Table 1.

These muscle parameters define the length–tension and force–velocity relationships of contracting muscle of bullfrogs and grasshoppers, and were compiled from previously published data.

parameter	value for bullfrog	value for grasshopper	definition
Fmax	42.7 Nc	13.1 Na	maximum tetanic force
vmax	124.1 mm s−1c	7.0 mm s−1a	maximum contraction velocity
L0	11.2 mmc	4.0 mma	resting length of muscle
tcontraction	100 msc	300 msa	time until maximum in vitro muscle activation
aL	2.08b	2.08b	determines shape of length–tension relationship
bL	−2.89b	−2.89b	determines shape of length–tension relationship
s	−0.75b	−0.75b	determines shape of length–tension relationship
mass	213.9–373.0 gc	1.5–2.0 ga	range of body mass
