Background: Gait speed declines with increasing age, but it is unclear if gait speed
preferentially correlates with leg muscle strength or mass. Objective: We determined the …

Background. We compared the effects of two uniquely different lower extremity power
training interventions on changes in muscle power, physical performance, neuromuscular …

Objectives To assess the relationship between sensorimotor nerve function and incident
mobility disability over 10 years. Design Prospective cohort study with longitudinal analysis …

Background. Muscle power is related to mobility function in older adults, and effective power
production requires rapid neuromuscular activation. Accordingly, this study examines the …

Objectives: To investigate the association between different types of physical activity
behavior and incident mobility limitation in older men and women and to examine whether …

This review examines the influences of physiological aging processes on connective tissue,
joint integrity, flexibility (range of motion [ROM]), and physical functions of older adults …

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 …

Abstract Marcell, TJ, Hawkins, SA, and Wiswell, RA. Leg strength declines with advancing
age despite habitual endurance exercise in active older adults. J Strength Cond Res 28 (2) …

Background. Fatigue is an important early marker of functional decline among older people,
but the mechanisms underlying this association are not fully understood. The purpose of the …

Background and aims Mobility-related fatigue is an important indicator of functional decline
in old age, however, very little is known about fatigue in the oldest old population segment …
