Activity Calorie Calculator
Calculate total daily exercise calories burned across multiple activities
Total energetic cost across walking, gym, and cardio
| Activity | Duration | Intensity (METs) | Calories Burned | % of Exercise |
|---|---|---|---|---|
| Walking / Commute | 30 min | 3.5 METs | 132 kcal | 20% |
| Gym / Resistance | 50 min | 5.0 METs | 315 kcal | 48% |
| Cardio / Sport | 20 min | 8.5 METs | 214 kcal | 32% |
Mathematical Formula & Scientific Methodology
Formula: Cumulative Exercise Activity Thermogenesis (EAT)
Total EAT = ∑ [(MET_i × 3.5 × Weight (kg) × Duration_i) / 200]Sums energy expenditure components of structured exercise activity thermogenesis.
Model Assumptions
- Individual weight is accurate
- Intensity matches standard compendium values
Variables & Standard Units
| Symbol | Physiological Meaning | Unit |
|---|---|---|
| MET_i | Metabolic equivalent of activity i | MET |
| Duration_i | Duration spent on activity i | minutes |
Scientific Limitations
- Trained endurance athletes may exhibit enhanced economy, burning 5-8% fewer calories for a given task
