Heart Rate Recovery

Heart Rate Recovery

The VO2max, or Heart Rate Recovery assessment is an adaption of the Tecumseh step test that measures VO2Max using the smartphone camera and flash. The assessment follows a protocol where participants step up and down at a fixed cadence for 3 minutes followed by monitoring of heart rate recovery for 60 seconds. Data collected from this assessment includes VO2max estimation, heart rate estimation, and summarized video pixel intensities.

Validation Status

  • Validated in a cohort of 120 individuals spanning ages 20-80 by comparing to direct measurement of O2 consumption using mask and exercise protocol.
