Heart Rate Reserve Formula:
| From: | To: |
Heart Rate Reserve (HRR) is the difference between your maximum heart rate (MHR) and resting heart rate (RHR). It represents the range of heart rates available for exercise and physical activity, providing a more personalized approach to training intensity than using maximum heart rate alone.
The calculator uses the HRR formula:
Where:
Explanation: HRR represents the full range of heart rates available for physical activity, from complete rest to maximum exertion.
Details: HRR is essential for creating personalized training zones, monitoring cardiovascular fitness improvements, and designing effective exercise programs tailored to individual fitness levels.
Tips: Enter your maximum heart rate and resting heart rate in beats per minute (bpm). For accurate results, measure your resting heart rate first thing in the morning before getting out of bed.
Q1: How do I measure my maximum heart rate?
A: The most accurate method is through a graded exercise test. Alternatively, you can use the formula: 220 - age, though this is an estimate and individual variations exist.
Q2: What is a good heart rate reserve?
A: A higher HRR typically indicates better cardiovascular fitness. While there's no universal "good" value, athletes generally have higher HRR values than sedentary individuals.
Q3: How is HRR used in training?
A: HRR is used to calculate training zones as percentages of your heart rate reserve plus your resting heart rate, creating personalized intensity targets.
Q4: Can HRR change over time?
A: Yes, as your fitness improves, your resting heart rate typically decreases, which increases your heart rate reserve even if your maximum heart rate remains the same.
Q5: What's the difference between HRR and maximum heart rate?
A: Maximum heart rate is an absolute value, while HRR accounts for your individual resting heart rate, making it a more personalized measure of your cardiovascular capacity.
