Rusko Test

Objective:

  • To evaluate cardiovascular recovery capacity after a sub-maximal effort.
  • Frequently used to monitor aerobic fitness and fatigue in athletes.

Required Equipment:

  • Stopwatch.
  • Heart rate monitor (to measure heart rate accurately) ❤️.
  • 40 cm step bench (or a stable step).
  • Metronome or an audio rhythm (to regulate the stepping cadence).
  • Result recording sheet.

Protocol:

Rest:

  • The participant remains seated at rest for 5 minutes.
  • Record the Resting Heart Rate (HRrest).

Light Warm-up:

  • Walking or light jogging (2-3 minutes).

Effort Phase (Step Test):

  • Step up and down the bench at a steady cadence for 5 minutes:
  • 24 cycles/minute (meaning 24 full step-ups per minute).
  • The rhythm can be controlled with a metronome or an audio cue.

At the end of the 5 minutes:

  • Immediately measure the Exercise Heart Rate (HRexercise).

Recovery:

  • The participant stands still, calm, without walking.
  • Measure the Heart Rate after 1 minute of recovery (HR1').

Calculations:

  • Compare HRrest, HRexercise, and HR1' to evaluate recovery capacity.

Interpretation of Results:

  • Good recovery = Rapid drop in heart rate after the effort.
  • Poor recovery = Heart rate remains high → a sign of fatigue, overload, or poor fitness.

Example:

ParameterExample Value
HRrest60 bpm
HRexercise (end of 5 min)150 bpm
HR 1 min post-effort90 bpm

The greater the drop in heart rate after 1 minute, the better the recovery.
