Stair Climbing Calories Calculator
Calculate energy expenditure on stairmaster machines or outdoor stairs
30 minutes of continuous vertical stepping at 8.8 METs
Mathematical Formula & Scientific Methodology
Formula: Vertical Stair Locomotion MET Standard
Calories = MET × Body Mass (kg) × (Duration / 60)Overcoming gravity vertically requires substantial recruitment of gluteus maximus, quadriceps, and calf muscle fibers.
Model Assumptions
- No leaning with forearms resting heavily on machine handrails
Variables & Standard Units
| Symbol | Physiological Meaning | Unit |
|---|---|---|
| 8.8 MET | Continuous vertical climbing against gravity | dimensionless |
Scientific Limitations
- Holding onto the handles tightly can reduce effective caloric burn by up to 20-30%
