Sex differences in motor unit discharge rates at maximal and submaximal levels of force output.
J. Greig Inglis,David A. Gabriel +1 more
TL;DR: Analysis of the sub-set of strength matched males and females suggest that sex differences in MU behaviour may be a result of females needing to generate greater neural drive to achieve fused tetanus.

Abstract: This study evaluated potential sex differences in motor unit (MU) behaviour at maximal and submaximal force outputs. Forty-eight participants, 24 females and 24 males, performed isometric dorsiflex...

TL;DR: Despite males typically exhibiting greater muscle strength and fatigability than females, it remains unclear if there are sex‐based differences in neuromuscular recruitment strategies e.g. recruitment and modulation of motor unit firing rate at normalized forces and during progressive increases in force.
Sex differences in motor unit behaviour: A review.
TL;DR: In this article , a review summarizes the current knowledge on sex differences in motor unit behaviour and potential factors that may contribute to these differences, and concludes that there is an urgent need to gather more data in females and investigate sex differences of motor unit behavior.

TL;DR: In this article , the authors decomposed motor unit (MU) spike trains from the tibialis anterior, medial gastrocnemius (MG), and soleus (SOL) using high-density surface electromyography and blind source separation algorithms.

Sex differences in the detection of motor unit action potentials identified using high-density surface electromyography.
TL;DR: In this article , the authors used high-density electromyography arrays and motor unit decomposition to compare motor unit yield and discharge properties of the tibialis anterior between male and female humans.

The extraction of neural strategies from the surface EMG
TL;DR: The review describes the limitations of techniques used to infer the level of muscle activation, the type of motor unit recruited, the upper limit ofMotor unit recruitment, the average discharge rate, and the degree of synchronization between motor units.

The effects of length and stimulus rate on tension in the isometric cat soleus muscle
P. M. H. Rack,D. R. Westbury +1 more
TL;DR: By subdividing ventral roots and supplying stimulating pulses to different groups of motor units in rotation, smooth contractions of soleus could be obtained with low rates of stimulation.

Changes in single motor unit behaviour contribute to the increase in contraction speed after dynamic training in humans
TL;DR: It is likely that earlier motor unit activation, extra doublets and enhanced maximal firing rate contribute to the increase in the speed of voluntary muscle contraction after dynamic training.

The discharge of impulses in motor nerve fibres: Part II. The frequency of discharge in reflex and voluntary contractions.
E. D. Adrian,D. W. Bronk +1 more
TL;DR: The present investigation has obtained direct records of the discharge in individual motor nerve fibres innervating the diaphragm, and the results seem so definite that it is unnecessary to set out the whole of the evidence which has been brought forward by indirect methods in the past.
