## June23th 2015 Calculating Coefficients

Q How do we find out the coefficients that describe the wattage for a particular activity and velocity?

This is easy, since we only need to fit the wattage function $W(v)$ to some sample points of the respective activity.

Here are some typical samples for a walking 75kg person:

$v$ [km/h]$W(v)$ [kcal/h]
4270
6437
9655
12873
151091

Here are some typical samples for a 75kg person riding on a 15kg touring bike (taken from www.kreuzotter.de):

$v$ [km/h]$W(v)$ [kcal/h]
1090
15207
20414
25735
