Ratio of peak changes in stress (Δσ_{0.5 Hz}/Δσ_{0.01 Hz} ), crimp frequency (Δf_{crimp, 0.5 Hz}/Δf_{crimp, 0.01 Hz} ) and mean intensity (ΔI_{mean, 0.5 Hz}/ΔI_{mean, 0.01 Hz} ) for the (a–c) 1^st and (d–f) 10^th cycles. Values significantly different than 1 indicate that the parameter was rate-dependent. While Δσ_{0.5 Hz}/Δσ_{0.01 Hz} and ΔI_{mean, 0.5 Hz}/ΔI_{mean, 0.01 Hz} were different than 1 (i.e., changes in stress and mean intensity were rate-dependent) in both the 1^st and 10^th cycles, Δf_{crimp, 0.5 Hz}/Δf_{crimp, 0.01 Hz} was higher than 1 in the 1^st cycle but not in the steady-state.
