Isometric tension values (Po) used in this study.
| MHC-1 | MHC α-cardiac | MHC-2 | MHC-M | |
|---|---|---|---|---|
| isometric tension (N cm−2)a | 22.5 | 5 | 26.3 | 38 |
aAll isometric tension values reported here are from single-fibre studies. Po for MHC-1 (N = 8 fibres) and MCH-2 are from carnivore trunk and limb muscle [64]. The current study did not differentiate among the MHC-2 isoforms; thus, we used an average Po of MHC-2A and MHC-2X (N = 32 fibres). MHC α-cardiac values are from cow (Bos taurus) masseter (N = 25 fibres) [66]. Po for MHC-M (N = 23 fibres) is from carnivore masseter and temporalis muscles [64].
