Abstract

The fiber type composition of muscle units in the cat diaphragm was examined. As expected, slow-twitch units were composed of type I fibers and fast units were composed of type II fibers. Fast fatigable units were composed of type IIB fibers and fast fatigue resistant units were composed of type IIA fibers. Surprisingly, fast fatigue intermediate units were comprised of both type IIA and IIB fibers.
