A cognitive challenge when imposed during a low-force isometric contraction will
exacerbate sex-and age-related decreases in force steadiness, but the mechanism is not …

To expose cortical involvement in age-related changes in motor performance, we compared
steadiness (force fluctuations) and fatigability of submaximal isometric contractions with the …

Purpose These studies determined (1) age-and sex-related differences in steadiness of
isometric contractions when high cognitive demand was imposed across a range of forces …

Motor performance and cognitive function both decline with aging. Older adults for example
are usually less steady for a constant-force task than young adults when performing low …

Despite activities of daily living being frequently performed simultaneously with a cognitive
task, motor function is often investigated in isolation, which can hinder the applicability of …

The current study examined the influence of aging on the oscillatory activity of a population
of motor units during rhythmical force production. Previously, it has been shown that aging …

Declines in motor function with advancing age have been attributed to changes occurring at
all levels of the neuromuscular system. However, the impact of aging on the control of …

Aging is accompanied by impaired motor function, but age‐related changes in neural
networks responsible for generating movement are not well understood. We aimed to …

Age-related deterioration of force control is evident on behavioral and neural levels.
Extensive and deliberate practice can decrease these changes. This study focused on …

The purpose of this study was to compare control of force and modulation of agonist muscle
activity of young and older adults when the amount of visual feedback was varied at two …
