All values are means ± SE. Power was measured under small amplitude conditions, 0.125% muscle length; fmax is the frequency at which maximum power was produced. The rates of phase 2, 3, and 4, r2, r3, and r4, respectively, of the tension transients following stretch are shown. Superscript letters indicate statistical differences between the four sets of fibers based on one-way ANOVA with Holm-Sidak pairwise multiple comparisons, P < 0.05. DS = Drosophila fibers bathed in Swank solutions; DR = Drosophila fibers bathed in Reedy solutions; LS = Lethocerus fibers bathed in Swank solutions; LR = Lethocerus fibers bathed in Reedy solutions.
