Heart Rate Recovery Calculator
One minute heart rate drop with verdict.
What it does
Recovery pulse tells how fast the body stands down. After hard effort the rate should fall quickly in the first minute as vagal tone returns. A drop of 20 with normal verdict differs sharply from a drop of 8 that needs review.
The tool above subtracts one minute pulse from peak. Defaults of 170 to 150 give a 20 bpm drop with an 11.8 % fall and Normal recovery. Faster at 30 earns Fast recovery, while 8 earns Slow recovery with clinical review. Percent fall keeps big and small peaks comparable.
Context rules single readings. Heat, dehydration, caffeine, illness, and rate slowing medicines all move the drop. Fitness lifts it over weeks, so repeat the same protocol at the same time of day before judging change.
This page grades information only. It does not diagnose, clear exercise, or adjust medicines. Chest pain, fainting, or sustained abnormal rhythm needs prompt care.
How to use
- Enter the peak heart rate in bpm.
- Enter the pulse one minute later, seated.
- Read the bpm drop first.
- Read the verdict band.
- Read the percent fall for context.
- Repeat across weeks to see trends.
Formula
- peak
- Highest pulse near end of effort, in bpm.
- rec
- Pulse one minute after stopping, seated, in bpm.
- pct
- Share of peak lost in that minute.
One minute seated recovery after peak effort. At recovery at or above peak there is no drop to grade. Medicines, heat, and fitness shift results, so trends beat single readings.
Worked example
Example: 170 to 150 in one minute
Defaults: peak 170 with 150 at one minute after stopping. Measure seated, same device.
- Inputs: peak 170 bpm with 150 bpm at one minute.
- Drop: 170 minus 150 is 20 bpm drop.
- Percent: 20 / 170 times 100 is 11.8 % fall.
- Verdict: 20 sits in 12 to 21, so Normal recovery.
- Slow below 12 needs clinical review. Tool shows 20 bpm drop with Normal recovery.
Reference table
| Peak to 1 min | Drop | Band |
|---|---|---|
| 170 to 150 | 20 bpm drop | Normal recovery |
| 180 to 150 | 30 bpm drop | Fast recovery |
| 160 to 152 | 8 bpm drop | Slow recovery |
| 150 to 130 | 20 bpm drop | Normal recovery |
| 190 to 160 | 30 bpm drop | Fast recovery |
Limits
- Information only. No diagnosis or clearance.
- One protocol assumed. Standing versus seated differs.
- Medicines ignored. Beta blockers blunt the drop.
- Single reading noisy. Trends count.
Common mistakes
- Measuring during cool down jogging instead of seated.
- Mixing devices with different lags.
- Testing sick or overheated and judging fitness.
- Reading percent without the bpm drop.
- Acting on one slow reading alone.

Quick checks. Answers sit tucked under each question.
Peak 180 with 150 at one minute?
Drop is 30 bpm with 16.7 % fall. Fast recovery.
Peak 160 with 152 at one minute?
Drop is 8 bpm with 5 % fall. Slow recovery, discuss with a clinician.
Questions
How is HRR figured?
Peak minus one minute pulse. Here 20 bpm drop.
What counts as normal?
22 and up fast, 12 to 21 normal, below 12 slow with clinical review. Here Normal recovery.
Is one reading enough?
No. Heat, dehydration, caffeine, and beta blockers all shift the drop.
How do I measure it right?
Seated right after stopping, same monitor, no cool down sprint tacked on.
When do I call a clinician?
Yes when the drop stays below 12 or symptoms appear. Bring the numbers.
Does this diagnose heart disease?
No. This is fitness information only, not a diagnosis.
