Types of Muscle Contraction Quiz

What is an isotonic concentric contraction?

• A muscle produces tension but stays the same length.

• A muscle shortens and the origin and insertion move closer.

• A muscle lengthens while under tension.

• A muscle lengthens and the origin and insertion move further apart.

Which type of contraction involves a muscle lengthening while under tension?

• Isotonic eccentric contraction

• Isometric contraction

• Voluntary contraction

• Isotonic concentric contraction

What happens during an isometric contraction?

• The muscle changes length.

• The muscle produces tension but stays the same length.

• The muscle shortens and becomes fatter.

• The muscle lengthens and becomes thinner.

Which type of contraction is used to control movement on the downward phase?

• Isometric contraction

• Isotonic concentric contraction

• Isotonic eccentric contraction

• Voluntary contraction

What is the role of isotonic eccentric contraction?

• To produce tension without changing muscle length.

• To initiate voluntary muscle movement.

• To lengthen the muscle and resist the force of gravity.

• To shorten the muscle and move the origin and insertion closer.

Which contraction type is involved when a gymnast holds a crucifix position?

• Isotonic concentric contraction

• Isometric contraction

• Voluntary contraction

• Isotonic eccentric contraction

What occurs when isotonic contractions happen?

• The muscle changes length.

• The muscle stays the same length.

• The muscle does not produce tension.

• The muscle relaxes completely.
