What is the muscle length-tension relationship? The muscle length-tension relationship describes how a muscle's ability to produce force (or tension) changes with its length during contraction. Muscles generate maximum active tension at their optimal resting length where there is the greatest overlap between the actin and myosin filaments, allowing for the most cross-bridge formations. A muscle that is too long or without adequate tension is challenging to contract or lengthen further. A muscle
