Heart Rate Reserve Formula:
| From: | To: |
Heart Rate Reserve (HRR) is the difference between your maximum heart rate and resting heart rate. It represents the full range of heart rate response available to your body and is particularly useful in neurological physical therapy for prescribing exercise intensity.
The calculator uses the HRR formula:
Where:
Explanation: HRR provides a personalized measure of cardiovascular capacity that accounts for individual differences in resting heart rate.
Details: In neurological physical therapy, HRR is used to establish safe and effective exercise intensities for patients with neurological conditions. It helps create individualized exercise prescriptions that account for autonomic nervous system dysfunction often present in neurological disorders.
Tips: Enter maximum heart rate and resting heart rate in beats per minute (bpm). Both values must be valid positive numbers, with MHR greater than RHR.
Q1: How is maximum heart rate determined?
A: Maximum heart rate can be estimated using age-predicted formulas (220 - age) or measured through graded exercise testing under medical supervision.
Q2: When should resting heart rate be measured?
A: Resting heart rate should be measured after at least 10 minutes of complete rest, preferably in the morning before getting out of bed.
Q3: Why is HRR important in neurological rehabilitation?
A: HRR helps establish safe exercise intensities for patients with neurological conditions who may have altered autonomic regulation and cardiovascular responses.
Q4: How is HRR used to determine exercise intensity?
A: Exercise intensity is often prescribed as a percentage of HRR (e.g., 40-60% of HRR) plus resting heart rate.
Q5: Are there special considerations for neurological patients?
A: Yes, patients with neurological conditions may have blunted heart rate responses, autonomic dysfunction, or medications that affect heart rate, requiring careful monitoring.
