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.
The fast-twitch muscle fibers are known as the white muscle, while the slow-twitch muscles fibers are known as red muscle. These two types of muscle fibers are engaged differently depending on what type of activity you are doing.lite sprinters may have up to 80% more white muscle fibers than red since their performance relies on this type of tissue. White muscle fibers fatigue at a much faster rate than their red counterparts because of a buildup of lactic acid, so they are only good for short bursts of speed.
