Power Output vs Applied Force
Mechanical Power Output
Power is the rate of doing work. In cycling and rowing, it is the product of the force applied and the velocity of movement.
Formula
Power (W) = Force (N) x Velocity (m/s)
The power-to-weight ratio (W/kg) is the most important metric for climbing cyclists. Professional cyclists sustain 5-6 W/kg for an hour; recreational riders typically manage 2-3 W/kg.
Example Calculation
A 75 kg cyclist applying 200 N of force at 10 m/s (36 km/h).
- 01Power = 200 x 10 = 2,000 W
- 02Power-to-weight = 2,000 / 75 = 26.67 W/kg
- 03Speed = 10 x 3.6 = 36 km/h
- 04Note: 2000W is a sprint effort; sustained power is much lower
