Immobilization of the rabbit tibialis anterior muscle in a lengthened position causes addition of sarcomeres in series and extra-cellular matrix proliferation.

Abstract

Rabbits were immobilized for 3 weeks with the ankle in plantar flexion, midrange position or dorsal extension (n=15). The left leg was used as control. Sarcomere lengths were measured by laser diffraction in vivo in the tibialis anterior (TA) muscle. Legs immobilized in the midrange position showed coherent diffraction patterns through the range of motion… (More)
