Question

Recommendation for developing and maintaining cardiovascular fitness in healthy adults is:

• A. 3 days/week for 40 minutes/day at an intensity of 10-11 on the RPE (Rate of Perceived Exertion) Scale
• B. 3-5 days/week for 20-60 minutes/day at an intensity of 12-16 on the RPE (Rate of Perceived Exertion) Scale
• C. 5 days/week for 60 minutes/day at an intensity of more than 16 on the RPE (Rate of Perceived Exertion) Scale
• D. 3 days/week for 20 minutes/day at an intensity of 10-11 on the RPE (Rate of Perceived Exertion) Scale
• E.

Hint:

For optimal cardiovascular fitness, aim for moderate intensity (RPE 12-16) for at least 20-60 minutes, 3-5 days per week.

Answer 1

The Correct Option is B

Step 1: Understanding cardiovascular fitness recommendations.
Cardiovascular fitness is important for overall health and involves activities that increase the heart rate and improve the functioning of the heart and lungs. The American Heart Association and other health bodies recommend specific frequency, duration, and intensity levels for optimal cardiovascular health.
Step 2: Analyzing the options.
- (1) 3 days/week for 40 minutes/day at an intensity of 10-11 on the RPE scale: This is too low in frequency and intensity for optimal cardiovascular fitness.
- (2) 3-5 days/week for 20-60 minutes/day at an intensity of 12-16 on the RPE scale: Correct. This recommendation falls within the optimal range for cardiovascular fitness for healthy adults, balancing duration, frequency, and intensity.
- (3) 5 days/week for 60 minutes/day at an intensity of more than 16 on the RPE scale: This intensity is too high for the majority of healthy adults and might lead to overtraining.
- (4) 3 days/week for 20 minutes/day at an intensity of 10-11 on the RPE scale: This is too low in both intensity and duration for effective cardiovascular training.
Step 3: Conclusion.
The correct recommendation is (2), which suggests 3-5 days a week with 20-60 minutes per session at moderate intensity.
