Tutorial: Analysis of motor unit discharge characteristics from high-density surface EMG signals
Recent work demonstrated that it is possible to identify motor unit discharge times from high-
density surface EMG (HDEMG) decomposition. Since then, the number of studies that use …

The increase in muscle force after 4 weeks of strength training is mediated by adaptations in motor unit recruitment and rate coding
Key points Previous studies have indicated that several weeks of strength training is
sufficient to elicit significant adaptations in the neural drive sent to the muscles. There are …

You are as fast as your motor neurons: speed of recruitment and maximal discharge of motor neurons determine the maximal rate of force development in humans
Key points We propose and validate a method for accurately identifying the activity of
populations of motor neurons during contractions at maximal rate of force development in …

Muscles from the same muscle group do not necessarily share common drive: evidence from the human triceps surae
It has been proposed that movements are produced through groups of muscles, or motor
modules, activated by common neural commands. However, the neural origin of motor …
