Types of Muscle Contractions

What happens when you make a muscle? It depends on what muscle contraction you are using. There are three types:

1. Concentric contraction: Widely known as muscle contraction. While they do look nice, the force generated by the muscle is less than the muscle’s maximum as the muscle shortens. It uses more energy than the other two types, and it generates the least amount of force.
2. Eccentric contraction: The external force on the muscle is greater than the force that the muscle can create, which then the muscle is forced to lengthen due to the high external load. The maximal force generated by the muscle is the highest, but the energy consumption is the lowest.
3. Isometric contraction: This contraction creates force without changing muscle length. It requires high amounts of energy through the force generated by the muscle. This force is equal to the external load.
