Contractile properties and myosin phenotype of single motor units from neonatal rats.

The American journal of physiology - 1 Apr 1994

Nelson A G, Thompson W J

Abstract excerpt

The unloaded shortening velocity (Vus), twitch time to peak force (TTP), and myosin heavy chain (MHC) composition of motor units from soleus muscles of neonatal rats (7-8 and 16-18 days) were compared. The Vus range was from 2.2 to 7.1 fiber lengths (fl).s-1 and was unchanged from 7-8 to 16-18 days. TTP shifted from 7-8 (range, 66-120) to 16-18 days (range, 41-95). MHC-specific antibody staining of motor units...
