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] |
---|---|

4 | 270 |

6 | 437 |

9 | 655 |

12 | 873 |

15 | 1091 |

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] |
---|---|

10 | 90 |

15 | 207 |

20 | 414 |

25 | 735 |

30 | 1169 |
