During exercise, there is a progressive reduction in the ability to produce muscle forces.
Processes within the nervous system, as well as within the muscles contribute to this fatigue …

The force exerted by a muscle during a voluntary contraction depends on the number of
motor units recruited for the action and the rates at which they discharge action potentials …

All movements are generated by the activation of motoneurons, and hence their input-output
properties define the final step in processing of all motor commands. A major challenge to …

Muscle fatigue is a temporary decline in the force and power capacity of skeletal muscle
resulting from muscle activity. Because control of muscle is realized at the level of the motor …

The purpose of our review was to compare the distribution of motor unit properties across
human muscles of different sizes and recruitment ranges. Although motor units can be …

Advances in technology have ushered in a new era in the measurement and interpretation
of surface-recorded electromyographic (EMG) signals. These developments have included …

Objective. All motor commands flow through motoneurons, which entrain control of their
innervated muscle fibers, forming a motor unit (MU). Owing to the high fidelity of action …

Persistent inward calcium and sodium currents (IP) activated during motoneuron recruitment
help synaptic inputs maintain self-sustained firing until derecruitment. Here, we estimate the …

Motoneurons are unique in being the only neurons in the CNS whose firing patterns can be
easily recorded in human subjects. This is because of the one-to-one relationship between …

Delayed onset muscle soreness (DOMS) is hypothesized to be caused by glutamate
excitotoxicity-induced acute compression axonopathy of the sensory afferents in the muscle …
