Quick Answer. Calcium is a crucial part of muscle contraction. The ionic element is released from muscles during contraction and relaxation. The release of calcium helps propagate the muscle contraction and relaxation stages.
Calcium is an ion that acts as some type of cellular signal in nearly all cells. In muscle cells, it signals the cell to contract. 1  In resting muscle the concentrations of Ca2+ near the muscle fibers are quite low (~0.1mM)  Ca2+ is stored in a complex of vesicles known as the sarcoplasmic reticulum (SR)
