Question

fill in the blank question

the type of muscle contraction in which there is a change in length, but no change in tension is called a(n) contraction.

Explanation:

Identify the key terms in the question

The question asks for a type of muscle contraction characterized by:

• A change in muscle length.
• No change in muscle tension (constant tension).

Analyze the types of muscle contractions

Using the Muscle Contraction Types knowledge point:

• Isometric contraction: The muscle develops tension but does not change length (iso = same, metric = length).
• Isotonic contraction: The muscle changes length while maintaining constant tension (iso = same, tonic = tension).

Determine the correct term for the blank

Since the definition specifies a change in length with constant tension, the correct term is "isotonic".

Answer:

The type of muscle contraction in which there is a change in length, but no change in tension is called a(n) <blank>isotonic</blank> contraction.
