Length tension relationship::
the tension generated by a muscle contracting isomertrically depends on the initial length in human beings maximal muscle tension can be generated when the muscle is approximately at in maximal natural length in the body beyond 100% of resting length the contraction becomes passive and the active contraction decreases however total tension remains almost steady as it is the sum of both active and passive forces developed the passive tension is due to the elastic component of the muscle that tries to bring the length of the muscle to normal size
