Energy Formula:
From: | To: |
Definition: This calculator computes the energy expenditure based on power output and time duration.
Purpose: It helps athletes, coaches, and fitness enthusiasts determine energy output during ergometer (erg) workouts.
The calculator uses the formula:
Where:
Explanation: The power output is multiplied by the time duration to calculate total energy expenditure.
Details: Accurate energy calculation helps in workout planning, performance tracking, and energy system development.
Tips: Enter the power in watts and time in seconds. All values must be > 0.
Q1: What's a typical power output for rowing?
A: Competitive rowers might maintain 200-300W for long pieces, with higher outputs for sprints.
Q2: How does this relate to calories burned?
A: 1 kcal ≈ 4184 J. The erg's calorie display uses a different formula accounting for human efficiency.
Q3: Why measure in Joules?
A: Joules provide a direct physics-based measurement of work done, independent of human efficiency factors.
Q4: Can I use this for cycling ergometers?
A: Yes, the formula applies to any activity where power output is measured in watts.
Q5: How accurate is this calculation?
A: Mathematically precise for the given inputs, but actual physiological energy expenditure may vary.
