Heart Rate Reserve Formula:
| From: | To: |
Heart Rate Reserve (HRR) is the difference between your maximum heart rate and your resting heart rate. It represents the range of heart rates available for exercise and physical activity, providing a more personalized approach to heart rate training zones.
The calculator uses the Heart Rate Reserve formula:
Where:
Explanation: The formula calculates your maximum heart rate based on age, then subtracts your resting heart rate to determine your available heart rate range for exercise.
Details: HRR is crucial for establishing personalized exercise intensity zones, monitoring cardiovascular fitness improvements, and creating effective training programs tailored to individual fitness levels.
Tips: Enter your age in years and resting heart rate in beats per minute (bpm). For accurate RHR measurement, take your pulse first thing in the morning before getting out of bed.
Q1: Why use 220 - age for maximum heart rate?
A: This is a widely accepted estimation formula, though individual variations exist. For more accuracy, maximal exercise testing can provide actual maximum heart rate.
Q2: How can I use HRR for exercise training?
A: HRR is used to calculate training zones (e.g., 60-80% of HRR plus RHR for moderate to vigorous intensity exercise).
Q3: What is a normal HRR value?
A: HRR typically ranges from 100-150 bpm in healthy adults. Higher HRR generally indicates better cardiovascular fitness.
Q4: How does fitness level affect HRR?
A: As fitness improves, resting heart rate typically decreases, which increases HRR and indicates improved cardiovascular efficiency.
Q5: Are there limitations to this calculation?
A: The 220-age formula is an estimation and may not be accurate for everyone. Individual genetics, fitness level, and medications can affect actual maximum heart rate.
