Table 1.
Species comparison of muscle properties from in vitro preparations. P0 is the maximum muscle force produced during in vitro preparation; Vmax is the maximum muscle shortening velocity (means ± s.e.m.).
| species | P0 (N cm−2) | Vmax (l s−1) | muscle-mass-specific peak power (W kg−1) | % leg muscle | body-mass-specific peak power (W kg−1) |
