There is 2 types of contraction Isometric: As the muscle contracts‚ it remains the same length whilst the tension increases in an attempt to overcome the opposing force. Example: Holding a glass of water still in front of you. Isotonic: As the muscle contracts its length changes whilst the tension remains constant or develops to overcome the opposing force.

Animals have three types of muscles; skeletal‚ smooth‚ and cardiac. This lab however is only concerned with skeletal muscle. A special characteristic of skeletal muscle is their ability to contract or shorten via thin (actin) and thick (myosin) filaments (Flanagan‚2017). This gives a striated appearance which is a key distinguishing characteristic between other types of muscle (Flanagan‚2017). Skeletal muscle is also multinucleated. Skeletal muscle needs plentiful amounts of energy to be able to
