Table 1 The difference in tensile force levels and corresponding muscle stiffness in vitro and in vivo (N/m).
| Descriptive statistics – stiffness for the different tensile force levels (mean±SD) | ||||||
|---|---|---|---|---|---|---|
| Experiment I (in vitro) | 0 N | 2 N | 4 N | 6 N | 8 N | 10 N |
| 284.17±25.25 | 287.17±27.67 | 293.67±37.73 | 319.17±28.36 | 367.83±47.46 | 431.33±61.73 | |
| Experiment II (in vivo) | Rest | 10% of MVC | 20% of MVC | 30% of MVC | 40% of MVC | 50% of MVC |
| 186.21±17.09 | 282.97±42.64 | 324.03±43.27 | 381.42±70.35 | 435.48±84.56 | 472.55±80.23 | |
| SD – standard deviation; MVC – maximal voluntary contraction. | ||||||
