Protocol
The Chester Step Test, developed by Sykes and Roberts, is a progressive, submaximal step test used in occupational health and safety assessments. Particularly applied in workplace settings, it consists of five cadence stages, with heart rate monitored at each stage to determine test termination. Preparation: A sturdy 30 cm step is prepared. The audio recording is loaded and a heart rate monitor is fitted. The participant is informed that the test will be terminated at any point when the target heart rate is reached. Protocol: The test consists of 5 stages, each lasting 2 minutes: – Stage 1: 15 steps/min – Stage 2: 20 steps/min – Stage 3: 25 steps/min – Stage 4: 30 steps/min – Stage 5: 35 steps/min Heart rate is recorded during the last 30 seconds of each stage. The test ends when target HR (80% of maximum, typically (220 − age) × 0.80) is exceeded or the participant indicates inability to continue. Calculation: VO₂max is estimated using tables based on the HR value and stage number of the last completed stage. Sykes-Roberts regression equations are separated by sex and age. Post-Test: The participant continues slow stepping for a 2–3 minute cool-down. All HR and stage data are reported.Formula
VO₂max estimate: calculated from the Sykes-Roberts table using final-stage HR and stage number
Equipment Required
30 cm step, audio recording (for cadence), heart rate monitor, stopwatch
Normative Values (Age: 20-39)
| Classification | Male | Female |
|---|---|---|
| Excellent | >46 ml/kg/min | >40 ml/kg/min |
| Good | 38-46 ml/kg/min | 32-40 ml/kg/min |
| Average | 30-38 ml/kg/min | 24-32 ml/kg/min |
| Below Average | 22-30 ml/kg/min | 16-24 ml/kg/min |
| Poor | <22 ml/kg/min | <16 ml/kg/min |
Practical Applications
The Chester test is used in occupational health settings for worker fitness assessment, firefighter and law enforcement personnel selection, and cardiopulmonary rehabilitation.Limitations
Although the 30 cm step height is standardized, relative load may vary with participant height. HR-based termination criteria may be misleading for individuals on heart rate-altering medications.Related Tests: Harvard Step Test, Queens College Step Test, 6-Minute Walk Test
