Fig. 8. (A) Comparison of the model (dotted lines) to individual records of length, force, energetic output and stimulation/activation for an example soleus muscle of a mouse (solid lines) as reported in Barclay (1994). Values are scaled according to average data reported by Barclay and personal communication. (B) Comparison of model (dotted lines) to experimental (solid lines) power and rate of heat and total energy output (power + heat rate) across a range of frequencies. The stimulation rate constants used were ₁=0.045 and ₂=0.045 and V_max=4.0 L_o s^–1.
