Understanding Your Result

The calculation generated by this tool provides an evidence-based assessment derived from established physiological and clinical equations. Use this measurement as an educational indicator alongside broader lifestyle variables, including overall dietary quality, resistance training, cardiovascular endurance, and routine medical checkups.

Mathematical Formula & Scientific Methodology

Calories burned is calculated using the Compendium of Physical Activities MET formula: Calories = (MET × 3.5 × Weight in kg / 200) × Duration in minutes.

\text{Calories} = \left(\frac{\text{MET} \times 3.5 \times \text{Weight (kg)}}{200}\right) \times \text{Duration (mins)}

Step-by-Step Example Calculation

For a 70 kg individual running at 6 mph (MET 9.8) for 45 minutes: Calories = (9.8 × 3.5 × 70 / 200) × 45 = (2401 / 200) × 45 = 12.005 × 45 = 540 kcal.

Clinical Limitations & Nuances

Actual calorie expenditure varies with individual fitness efficiency, body composition, ambient temperature, and heart rate response.

Frequently Asked Questions

What does MET mean in exercise science?

MET stands for Metabolic Equivalent of Task. 1 MET represents the energy cost of sitting quietly at rest (approx. 1 kcal/kg/hour or 3.5 ml O2/kg/min).

Why do heavier individuals burn more calories for the same activity?

Carrying more body mass requires more mechanical energy and oxygen consumption to move against gravity, increasing total calorie expenditure.
