Question

Strength is the ability of a muscle to get over resistance. Reason: Strength depend on cross section, morphology of the muscle and body weight.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Always ensure that when evaluating such questions, you consider both the correctness of the statements and whether one provides a valid explanation for the other.

Answer 1

The Correct Option is A

Step 1: Concept
Strength in muscles refers to the ability of a muscle or group of muscles to overcome resistance. The strength of a muscle can be influenced by several factors including its cross-sectional area, morphology (shape and structure), and body weight.

Step 2: Meaning
Cross-sectional area: This is the area of the muscle perpendicular to the direction of force production. Morphology: This encompasses various structural aspects such as fiber type distribution, arrangement, and innervation pattern. Body weight: The overall mass of an individual can affect how much resistance a muscle has to overcome.

Step 3: Analysis
The statement given in (R) mentions that strength depends on the cross-sectional area, morphology of the muscle, and body weight. This is accurate as these factors are well-established contributors to muscular strength. Cross-sectional area: A larger cross-section generally means more muscle fibers can contract simultaneously, leading to greater force production. Morphology: Different fiber types (fast-twitch vs slow-twitch) have varying capacities for generating force and fatigue resistance. Body weight: Heavier individuals may need stronger muscles to move their body mass effectively. The statement in (A), "Strength is the ability of a muscle to get over resistance," is also correct. This definition captures the essence of what strength entails, which is overcoming external forces or one's own body weight. Given that both statements are accurate and the explanation provided in (R) correctly elucidates why strength varies among individuals based on their physiological characteristics, option A is the most appropriate choice.

Step 4: Conclusion
Both the statement about strength and its definition are correct. The explanation given for the factors influencing strength accurately describes the underlying mechanisms. Final Answer: (A)
