1. What is Heart Rate Recovery?

Heart Rate Recovery (HRR) is a measure of how quickly your heart rate returns to normal after exercise. For men, it's calculated as the difference between maximum heart rate during exercise and heart rate two minutes after stopping exercise.

2. How Does the Calculator Work?

The calculator uses the HRR equation for men:

Where:

• \( HR_{max} \) — Maximum heart rate achieved during exercise (bpm)
• \( HR_{2min} \) — Heart rate measured exactly 2 minutes after stopping exercise (bpm)

Explanation: A higher HRR indicates better cardiovascular fitness and autonomic nervous system function.

3. Importance of HRR Measurement

Details: HRR is an important predictor of cardiovascular health. Slower HRR is associated with increased risk of cardiovascular events and mortality.

4. Using the Calculator

Tips: Enter your maximum heart rate during exercise and your heart rate exactly 2 minutes after stopping exercise. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a good HRR value for men?
A: Generally, HRR ≥12 bpm is considered normal, while HRR ≥22 bpm indicates excellent cardiovascular fitness.

Q2: How is HRR different for women?
A: Women typically have higher HRR values than men due to physiological differences in heart rate regulation.

Q3: When should HRR be measured?
A: HRR should be measured after standardized exercise testing, typically on a treadmill or stationary bike.

Q4: Can medications affect HRR?
A: Yes, beta-blockers and other heart rate modifying medications can significantly affect HRR measurements.

Q5: How can I improve my HRR?
A: Regular aerobic exercise, particularly high-intensity interval training, can improve HRR over time.
