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.

Exemple Résolu

A 75 kg cyclist applying 200 N of force at 10 m/s (36 km/h).

  1. Power = 200 x 10 = 2,000 W
  2. Power-to-weight = 2,000 / 75 = 26.67 W/kg
  3. Speed = 10 x 3.6 = 36 km/h
  4. Note: 2000W is a sprint effort; sustained power is much lower
