New Findings What is the topic of this review? We review sex differences within
physiological systems implicated in exercise performance; specifically, how they integrate to …

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 …

Biological sex is a primary determinant of athletic performance because of fundamental sex
differences in anatomy and physiology dictated by sex chromosomes and sex hormones …

Modulation of movement velocity is necessary during daily life tasks, work, and sports
activities. However, assessing motor unit behavior during muscle shortening and …

Variability in muscle force is a hallmark of healthy and pathological human behavior.
Predominant theories of sensorimotor control assume 'motor noise'leads to force variability …

Age-related impairments in motor performance are caused by a deterioration in mechanical
and neuromuscular functions, which have been investigated from the macro-level of muscle …

The neuromuscular mechanisms leading to impaired motor performance after mental fatigue
(MF) are not well-understood and little is known of sex-specific differences in the …

Mental fatigue (MF) does not only affect cognitive but also physical performance. This study
aimed to explore the effects of MF on muscle endurance, rate of perceived exertion (RPE) …

The purpose was to identify the variables that can explain the variance in the grooved
pegboard times of older adults categorized as either fast or slow performers. Participants (n …

Nervous system maladaptation is linked to the loss of maximal strength and motor control
with aging. Motor unit discharge rates are a critical determinant of force production; thus …
