This is a very interesting discussion in the power/ wattage immunity in golden cheetah. If this is positively used it may create a very new understanding on how valuable power is when combined with physiological feedback and vice verca.
I think this discussion will help to start moving back where we already have been to accept , that there is not one golden tool or idea out there. ( including what we do here with NIRS) As more feedback we can gather as more likely we can work more specific with it.
True there is the limitation of costs and that is what often motivates us to try to get the tool with the possibly most feedback for the money we invest.
One of the tools , whch may be most cost efficient is to go out and have fun to learn and update physiological information as this is what we need to use ideas for physiological stimulation.
here a short section of the inter sting and hopefully great discussion.
Here is why we no longer support TrainingPeaks:
1. We do not endorse the "science" behind the terms.
Despite the furious claims of the originator, there is zero evidence of the validity of TSS, NP, IF, VI, CTL, ATL, TSB and FTP. There are a handful of references to these terms, but no study has ever been published that verifies any of the numerous claims made.
The marketing of these terms has made them popular with amateurs the world over and are considered the lingua-franca of cycling with power. This is because they are promoted in tools such as GC and related. They are not at all widely used by professionals and sports scientists.
