Fig. 3. Muscle power as a function of strain amplitude for muscles 178 and 179.
Muscle power decreased with increasing strain for both muscles. The blue
filled symbols and solid lines represent the data and regressions for muscle
178. The red broken lines represent the regression lines fitted to the data
for muscle 179. Each line represents a different animal. Mechanical function
for muscle 178 varied with the strain amplitude, while muscle 179 functioned
to absorb energy at all strains. Data for muscle 179 have been previously
published (Ahn and Full, 2002)
and are presented for direct comparison with data for muscle 178.
