Fig. 8. (A,B) Scatter plots showing the variation in plantaris cycle work as a
function of strain amplitude (A) and peak stress (B) for all six individuals.
(C,D) Plots for work vs strain amplitude (C) and work vs
peak stress (D) for frog 5. Regression lines and partial coefficients of
determination (r2) were calculated in the same manner as
in Fig. 6.
