Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax. Alternatively relaxation (failure) will also occur when ATP is no longer available. In order for a skeletal muscle contraction to occur; 1. There must be a neural stimulus. 2. There must be calcium in the muscle cells. 3. ATP must be available for energy. So, a few things can stop a contraction; 1. Energy system fatigue: There is no more ATP left in the muscle cell so it canât keep contracting. 2. Nervous system fatigue: The nervous system is not able to create impulses sufficiently or quickly enough to maintain the stimulus and cause calcium to release.
