Muscle Contraction Types Quiz

Why is understanding muscle contraction types important in designing exercise programs?

• It helps in choosing the right exercises for different goals.

• It allows for faster muscle growth.

• It ensures that all exercises are isotonic.

• It prevents any form of muscle injury.

What happens during an isometric contraction?

• The muscle tension decreases.

• The joint angle remains constant.

• The muscle lengthens.

• The muscle shortens.

Which type of contraction allows a muscle to produce the most force?

• Concentric

• Eccentric

• Isometric

• Isotonic

Why are eccentric contractions more energy efficient?

• They require more ATP.

• They use less ATP.

• They involve more muscle fibers.

• They are slower than other contractions.

What does isotonic contraction mean?

• Same movement speed

• Same muscle tension

• Same joint angle

• Same muscle length

How do isokinetic machines function during exercise?

• They maintain constant muscle tension.

• They vary the speed based on muscle force.

• They keep the joint motion at a constant speed.

• They ensure the muscle length remains unchanged.

During a pushup, which muscles contract concentrically?

• Abs and obliques

• Quads and hamstrings

• Biceps and deltoids

• Triceps and pec major

In a side plank, which type of muscle contraction is primarily involved?

• Isokinetic

• Isometric

• Eccentric

• Concentric

What role do the oblique muscles play during a side plank?

• They relax to allow movement.

• They contract isometrically to support the hips.

• They lengthen to stabilize the body.

• They shorten to lift the hips.

Which muscle group helps prevent the rib cage from collapsing during a side plank?

• Biceps

• Deltoid

• Quadriceps

• Triceps
