1. What is Critical Speed/Power?
Critical speed/power - is a mathematical model for predicting the MMSS (maximal metabolic steady state). So critical speed/power, represents the second threshold, and separates zone 2 (the heavy exercise intensity domain) from zone 3 (the severe exercise intensity domain).
Critical speed - is the term used in sports where speed, is used as a measurement of exercise intensity (running, swimming), whereas critical power - is the term used in sports where power, is used as a measurement of exercise intensity (biking, rowing).
However, crittixal speed/power should not be confused with a second term, the - “critical speed/power model”.
The Critical speed/power model suggests that there is a hyperbolic relationship between the duration of an all-out effort and the speed or power you can maintain for it. However this only applies to efforts ranging from 2 to 20 minutes. And the asymptote of the hyperbola is the critical speed/power.
Onother concept to understand is D’ or W’.
D’ - is referred to as “distance-prime”. It determines how steeply the hyperbola curves upwards. D’ is measured in “meters”.
W’ - is referred to as “double-u-prime”. It determines how steeply the hyperbola curves upwards. W’ is measured in kJ (kilojoules).
So the D’/W’ is the curvature of the power–time relationship and it represents the “capacity” available above CP either in meters or kilojoules.
