Estimation of skating power (roller or ice)

To reach a given speed, a skater must be able to produce a sufficient power, equal to the sum of powers required to overcome three types of resistances:
  • Resistance of friction
  • Resistance of the air
  • Resistance of gravity

In the following calculator, an instant speed gives an instant power and a mean speed gives a mean power.
For example, the mean speed of a continuous maximal effort during 7 min approximately (climbing preferably) allows evaluating the Maximum Aerobic Power (MAP).

Weight of the skater: kg
Weight of the equipment: kg (skates, helmet, clothes, etc.)
Speed of the skater: km/h
Speed of the wind: km/h (+ back, - front)
Slope: % (+ ascent, - descent)
Temperature: C
Pressure: mmHg (Torricelli)
Style (Cs): (0.004 to 0.010)
Friction (Cr or Cg): (0.008 to 0.014 or 0.004 to 0.006)
Aerodynamic (SCx): (0.3 to 0.6)

Auxiliaries for calculation:
  • Mean speed
  • Slope
