BTEC Sport: Muscle Contraction Quiz

What is isometric muscle contraction?

• A type of contraction that causes the muscle to change length as it contracts

• A type of muscle contraction where the muscle maintains its length as it develops tension

• A type of isotonic muscle contraction that causes the muscle to shorten in length as it develops tension

• A type of isotonic muscle contraction that causes the muscle to lengthen as it develops tension

What is concentric muscle contraction?

• A type of contraction that causes the muscle to change length as it contracts

• A type of muscle contraction where the muscle maintains its length as it develops tension

• A type of isotonic muscle contraction that causes the muscle to shorten in length as it develops tension

• A type of isotonic muscle contraction that causes the muscle to lengthen as it develops tension

What is eccentric muscle contraction?

• A type of contraction that causes the muscle to change length as it contracts

• A type of muscle contraction where the muscle maintains its length as it develops tension

• A type of isotonic muscle contraction that causes the muscle to shorten in length as it develops tension

• A type of isotonic muscle contraction that causes the muscle to lengthen as it develops tension

What are muscle fibres?

• The cells that form a muscle and contain the proteins needed for contraction

• A type of muscle fibre that is associated with slow contraction and low force

• A type of muscle fibre that is associated with fast contraction and medium force

• A type of muscle fibre that is associated with fast contraction and high force

What is type I muscle fibre?

• The cells that form a muscle and contain the proteins needed for contraction

• A type of muscle fibre that is associated with slow contraction and low force

• A type of muscle fibre that is associated with fast contraction and medium force

• A type of muscle fibre that is associated with fast contraction and high force

What is type IIa muscle fibre?

• The cells that form a muscle and contain the proteins needed for contraction

• A type of muscle fibre that is associated with slow contraction and low force

• A type of muscle fibre that is associated with fast contraction and medium force

• A type of muscle fibre that is associated with fast contraction and high force

What is type IIb muscle fibre?

• The cells that form a muscle and contain the proteins needed for contraction

• A type of muscle fibre that is associated with slow contraction and low force

• A type of muscle fibre that is associated with fast contraction and medium force

• A type of muscle fibre that is associated with fast contraction and high force

What does the 'all or none' law state?

• An individual muscle fibre can either contract or relax and is unable to vary the force produced during each contraction

• The brain sending information via nerves to control movements

• A type of specialised cell that transmits electrical signals

• The connection point between a motor neurone and the muscle fibre it innervates

What is nervous control?

• An individual muscle fibre can either contract or relax and is unable to vary the force produced during each contraction

• The brain sending information via nerves to control movements

• A type of specialised cell that transmits electrical signals

• The connection point between a motor neurone and the muscle fibre it innervates

What is a neurone?

• An individual muscle fibre can either contract or relax and is unable to vary the force produced during each contraction

• The brain sending information via nerves to control movements

• A type of specialised cell that transmits electrical signals

• The connection point between a motor neurone and the muscle fibre it innervates
