Question

Assertion (A): Circuit training improves both strength and endurance simultaneously.
Reason (R): Circuit training includes a series of exercises performed with minimal rest between stations.

• A. Both A and R are true, and R is the correct explanation of A.
• B. Both A and R are true, but R is not the correct explanation of A.
• C. A is true, but R is false.
• D. A is false, but R is true.

Hint:

To solve Assertion-Reason questions, read both statements independently to check if they are true.
If both are true, connect them using the word "BECAUSE" to see if the statement makes logical sense.
"Circuit training improves strength and endurance BECAUSE it features a series of exercises with minimal rest."
This logical connection helps you confidently choose Option (A).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Assertion-Reasoning questions require a structured two-step evaluation. First, you must analyze both statements independently to determine if they are factually correct. If both are true, you then evaluate whether the Reason provides the logical cause or underlying mechanism that explains why the Assertion happens.
Step 2: Detailed Explanation:
Let's analyze each statement step-by-step: 1. Evaluate Assertion (A): "Circuit training improves both strength and endurance simultaneously." - Circuit training is an exercise training framework created by R.E. Morgan and G.T. Adamson in 1953. It involves moving through a series of selected workout stations targeting different muscle groups (such as push-ups, squats, sit-ups, and sprints). Because the stations incorporate resistance-based movements, it builds muscular strength. Simultaneously, because the routine is sustained over time, it challenges the cardiovascular system. Thus, Assertion (A) is True. 2. Evaluate Reason (R): "Circuit training includes a series of exercises performed with minimal rest between stations." - By definition, a circuit layout features multiple workout stations arranged in a loop. Participants perform a high volume of repetitions at one station and then immediately transition to the next station with very short rest intervals (typically 15 to 30 seconds). Thus, Reason (R) is True. 3. Evaluate the Logical Connection: - Now, ask: Why does circuit training manage to improve both strength and cardiovascular endurance at the same time? - It is precisely because the exercises are structured as a continuous series (building strength via resistance work) with minimal rest periods between stations (keeping the heart rate elevated throughout the session to build aerobic/anaerobic endurance). Because the short rest intervals drive the dual conditioning effect, Statement R is the direct operational explanation for Statement A. Therefore, both statements are true, and R is the correct explanation of A. This matches option (A).
Step 3: Final Answer:
Both A and R are true, and R is the correct explanation of A.
