Asylums: Essays on the Social Situation of Mental Patients and Other Inmates is a 1961 book by sociologist Erving Goffman.
Vmax is equal to the product of the catalyst rate constant (kcat) and the concentration of the enzyme. The Michaelis-Menten equation can then be rewritten as V= Kcat [Enzyme] [S] / (Km + [S]). Kcat is equal to K2, and it measures the number of substrate molecules turned over by enzyme per second.
So, in summary, Critical Power represents a very useful physiological parameter, higher than Lactate Threshold but lower than VO2max. Further, it is highly correlated with both of these measures as well as being highly correlated with endurance performance capacity.
