Age-related changes in the basic functional unit of the neuromuscular system, the motor unit,
and its neural inputs have a profound effect on motor function, especially among the …

Abstract Changes in the neuromuscular system affecting the ageing motor unit manifest
structurally as a reduction in motor unit number secondary to motor neuron loss; fibre type …

This review provides a pulmonary-focused description of the age-associated changes in the
integrative physiology of exercise, including how declining lung function plays a role in …

Performance fatigability is characterized as an acute decline in motor performance caused
by an exercise-induced reduction in force or power of the involved muscles. Multiple …

Acute exercise initiates rapid cellular signals, leading to the subsequent activation of
proteins that increase gene transcription. The result is a higher level of mRNA expression …

Fatigue is believed to be a common complaint among older adults; however, multiple
studies of self-reported fatigue across the lifespan have found this may not be the case. To …

Fatigue is an often-neglected symptom but frequently complained of by older people,
leading to the inability to continue functioning at a normal level of activity. Fatigue is …

Background Jump training (JT) can be used to enhance the ability of skeletal muscle to exert
maximal force in as short a time as possible. Despite its usefulness as a method of …

Introduction Hand grip strength has been widely used as a lead measure in geriatric
conditions such as frailty. However, diversity in assessment protocols and methodologies …

Natural adult aging is associated with many functional impairments of the human
neuromuscular system. One of the more observable alterations is the loss of contractile …
