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.
Magnesium ions found in the fluid surrounding the cells generate a small electrical charge in response to the calcium ions and propels the calcium ions back across the calcium sensitive potassium pump in the cell membrane. This stimulates potassium ions to flow out of the cell, which produces muscle cell relaxation.
