Hi all,
I got sEMG sginals from different subjects at 30%, 45% and 60% of MVC for a particular muscle. I want to calculate the the RMS values (time parameter) for the data. is it necessary to normalize it?
My point of view is, as the loads were already normalized during exercise (first we determined MVC and then subject was asked to perform at 30%, 45% and 60% of his own MVC), hence we are already getting the normalized values of sEMG signal. The activation level of muscle is already 30%, 45% and 60% for every subject.
while processing on data, should I divide the data (got during submaximal exercise) with the maximum value (got during MVC)? will it not be normalization for the second time, and apparently it have no purpose.
