PPT-Muscle Fibre Types

A muscle fibre is a long cylindrical muscle cell held together in bundles to make up an individual skeletal muscle Human skeletal muscles consist of a mixture of each type of muscle fibre The relative proportion of each fibre type varies in the same muscles of different people eg Elite marathon runners have a greater proportion of slow twitch fibres and elite sprinters have more fast twitch fibres. Muscles. : . Types, Fibres & Movement patterns . Types of Skeletal Muscle:. Within our skeletal muscle we actually have . 2 types of muscle fibre . called . fast. and . slow twitch . fibres, related to the speed in which they contract.. Fast or Slow?. Skeletal muscles contain two main types of fibers, which differ in the primary mechanisms they use to produce ATP, the type of motor neuron innervation, and the type of myosin heavy chain expressed. The proportions of each type of fiber varies from muscle to muscle, from animal to animal, and from person to person.. To know the structural and functional differences between different types of muscle fibre.. To know how muscle fibre type affects sporting performance.. To understand the function of motor units in muscle contraction.. To know the structural and functional differences between different types of muscle fibre.. To know how muscle fibre type affects sporting performance.. Types of Muscle Fibre. Slow Twitch Fibres (Type 1). Nematoda: roundworms have no circular muscles to antagonize their longitudinals; they locomote using helical crossed-fibre arrays of inextensible collagen.. Echinodermata: starfish tube feet as an example of hydraulic skeletons; and they also use helical crossed-fibre arrays of collagen in the walls of their tube-feet..
