    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

    Discuss the relationship between distribution of muscle fibre type and performance. How might exercise training modify or change a person’s fibre-type distribution? There are four different types of muscle fibres: type 1‚ type 2a‚ type 2x‚ and type 2c. “A single skeletal muscle contains fibres having different speeds of shortening and ability to generate maximal force: type 1 (slow-twitch) fibres and type 2 (fast-twitch) fibres.
