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.
Muscles that need to be contracted much of the time (like the heart) have a greater number of Type 1 (slow) fibers. When a muscle first starts to contract, it is primarily Type 1 fibers that are initially activated, then Type 2A and Type 2B fibers are activated (if needed) in that order.
