We can look at muscle fibers as being on a spectrum with slow twitch on one side and fast twitch on the other side. Type 1, which are slow twitch, uses oxygen to create energy. The upside is they can work for a longer period of time before fatiguing. The downside is they contract the…

Skeletal muscle is a tissue capable of making a wide range of functional demands, from performing highly precise movements for which little force is required, to maximum contractions, to maintaining the body’s posture. This versatility is due, in part, to the existence of several types of muscle cells or fibers, which have different functional, metabolic…
