PHASE 1 Preparation

  • Ensure the participant is healthy and injury-free.
  • Select a suitable step height: 15, 20, 25, or 30 cm based on fitness level.
  • Fit a Heart Rate Monitor (Chest strap is recommended for accuracy; Apple Watch is also suitable).
  • Calculate 80% Max HR (220 - Age × 0.8) as the safety ceiling.

PHASE 2 The Procedure

  1. Level 1 Start the metronome at 15 steps/min. Step with the beat: Left Up, Right Up, Left Down, Right Down for 2 minutes.
  2. Record Data At the very end of the 2 minutes, record the Heart Rate (BPM) and Rating of Perceived Exertion (RPE).
  3. Check & Increase If HR is below 80% Max HR and RPE is moderate, proceed immediately to Level 2 (20 steps/min).
  4. Repeat Continue increasing the tempo every 2 minutes (Levels 3, 4, 5) until the stop criteria is met.

PHASE 3 Calculation

Input heart rate data. Calculation requires at least 3 sets of heart rates ≤ 80% Max HR.

warning Stop Criteria (Safety)

Terminate the test immediately if:

  • Heart Rate reaches or exceeds 80% of estimated Max HR.
  • RPE (Perceived Exertion) becomes too high (Hard / Very Hard, > 14).
  • The participant cannot maintain the stepping cadence.
  • The participant requests to stop or shows signs of dizziness/distress.

Scientific Assessment of Aerobic Capacity

The Chester Step Test (CST) is a submaximal cardiorespiratory fitness assessment originally developed by Professor Kevin Sykes at the University of Chester. It has been widely adopted for fitness screening and occupational health assessments in populations with high physical demands, including firefighters, offshore workers, and other physically demanding professions.

How it Works

By stepping on a box at increasing speeds (following a metronome), we observe the linear relationship between your heart rate and oxygen uptake (VO2). This allows us to predict your VO2 Max without requiring you to push to total exhaustion.

  • Safety: Lower impact than treadmill tests.
  • Efficiency: Get professional results in 10 minutes.
  • Reliability: Scientifically validated data points.
