function will be lost with a moderate strain, where the muscle or
tendon is overstretched and slightly torn. With a mild strain, the
muscle or tendon is stretched or pulled, slightly. Some common strains
