Envelope of the sEMG signals during sub-maximal voluntary isometric contractions of biceps muscle. a Envelope of the sEMG signals measured during the 20%, 40% and 80% S V I C b of the biceps muscle in blue. Envelope of the antagonist muscle (triceps) in dashed red. b Boxplots of the 3000 data points (i.e. 3 seconds) measured for each of the SVIC levels shown in A. In blue the boxplots of the biceps sEMG signals and in faded red the boxplots of the antagonist muscle (triceps). Note that the noise level of the sEMG signal during relaxation is also shown
