Stroke Rate

The Stroke Rate or Cadence is a common metric in Kayaking. It is measured in Strokes per Minute and can be reported and graphed using the appropriate Info Cell.

KayakNav enables the accelerometer and calculates Stroke Rate only when the Info Cell is displayed. This helps reduce battery consumption when the feature is not being used. Internally KayakNav samples the accelerometer 50 times per second and uses a combination of auto-correlation and a digital phase-locked loop to extract the paddle force profile, power and energy. In a later release (after 2.5), the force profile and other related data for each stroke will be made available in a graphical Info Cell.
