Type 1 fibres

These fibres are also known as slow twitch or slow oxidative fibres. They are red in colour, contract slowly but can keep going for long periods of time and withstand the onset of fatigue. These fibres are smaller than fast twitch fibres, develop less force and are best suited to aerobic endurance type activities.
