Normalized Power (NP) is calculated starting from a power stream as a function of time. Then, from it and your FTP, it can deduce a relative intensity or intensity factor which combined to the duration yields the training load, also called training stress score. It will first calculate a normalized pace or power for your activity. Refer to for more details.įrom this FTP and your actual output level during the activity, 3record can calculate the metrics below introduced by Coggan in. In order to know your FTP, you have to know the constant level you can maintain for 1 hour (which is your FTP by definition) or you can test it on 20 minutes and correct the value obtained by dividing it by 1.05 (as the duration is shorter, your output is about 5% higher). This should in theory match more or less the activity intensity at which you are at your lactate threshold (LT). FTP is defined as the pace (for swim and run) or the power (bike or other) you can keep constant on an effort of about an hour. To normalize the difficulty of any activity against your abilities, 3record uses the functional threshold pace or power (FTP). 3record definitions are conceptually equivalent but may slightly differ in implementation details NP also sometimes refer to Normalized Pace (called Normalized Graded Pace in TrainingPeaks or Grade Adjusted Pace in Strava). Note: NP / Normalized Power, IF / Intensity Factor, TSS / Training Stress Score are claimed trademarks by Peaksware LLC and were first used commercially in their WKO+ software, even though their definitions where discussed by Allen and other on the Wattage group ( ) before the creation of this software.

Anyway…I could talk about it for a long time, but i’ll stop now, but keep saving all that data…and let me know when I can get some muscle biopsies from you. Cycling is also awesome b/c so many cyclists are data nerds and have all of these files (and it’s way easier to get power measurements as opposed to swimming or running).
Cycling is really interesting in this perspective b/c nearly all cyclists are endurance athletes, but some excel at TT’s, others at climbing, and others in sprints, so it’d be neat to see how the individual power curve changes between specialists. Theoretically, there should be 3 distinct regions on a power curve like the one you have displayed…one for each energy system used by the muscle (if you care about ex phys type stuff those are CPK, glycolysis, oxidative phos.).
