Figure 3. Typical original recordings of length (upper panel) and force (lower panel) in a stretch experiment on a maximally Ca²⁺-activated rabbit type IIA fibre.

The following kinetic parameters were determined in order to characterize the time course of stretch induced force transient: t₂, which is the time from beginning of stretch to the lowest force before the onset of delayed force increase; t_½, which is the half-time of the force decay starting 3 ms after beginning of the stretch and ending at t₂; and t₃, which is the time from the beginning of the stretch to the peak of the delayed force increase.
