    Oh, people with dominant Slow twitch is hard to develop FT. In other words, they can't have burst power, however they can enjoy long distance walking. Congrats

    muscles are made up of cells called muscle fibers. muscles contract (shorten)because the fibers do.but they do not all contract together.the number contracting at any one time depends on how much force is needed, e.g more fibers in your biceps contract when you lift book than when you lift a pencil.there are two different kinds of muscle fibers,slow twitch(so they are suited to activities that need endurance e.g jogging,long distance running and fast twitch(so they are suited to activities that need bursts of strength and power e.g sprinting and weightlifting .

    What are some features of different muacl fibre types?

    Muscle fibre types: features:- Characteristics of FT and ST fibres that you need to remember: Characteristic Slow twitch fibres Fast twitch fibres Capillary density high low Force of contraction low high Fatigability low high Peak force low high PC stores low high Mitochondria high low Triglyceride stores high low Training - it is possible to improve the endurance potential of FT fibres (i.e. give FT fibres more aerobic tendencies). It is, however, hard to develop FT characteristics with people who have predominantly ST fibres. Preferential treatment - the intensity of the task determines which muscle fibre type is preferentially recruited. If immediate and rapid response to a stimulus is required, then FT fibres will contract first, then ST fibres. However, ST fibres get preferential treatment if the task is of low intensity.
