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.
A quick review of excitation-contraction coupling in skeletal muscle: The sarcoplasmic concentration of calcium in skeletal muscle is kept very low by the action of Ca-ATPases which remove the calcium and sequester it in the sarcoplasmic reticulum. When an action potential depolarizes the muscle cell membrane, it also travels into the body of the cell via the t-tubules.
