Incremental Shuttle Walk Test VO2 Peak Calculator

Estimate peak VO2 from incremental shuttle walk test distance for COPD and ILD patients. VO2 peak (mL/kg/min) = 4.19 + (0.025 x ISWT metres).

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Estimate peak VO2 from incremental shuttle walk test distance for COPD and ILD patients. VO2 peak (mL/kg/min) = 4.19 + (0.025 x ISWT metres)

Each component has a specific meaning:

  • Incremental shuttle walk test distance — The incremental shuttle walk test distance recorded for the scenario being assessed.

Note: Interpret the iswt vo2 peak result against the thresholds and context described above.

How to Use

Enter the incremental shuttle walk test distance for the scenario you are assessing. Estimate peak VO2 from incremental shuttle walk test distance for COPD and ILD patients. VO2 peak (mL/kg/min) = 4.19 + (0.025 x ISWT metres). Use the iswt vo2 peak result to inform your calculation.
