1. Slow twitch fibres (Type I): Slow twitch fibres contract slowly but can contract repeatedly over long periods. They have a good blood supply, hence they are âred fibresâ, and are suited to endurance activity using the aerobic energy system which relies on oxygen from the blood for the supply of energy.
Fast-twitch muscles break down into two categories: moderate fast-twitch (type IIa) and fast-twitch (type IIb or IIx). Moderate fast-twitch muscles are thicker, quicker to contract, and wear out more rapidly than slow-twitch. Fast-twitch, the most powerful and lowest in endurance, are activated when the body nears maximum exertion.
