[Changes in the global electromyogram during static exercise; effect of age].
In normal man, the EMG changes in forearm muscles holding a tension of 30% maximal voluntary strength for 5 minutes are: (1) an increase of integrated EMG, (2) a slight decrease of the median frequency of the EMG power spectrum. These changes are largely reduced with age.
