Advanced Power Metrics for V650
Applies to: V650
In the V650 1.5.4 firmware release, the list of available training view items on the V650 grew to include the following advanced power metrics: NORMALIZED POWER® (NP®), INTENSITY FACTOR® (IF®) and TRAINING STRESS SCORE® (TSS®).
- NORMALIZED POWER (NP) provides an evaluation of training intensity. It provides a better measure of the true physiological demands of a given training session.
- INTENSITY FACTOR (IF) is simply the ratio of the normalized power to your threshold power. IF therefore provides a valid and convenient way of comparing the relative intensity of a training session or race either within or between riders, taking into account changes or differences in threshold power.
- TRAINING STRESS SCORE (TSS) quantifies the overall training load based on your power data. Please note that Polar training load and TRAINING STRESS SCORE cannot be compared. They are two different approaches.
To add these new power metrics to the training views of your V650, go to Settings > Sport profiles and choose the profile you want to edit, and then choose Training views. See Sport profile settings (eManual) for detailed instructions on customizing the training views.
Further information on NP, IF and TSS is available on TrainingPeaks' blog.
