Background. In a clinical study evaluating the functioning of mobility-limited elders, muscle
power accounted for more of the variation in function than strength did. There was also …

Background. Functional issues (impairments, functional limitations, and disabilities)
gradually occur with age. Nonetheless, maintaining physical capability may help prevent …

Background. Mobility limitations are prevalent, potentially reversible precursors to mobility
loss that may go undetected in older adults. This study evaluates standardized …

Physical activity is considered crucial in attenuating losses in strength and power associated
with ageing. However, in well-functioning, active older adults the relationship between …

Background Approximately 35% of individuals over age 70 report difficulty with mobility.
Muscle weakness has been demonstrated to be one contributor to mobility limitations in …

Background Weakness is a risk factor for physical limitations and death in older adults
(OAs). We sought to determine whether OAs with clinically meaningful leg extensor …

Objectives Understanding the role of muscle strength as a preventive factor for shorter-term
declines in function may provide further insights into the disabling process. This study …

Background: Muscle mass, strength and fitness play a role in lower-extremity physical
function (LEPF) in older adults; however, the relationships remain inadequately …

Background. Aging is associated with increased risk of reduced mobility. However, data on
muscle components in relation to subjective and objective indicators of disability is limited …

Background and Purpose: It is not known whether short functional performance tests used in
aging research are appropriate for use in healthy older adults. The purpose of this study was …
