Effect of separating a slow falling component from the force rise after ramp–restretch
| Period fitted | No. of exponentials | Single rise kr1 (s−1)† | Slow rise krs (s−1) | Fast rise krf (s−1) | Slow fall ks (s−1) | Overshoot (%Po) | Fall/rise: amplitude ratio | Fast amplitude/total rise (A′f)† | n* (Records, Fibres) |
|---|---|---|---|---|---|---|---|---|---|
| Rise to plateau | 1 | 9.1 ± 0.2 | — | — | — | 9 ± 1 | — | — | 45, 15 |
| Rise to plateau | 2 | 6.8 ± 0.2 | — | — | 0.8 ± 0.10 | 9 ± 1 | 0.62 | — | 44, 15 |
| and slow fall | 3 | — | 3 ± 0.3 | 10.7 ± 0.6 | 0.4 ± 0.05 | 17 ± 0.4 | 0.40 | 0.7 | 18, 7 |
Symbols are as in Table 1, and in addition ks = rate constant of the slow falling component. For all records, single, double- and triple-exponential fits were attempted, but in some cases two and/or three components could not be resolved (see Methods).
†
The high A′f value of 0.7 increases kr1 after removal of the slow fall (cf. Table 1).
