There are three types of energy involved in a muscle's contraction. There is metabolism, catabolism, and anabolism. Metabolism is the events that are carried out in the human body to create energy and other things needed for activity. Catabolism is the process during the organic matter is broken down and the energy is released, it takes place during increased movement. Anabolism is the energy-consuming process that substances are created, it takes place when there is little movement. All three of these work to gather in muscle contraction.
