Disclaimer

Treadmill Lab results are general estimates. These estimates are not medical advice, diagnosis, exercise clearance, a training prescription, or a measurement of your body.

Formula limits

Pace and distance depend on the speed and time entered. Calorie and oxygen-demand results use generalized ACSM equations and cannot account for individual movement economy, fitness, age, health, treadmill calibration, handrail use, temperature, or every other factor that changes actual energy use.

The calculator does not infer your gait from belt speed. You select Walking or Running, and that explicit choice controls the equation. The walking equation is intended for speeds up to 6 km/h (approximately 3.73 mph); the running equation is intended for speeds at or above 8 km/h (approximately 4.97 mph). A result outside the selected equation's intended range shows a scope warning rather than silently switching formulas.

The displayed ±10% calorie band is illustrative, not a statistical confidence interval.

Safety

Stop exercise and seek appropriate professional help if you feel unwell. Follow your treadmill manufacturer's limits and safety instructions. Ask a qualified clinician about medical conditions, symptoms, exercise clearance, or individualized advice.
