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 Question:
This question is in an Assertion-Reason format and evaluates our understanding of circuit training principles.
We must analyze the assertion and reason statements independently to determine if they are factually correct.
If both statements are true, we then determine if the reason logically explains the assertion.

Step 2: Detailed Explanation:
1. Let us first evaluate Assertion (A): "Circuit training improves both strength and endurance simultaneously."
2. Circuit training is an exercise method that moves participants through a series of stations targeting different muscle groups.
3. By combining resistance and cardiovascular exercises, it is designed to build strength and endurance at the same time.
4. This means Assertion (A) is factually correct.
5. Next, let us evaluate Reason (R): "Circuit training includes a series of exercises performed with minimal rest between stations."
6. In a standard circuit, exercises are performed one after another with very brief rest intervals of 15 to 30 seconds.
7. This structure of continuous physical work keeps the heart rate elevated, which builds cardiovascular endurance.
8. At the same time, the resistance exercises at each station challenge and build muscular strength.
9. This minimal rest structure is the exact mechanism that allows the system to build strength and endurance together.
10. Therefore, Reason (R) is true and provides the correct scientific explanation for Assertion (A).

Step 3: Final Answer:
Since both statements are true and the reason explains the assertion, the correct option is Option (A).
