[Changes depend on age in electromyogram -- studies about parameter of motor unit action potentials in normal subjects of different age (author's transl)].
In normal subjects of different age groups electromyographically several muscles were examined. The motor unit action potentials were registered and parameters of those were evaluated manually and digitally. For all examined muscles was found an increase in the duration of potentials with the age. The increase was greatest in the younger and older age groups. An interpretation of these findings is given.
