Exercise with no shortening of muscle fibers is known as isometric exercise. During isometric contractions, the muscle generates force without changing its length, meaning there is no visible movement in the joint. Common examples include planks, wall sits, and holding a weight in a fixed position. This type of exercise can help improve muscle strength and stability, particularly in specific positions.

The protein primarily involved in the shortening of muscle cells to produce movement is actin, which interacts with myosin. During muscle contraction, myosin heads bind to actin filaments, pulling them closer together and resulting in the shortening of the muscle fiber. This interaction is regulated by calcium ions and ATP, enabling coordinated contraction and relaxation of muscles.
