Table 1. Skeletal muscle fiber preparation characteristics.
Fibers | Length (µm) | Width (µm) | SL (µm) | Passive tension (kN/m2) | Maximal Ca2+-activated tension (kN/m2) |
---|---|---|---|---|---|
Slow-twitch fibers (n = 18) | 1,071 ± 38 | 76 ± 2 | 2.43 ± 0.02 | 0.66 ± 0.09 | 121 ± 6 |
Fast-twitch fibers (n = 9) | 1,104 ± 85 | 92 ± 3 | 2.43 ± 0.04 | 0.25 ± 0.03 | 145 ± 4 |
