Question

select the correct answer. what does muscular strength measure? a. the length of your muscle fibers as they contract and relax over a period of time b. the amount of force that a muscle or muscle group can exert in a single effort c. the ability of a muscle group to perform repeated movements for extended periods of time d. the range of motion in your body’s joints before and after flexibility exercises

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Muscle fiber length during contraction/relaxation over time is not what muscular strength measures. Muscular strength is about force, not fiber length over time.
• Option B: Muscular strength is defined as the amount of force a muscle or muscle group can exert in a single effort. This matches the definition.
• Option C: The ability to perform repeated movements for extended periods is muscular endurance, not strength.
• Option D: The range of motion in joints is related to flexibility, not muscular strength.

Answer:

B. the amount of force that a muscle or muscle group can exert in a single effort
