Initial values of force and electromyographic (EMG) parameters.
| Exp1 | Exp2 | Exp3 | |
|---|---|---|---|
| Superimposed twitch, N | 3.0 ± 1.3 | 3.3 ± 1.3 | 4.8 ± 1.3 |
| M-wave amplitude, mV | 1.6 ± 1.5 | 1.5 ± 1.5 | 3.9 ± 1.5 |
| M-wave latency, ms | 6.7 ± 1.1 | 6.5 ± 0.5 | 6.6 ± 0.4 |
| Tetanic force, N | 59.7 ± 17.8 | 62.2 ± 18.8 | 52.9 ± 13.8 |
| Tetanic HRT, ms | 88 ± 13 | 82 ± 7 | 81 ± 9 |
| Potentiated twitch, N | 9.2 ± 2.7 | 10.7 ± 2.9 | 10.5 ± 3.0 |
HRT = half relaxation time. Data are expressed as mean ± SD; n = 14 in Exp1, 8 in Exp2, and 6 in Exp3.
