Calories Burned by Exercise Calculator
Calculate energy expenditure across 18 standardized sports and gym activities
Running (10 km/h / 6 mph) for 45 minutes (9.8 METs)
Mathematical Formula & Scientific Methodology
Formula: Compendium MET Equation
Calories = MET × Weight (kg) × [Duration (min) / 60]Calibrated metabolic equivalent values validated through indirect calorimetry.
Model Assumptions
- Sustained active participation without extensive rest gaps
Variables & Standard Units
| Symbol | Physiological Meaning | Unit |
|---|---|---|
| MET | Metabolic Equivalent of Task (Ainsworth et al.) | dimensionless |
| 1 MET | 3.5 ml O2/kg/min = 1 kcal/kg/hour | kcal/kg/hr |
Scientific Limitations
- Individual mechanical efficiency can cause ±10% variance
