Which type of muscle is under voluntary control?

• None of the above

• Skeletal Muscle

• Cardiac Muscle

• Smooth Muscle

Which type of muscle contraction involves muscle shortening?

• Isokinetic

• Isometric

• Isotonic Concentric

• Isotonic Eccentric

What is the principle that states the strength of a response is not dependent on the strength of the stimulus?

• Reciprocal Inhibition

• All-or-None Principle

• Synergist Principle

• Antagonist Principle

Which type of muscle fibre is more resistant to fatigue and provides endurance?

• Type IIx (Fast Glycolytic Fibres)

• Type I (Slow Twitch Fibres)

• Type IIb (Fast Twitch Fibres)

• Type IIa (Fast Oxidative Fibres)

What is the function of the antagonist muscle in a movement?

• Assists in the movement

• Contracts to generate force

• Relaxes or lengthens during contraction

• Prevents movement at another joint

What is the term for the phenomenon that prevents muscles from working against each other?

• Synergist Principle

• Fixator Principle

• Antagonist Principle

• Reciprocal Inhibition

Which type of muscle contraction involves a change in length without movement?

• Isokinetic

• Isotonic Eccentric

• Isotonic Concentric

• Isometric

What is the function of the fixator muscle in a movement?

• Relaxes or lengthens during contraction

• Prevents movement at another joint

• Assists in the movement

• Contracts to generate force

How do different types of muscle fibre affect our ability to exert forces in a sporting environment?

• Type I fibres provide quick bursts of power

• Type IIa fibres provide endurance

• Type IIx fibres resist fatigue

• Interplay between fibre types affects performance
