Muscle Tears, Strains, Pulls
A strain to the muscle or muscle tendon is the equivalent of a sprain to ligaments. A muscle strain
occurs when muscle fibres cannot cope with the demands placed on them by exercise overload and
leads to tearing of the fibres. It is a contraction-induced injury in which muscle fibres tear due to
extensive mechanical stress. This mostly occurs as a result of a powerful eccentric contraction or
over-stretching of the muscle. Therefore, it is typical for non-contact sports with dynamic
characteristics such as sprinting and jumping.
Muscle lesions are classified as grade I, II, and III based on the number of fibres disrupted according
to clinical and imaging investigations.
