It is becoming increasingly apparent that precise knowledge of the anatomical features of muscle, aponeurosis and tendons are necessary for understanding how a muscle-tendon complex generates force and accomplishes length changes. This report presents both anatomical and functional data from the human soleus muscle acquired using magnetic resonance imaging. The results show a strong relationship between the complex three-dimensional structure of the muscle-tendon system and the intramuscular distribution of tissue velocities during in vivo isometric contractions. The proximal region of the muscle is unipennate whereas the mid region has a radially bipennate hemi-cylindrical structure and the distal region is quadripennate. Tissue velocity mapping shows that the highest velocity regions overlay the aponeuroses connected to the Achilles tendon. These are located on the anterior and posterior surfaces of the muscle. The lowest velocities overlay the aponeuroses connected to the origin of the muscle and were generally located intramuscularly.
