What is a voluntary muscle?
Voluntary muscles are under our control, you can choose when to contract or relax them e.g Bicep
What shape are voluntary muscles?
They are usually made up of cylinder shaped fibres and are long and thin however when they are contracted they turn fat and shorter
What are slow twitch muscle fibres?
Suit endurance activities-can work for long periods of time
Darker in colour because they contain myoglobin, a red pogament that transport oxegen to working muscles
What are fast twitch muscles (type IIa)
Used in anaerobic work which can be improved through endurance training. Increase their resistance to fatigue.
What are fast twitch muscles (type IIx)
Used in anaerobic work they can generate more power than other muscles fibres but fatigue quickly
