Abstract
The aim of the studies was to determine how single motor units of different types are used during activities of daily living in man. The extensor digitorum brevis muscle (EDB) was selected for study for technical reasons. The EDB muscle consists of about 50% type I and 50% type II fibers. For details see Grimby and Hannerz 1977; Borg, Grimby and Hannerz 1978; Grimby, Hannerz and Hedman 1981, Grimby 1984.
