The $64,000 answer
Because having a robust mathematical description
of an individual’s power-duration relationship provides
quantitative insight re. their unique abilities and paves
the way for other analyses.

Definitions of terms
• Pmax – the maximal power that can be generated for
a very short period of time. Units are W or W/kg.
• Functional reserve capacity (FRC) – the total amount
of work that can be done during continuous exercise
above FTP before fatigue occurs. Units are kJ or J/kg.
• Functional threshold power (FTP) – the highest
power that can be sustained in a quasi-steady-state
for a prolonged period of time. Units are W or W/kg

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.”

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.”

  • 14. 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 Andrew R.

  • 39. 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 Andrew R.
