Abstract

Objective: To analyze and compare values of median frequency (MF) and root mean square (RMS) in time, to quantify the change in these parameters depending on the installation of muscle fatigue. Methodology: The volunteers wereevaluated by Surface Electromyography (SEMG) and subjected to tests of isometric contractions of biceps brachii and extensor muscles of the fingers, with load percentage of 25% and 75% of its maximum capacity, in two different days, with at least 48 hours. Results: There was an increase of RMS for both muscles in two tests. This increase was more evident during exercise at 75% of maximum load for both biceps and extensor, and there was greater variation in the biceps muscle when compared with the extender.The variation of the FM was negative for both biceps and extensor, and more evident during exercise at 75% of maximum load. When comparing the two muscles the change occurred by increasing the load was a little higher at the biceps muscle. The installation time of fatigue for both muscles was higher in the protocol to 25% of maximum load. Conclusion: The fatigue installationwas directly proportional to the increase of load and the exerciseduration. The biceps brachialshowed higher fatigue than the extensor fingers, even at 25% and 75% of maximum capacity. It also had less tolerance to time, and have fatigued more quickly.
