Muscular strength is best described by __________.

• A. the flexibility of a muscle during movement
• B. the speed at which a muscle can contract
• C. the maximum amount of force a muscle can produce in a single effort
• D. the ability of a muscle to sustain repeated contractions over time

Answer: (C)

Verified step by step guidance

1. Step 1: Begin by understanding the concept of muscular strength. Muscular strength refers to the ability of a muscle or group of muscles to exert maximum force against resistance in a single effort.
2. Step 2: Analyze the options provided in the question. Each option describes a different aspect of muscle function, but only one aligns with the definition of muscular strength.
3. Step 3: Eliminate incorrect options systematically. For example, 'the flexibility of a muscle during movement' refers to range of motion, not strength. Similarly, 'the speed at which a muscle can contract' describes muscular power, not strength. Lastly, 'the ability of a muscle to sustain repeated contractions over time' refers to muscular endurance.
4. Step 4: Focus on the correct option: 'the maximum amount of force a muscle can produce in a single effort.' This matches the definition of muscular strength as it emphasizes the peak force a muscle can generate.
5. Step 5: Reinforce your understanding by considering real-life examples, such as lifting a heavy weight in a single repetition, which demonstrates muscular strength.
