Critical Power

Important

  • NEW in 2.0

  • NEW in 2.4 Find Empty Tank Efforts (and calculate session specific critical power) during data import and updates

  • NEW in 2.6 Added Running Critical Power Calculator

The default calculation of term:Critical Power which occurs post data loading is based on the OMNI model over a time span of three months and uses a large number of data samples from your power history.

The Critical Power Calculator also uses the OMNI model but allows you to choose your own time span, power type, and/or manually enter power values for a selected number of intervals. Access the calculator for cycling or running from the Settings –> Critical Power menu item.

Note

  • Critical Power parameters (term:critical power<Critical Power>, Anaerobic Work Capacity, and max power) are calculated during data import

  • If a session has its power data excluded or session is deleted then the term:critical power<Critical Power> for affected sessions will be updated

  • Empty Tank Efforts (efforts for which W’ Balance would be negative) are found during data import and on updates

  • A session specific term:critical power<Critical Power> is calculated (if possible) for Empty Tank Efforts and is then displayed on Session Summary, Session Chart, Best Power Chart, and FTP Estimates Chart
