Orthostatic Heart Rate Test: Lying to Standing
After a few minutes lying quietly, students take their pulse, stand up slowly, and measure it again standing. The difference between the two is a simple marker athletes use to track fatigue, rest, and hydration over the weeks.
How to play
- Lie on your back on the yoga mat, eyes closed and breathing normally, in silence for 3 minutes; the teacher keeps time with the stopwatch.
- In the last 30 seconds, take your pulse at the wrist for 15 seconds and multiply by 4: that's your lying pulse.
- On the signal, get up slowly through sitting and stand still with arms relaxed.
- After 20 seconds standing, take your pulse for 15 seconds; take it again after 2 minutes standing.
- Write all three numbers on the sheet and calculate the difference between lying and standing (1 min).
- Interpretation (1 min): a rise of 10 to 20 beats is typical; if over several weeks the rise is a lot bigger than your usual, it may point to fatigue, poor sleep, or low hydration.
Rules
- Always get up slowly, passing through sitting.
- If you feel dizzy when you stand, crouch or sit down immediately.
- Everyone compares with themselves, never with classmates.
- Total silence during the lying phase so the pulse really settles.
Variations
Easier
Take the lying pulse and just one standing pulse, at 2 minutes.
Standard
Lying pulse, then standing at 20 seconds and 2 minutes, with the difference calculated.
Harder
Repeat the test at home on waking for a week and compare the data with hours of sleep.
Adaptations
- Limited mobility: compare resting pulse reclined with pulse sitting upright in the chair.
- Visual impairment or trouble finding a pulse: use a heart rate monitor or have a partner take it.
- Students prone to dizziness: stay seated instead of standing and take the second reading that way.
Learning goals
- Measure resting heart rate accurately in two positions.
- Interpret the heart rate response to a posture change as a recovery marker.
- Add a simple log to personal training tracking.

Teacher tip
This works best at the end of a calm class or as a tracking test: right after a very hard effort the numbers are skewed. Remind students it's a self-awareness tool, not a diagnosis.
