Question

the ability of muscles to exert a force one time is known as
muscular strength.
speed.
power.
muscular endurance.

Explanation:

To solve this, we analyze each option:

• Muscular strength: Defined as the ability of muscles to exert a force in a single effort.
• Speed: Relates to how fast an action is performed, not muscle force exertion at once.
• Power: Combines strength and speed (force over time), not just single - time force.
• Muscular endurance: Is about repeated muscle contractions over time, not a single force exertion.

So, the correct option is the one matching the definition of single - time muscle force exertion.

Answer:

A. muscular strength.
