is the physiological process of shortening muscle fibres found in muscle tissues after stimulating from a motor neuron which regulates the exertion of force from the muscle. This process is kicked off by ATP in myosin filaments which detach from their actin filament and then swing back which causes the two separate filaments to slide in opposite directions. During this process, muscle fibres become shorter and thicker.
