Background Aging is often associated with changes in the musculoskeletal system,
peripheral and central nervous system. These age-related changes often result in mobility …

Aging is accompanied by a progressive loss of skeletal muscle mass and strength, leading
to the loss of functional capacity and an increased risk of developing chronic metabolic …

Flexibility refers to the intrinsic properties of body tissues that determine maximal joint range
of motion without causing injury. For many years, flexibility has been classified by the …

Measuring lower body strength is critical in evaluating the functional performance of older
adults. The purpose of this study was to assess the test-retest reliability and the criterion …

Preventing or delaying the onset of physical frailty is an increasingly important goal because
more individuals are living well into their 8th and 9th decades. We describe the development …

This book provides an overview of human development and includes the relationship
between motor development and cognitive and social development. It explores factors …

OBJECTIVES: To determine whether calf circumference (CC), related to appendicular
skeletal muscle mass, can be used as a measure of sarcopenia and is related to physical …

OBJECTIVES: The purpose of this study was to assess the influence of leg power and leg
strength on the physical performance of community‐dwelling mobility‐limited older people …

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 The recovery of quadriceps muscle force and function after total knee
arthroplasty (TKA) is suboptimal, which predisposes patients to disability with increasing …
