Figure 6. The 95 % confidence limits (Kn) for the estimation of the initial rate of change of [PCr] (d[PCr]/dt) using the initial slope estimated from data with a superimposed noise function at different levels of work.
The lines for K1 give the confidence of d[PCr]/dt estimation from a single data sample with a s.d. of 1.5 %Δ. K2 to K4 show the improvement of estimation as successive like bouts are included in the average. The estimation also improves as the steady-state amplitude of response is increased.
