These works are protected by copyright laws and treaties around the world. All such rights are reserved. Benefits of the critical power model “... the critical power concept is useful for two reasons. One, it provides a very good conceptual framework for understanding the most basic factors determining exercise performance/power output (i.e., anaerobic and aerobic energy production), and how the contribution of each varies as a function of time. Two, actually measuring critical power and W’ is well within the capacity of anyone who owns a power meter (and understands a little bit about math), and thus provides a means of quantifying changes in fitness beyond just even "I was able to sustain X watts for Y seconds.” - Yours truly, post to the wattage list on 2/11/2002

Modeling adaption instead of stress/strain “(That is why) it is TSS (training stress score) and not TPS (training performance score).” – Yours truly, post to the the wattage list on 4/30/2005 “XXXX had it right when he indicated that TSS is merely a measure of the overall training load/stress, and in and of itself is *not* a predictor of (aerobic) performance. At least in theory, it is possible to derive a metric that would more directly predict, e.g., changes in functional threshold power, but this would entail more than just ignoring the additional strain resulting from very high intensity exercise... it would require discounting that strain relative to that encountered at lower intensities.” – Yours truly, post to the the wattage list on 9/26/2005
