The total tension is a combination of passive (non-contractile) & active (contractile units) tension. Generally, a muscle is capable of being shortened to approximately 1/2 of its normal resting length & stretched about 2 times its normal resting length. The distance between maximum elongation to maximum shortening is referred to as excursion, and usually a muscle has sufficient excursion to allow the joint to move through the joint’s entire [[Range of Motion|range]]. The action responsible for the contraction of a muscle occurs within a [[Muscle Cells (Myocyte)|sarcomere]] and force generation is dependent on the amount of overlap between thin and thick myofilaments [https://www.sciencedirect.com/science/article/pii/B9780128244814000093]. The greater the number of cross bridges attached to the actin filaments, the larger the contraction force [https://physoc.onlinelibrary.wiley.com/doi/abs/10.1113/JP280867]. The length-tension curve below summarizes the relationship between muscle length and tension during force production. It is important to note that two joint muscles undergo [[Active and Passive Insufficiency|active and passive insufficiency]] during simultaneous movements.
