Table 3. Muscle architecture per soleus compartment of two human cadaveric soleus muscles measured by microdissection techniques.

The values represent the mean ± SD of all fascicles that were digitised in that compartment.

	Medial-posterior	123	31.4 ± 5.1	19.6 ± 4.7
	Lateral-posterior	68	27.9 ± 7.1	24.2 ± 7.4
Muscle 2	Medial-anterior	90	50.9 ± 4.8	19.9 ± 4.6
	Lateral-anterior	58	46.2 ± 5.0	18.0 ± 4.4
