Neuromuscular System Adaptations - Long-Term Exercise

Multiple Choice

What is a motor unit?

• Medulla Oblongata

• The properties of a muscle fibre

• Neuromuscular Junction

• A motor neuron and its muscle fibres

Multiple Choice

What is the process of either all or none of the muscle fibres in a motor unit contracting known as?

• Maximum contraction

• All or nothing law

• Motor unit recruitment

• Sliding filament theory

Multiple Choice

Can a motor unit partially contract?

• Yes

• No

Multiple Choice

What happens if the threshold is met or surpassed?

• Motor unit relaxation

• Motor unit contraction

• Partial motor unit contraction

Multiple Choice

A muscle is made up of multiple motor units

• True

• False

Multiple Choice

Do all motor units in a muscle always contract at the same time?

• Yes

• No

Multiple Choice

What is nervous inhibition?

• The increase of an action potential

• A way to allow for maximum contraction

• The cause of the anticipatory rise

• A protective mechanism that prevents a muscle from overworking

Multiple Choice

The role of a GTO is to detect levels of tension within a muscle

• True

• False

Multiple Choice

High intensity training can increase the threshold of the GTO

• True

• False

Multiple Choice

What will this increase in threshold achieve?

• Less powerful muscle contractions

• More powerful muscle contractions

Open Ended

Why could the increase in threshold cause injury?
