Build your analysis profile

Only ECG data is required. Add recording context when available so the report can separate rest / sleep analysis from workout and standardized interval-test analysis.

Dynamic one-minute efforts

1 minute × 3+

Record one continuous ECG file from the start of the warm-up until your heart rate has returned to baseline after the final effort. Keep the effort, terrain, equipment, and recovery posture as consistent as possible between tests.

  1. Warm up for 10 minutes. Continue recording and settle into a repeatable starting condition before the first effort.
  2. Complete one hard but controlled effort for exactly 1 minute. The test is for comparison, not an all-out finish.
  3. Recover until heart rate returns to baseline. Start the next effort only after HR is within the baseline tolerance for the full hold time.
  4. Repeat until 3 or more efforts are complete. Continue recording through the final recovery, then upload the CSV or ZIP once.

Each effort is fixed at 1 minute and the protocol dynamically infers intervals. Recovery length varies: wait for baseline rather than starting on a fixed countdown.
