Answer :
Fast fibres have low resistance to fatigue and have quick twitches.
What is fast fibres?
- Fast-twitch muscle fibres produce larger and more potent forces, but only for brief periods of time before quickly becoming exhausted.
- They are frequently referred to as white fibres or type II since they are more anaerobic and have less blood supply.
- Fast-twitch fibres often have fewer mitochondria and a higher density of glycogen, an energy source similar to high-octane fuel that can be swiftly used to provide large amounts of power and energy.
- The body primarily uses fast-twitch muscle fibres only when quick, forceful actions are required. utilisation of energy. Energy is used by slow-twitch muscles gradually and reasonably evenly, which prolongs its duration. This enables them to work for an extended period of time without running out of energy.
