The New Power Duration Model in WKO4 - Part 4

  1. 1. The New Power-Duration Model in WKO4 November 26, 2013 | Andrew R. Coggan, Ph.D.
  2. 2. The $64,000 question Why attempt to mathematically model the powerduration relationship? Andrew R.

  3. 3. 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.

  6. 6. 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 Andrew R.

  14. 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. 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.
