title: [Age dependency of muscular action potential duration in the normal human electromyography (author's transl)].
abstract: The medium duration of muscular action potential in both the m. quadriceps and m. gastrocnemius of 188 subjects with normal neurological status between the ages of 15 and 70 were measured. Following results were found: 1. The duration of action potential in the m. quadriceps shows an increase from the age of 15 to 40, beyond which only a partial non-significant increase occurs. 2. The duration of action potential in the m. gastrocnemius also shows an increase up to the age of 40, after which no further increase occurs.
