[Studies of the architecture and functions of human skeletal muscles with the use ultrasonic scanning].
Architecture of m. triceps with the neutral ankle positioning (O degrees) was studied in vivo in essentially healthy male subjects (n = 8) and patients with motor disorders of varying etiology (4 males and 4 females). Ultrasonic scanning produced real-time images of m.gastrocnemius medialis, m. gastrocnemius lateralis and m.soleus both during relaxation (passive state) and isometric effort at 50% of maximal voluntary force (active state). Length, myofiber pinnation angle and muscle thickness were measured.
