Fig. 5. Length-force relationships in twitch (A) and tetanus (B) in directly
stimulated muscle. Forces are expressed as values relative to the force at one
muscle length (l0). In A, each symbol shows the data
obtained at three different temperatures; open circles, 4°C
(N=5); filled triangles, 12°C (N=4); open squares,
22°C (N=4). The thick line shows the least-squares regression
curve calculated from the total data in twitch. In B, the data were obtained
from three different preparations all at 4°C. The thin line is the
regression curve obtained from three preparations. The thick line is the same
regression curve as in A.
