Definition of the method
Normalization to a standardized submaximal task (i.e., it will not elicit the maximum voluntary activation of a muscle). May or may not be task specific. This method includes:
- Submaximal isometric voluntary contraction: The peak EMG or mean EMG amplitude from a submaximal isometric/ dynamic voluntary contraction against a relative or absolute resistance (e.g., holding a weight with force applied through a pulley or against gravity), in a standardized body position/muscle length.
This method includes:
- Normalizing to a standardized submaximal task may enable comparison between tasks. However, the interpretation of the EMG amplitude may differ between participants when normalizing to a standardized submaximal task. Unlike MVC normalization, there is no clear indication of how to interpret the reference value. Further, it doesn’t account for potential differences in muscle length or contraction type between tasks.
