Question

what is the ability of muscles to do work against resistance ?
○ a. persistence
○ b. endurance
○ c. flexibility
○ d. strength

Explanation:

To solve this, we analyze each option:

• Option a (Persistence) refers to continuing despite difficulties, not muscle work against resistance.
• Option b (Endurance) is about sustaining activity over time, not directly about working against resistance.
• Option c (Flexibility) relates to joint range of motion, not muscle work against resistance.
• Option d (Strength) is defined as the ability of muscles to exert force (do work) against resistance.

Answer:

d. Strength
