Unfortunately equations Ai and Aii in the first part of the Appendix to this Commentary were published incorrectly.
The correct text should read:
The speed values in Fig. 2 were obtained by estimating, for each duration
(t, in s), the maximum sustainable mechanical effort (Wilkie, 1980)
as:
where A is the maximum long-term mechanical work rate (W), B
is the mechanical equivalent of the available energy from anaerobic sources
(J) and τ is the time constant (s) describing the inertia of the system.
As developed by Wilkie, this equation is accurate for durations of 40 s to 10
min. To take into account the decay of the sustainable maximum oxygen
consumption for longer exercise durations (Saltin, 1973), terms A
have been multiplied by:
where the first ratio represents the sustainable proportion of the total
metabolic power.
The author apologises for any inconvenience this may have caused.
