[EMG-force relation during potentiation].
The influence of muscle potentiation due to short-term arbitrary contraction on electromyogram (EMG)-force relationship was studied in men (m. flexor digitorum sublimis). It has been shown that in the majority of subjects the value of smoothed rectified EMG vs force considerably decreased after the development of potentiation. When the subjects were asked to memorize the level of force and reproduce it upon the development of potentiation without the visual feedback they reproduced a higher level of force. EMG in this case did not change considerably. It was concluded that EMG-force relationship depends on the previous muscular activity.
