“…Trials chosen for MFCV 25 estimation were selected on the basis of maximal force. Maximal MFCV was 26 estimated from the two double-differentials over 250ms-windows by means of the 27 cross-correlation technique (Sbriccoli et al 2003;Bazzucchi et al 2005). The cross 28 correlation function technique was used to estimate the time delay between the two 29 signals (i.e., the amount of time shift that must be applied to one signal to minimize 1 the mean square error with the other).…”

“…Integrated EMG (IEMG) or root mean square (RMS) of EMG signals for computing the amplitude has been used widely to estimate the muscle activation or force level [4][5][6]. IEMG and RMS can be simply computed with the values of the EMG data.…”

“…The characteristic of this relationship between strength x EMG is not completely understood. Moritani and DeVries (11) , Woods and Ritchie (18) , Lawrence and De Luca (10) , Narici et al (12) and Sbricolli et al (16), registered a linear correlation between the values of the amplitude of the EMG signal and the isometric strength of muscles such as the biceps brachii, the vastus lateralis, the soleous among others. On the other hand, Wood and Richtie (17) and Lawrence and DeLuca (9) identified a curvilinear relationship to muscles such as the triceps brachii and the deltoid.…”

The objective of this paper was to verify the reliability of the amplitude of the EMG signal of the vastus lateralis muscle (VL) in the right thigh, in different occasions, during maximum and submaximum knee extensors isometric actions. Three people performed the following protocol: execution of 3 maximum voluntary isometric contractions (MVCs) during 3 s each, with later execution of submaximum actions (20, 40, 60 and 80% of the MVC), calculated considering the MVC of the highest torque peak. Each submaximum contraction (SC) lasted 4 s and was kept through a visual feedback (oscilloscope). Between each MVC and among the SC a 2 min gap was given. Parallel to the actions, EMG signal of the VL muscle was obtained through the surface electrodes put on the muscle venter longitudinally to the direction of the fibers. A reference electrode was positioned in the tuberosity of the tibia. To attest the same position among the sampling the site of the electrodes was marked with a pen for retroprojector. The same protocol was performed after 48hs for reliability analysis. Such analysis was made through Pearson correlation, with significance p<0.05. After signal processing and comparison of root mean square values, obtained in the test and re-test, it was found a high correlation among these values (r=0.972, p<0.01). These results suggest the reliability of the EMG signal, which would make its usage available for investigations that aim at comparing its amplitude in acquisitions performed in different occasions.Key-words: electromiography, reliability, isometric actions.
