Tutorial: Analysis of motor unit discharge characteristics from high-density surface EMG signals

A Del Vecchio, A Holobar, D Falla, F Felici… - Journal of …, 2020 - Elsevier

density surface EMG (HDEMG) decomposition. Since then, the number of studies that use …

Force steadiness: from motor units to voluntary actions

RM Enoka, D Farina - Physiology, 2021 - journals.physiology.org
Voluntary actions are controlled by the synaptic inputs that are shared by pools of spinal
motor neurons. The slow common oscillations in the discharge times of motor units due to …

[HTML][HTML] The knowns and unknowns of neural adaptations to resistance training

J Škarabot, CG Brownstein, A Casolo… - European Journal of …, 2021 - Springer
The initial increases in force production with resistance training are thought to be primarily
underpinned by neural adaptations. This notion is firmly supported by evidence displaying …

Muscles from the same muscle group do not necessarily share common drive: evidence from the human triceps surae

F Hug, A Del Vecchio, S Avrillon… - Journal of applied …, 2021 - journals.physiology.org
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 …

Principles of motor unit physiology evolve with advances in technology

D Farina, F Negro, S Muceli, RM Enoka - Physiology, 2016 - journals.physiology.org
Movements are generated by the coordinated activation of motor units. Recent technological
advances have made it possible to identify the concurrent activity of several tens of motor …

Tracking motor units longitudinally across experimental sessions with high‐density surface electromyography

E Martinez‐Valdes, F Negro, CM Laine… - The Journal of …, 2017 - Wiley Online Library
Key points Classic motor unit (MU) recording and analysis methods do not allow the same
MUs to be tracked across different experimental sessions, and therefore, there is limited …

The role of the neural stimulus in regulating skeletal muscle hypertrophy

C Alix-Fages, A Del Vecchio, E Baz-Valle… - European journal of …, 2022 - Springer
Resistance training is frequently performed with the goal of stimulating muscle hypertrophy.
Due to the key roles motor unit recruitment and mechanical tension play to induce muscle …

Analysis of motor unit spike trains estimated from high-density surface electromyography is highly reliable across operators

F Hug, S Avrillon, A Del Vecchio, A Casolo… - Journal of …, 2021 - Elsevier
There is a growing interest in decomposing high-density surface electromyography
(HDsEMG) into motor unit spike trains to improve knowledge on the neural control of muscle …

Network structure of the human musculoskeletal system shapes neural interactions on multiple time scales

JN Kerkman, A Daffertshofer, LL Gollo… - Science …, 2018 - science.org
Human motor control requires the coordination of muscle activity under the anatomical
constraints imposed by the musculoskeletal system. Interactions within the central nervous …

The forces generated by agonist muscles during isometric contractions arise from motor unit synergies

A Del Vecchio, CM Germer, TM Kinfe… - Journal of …, 2023 - Soc Neuroscience
