Figure 3. Late phases of the isotonic velocity transient at different loads.

A, dependence of the rate of phase 3 (r₃) on T/T₀ in control (black circles) and in 10 mm P_i (green circles). B, relations between force (T, kPa) and shortening velocity during phase 4 in control (black circles) and in 10 mm P_i (green circles). Lines are Hill hyperbolic equations fitted to the data (same colour code as for data). Inset, same relations (experimental data omitted) with force expressed as T/T₀. C, power–force relations calculated from data (symbols) and their fits (lines) in B. Inset, same relations with force expressed as T/T₀. Data are means ± SEM.
