The aging process leads to adverse changes in body composition (increases in fat mass
and decreases in skeletal muscle mass), declines in physical function (PF), and ultimately …

Introduction Although decline in muscle mass and quality and resulting declines in muscle
strength are associated with aging, more research is needed in general populations to …

The aging process results in several physiological impairments that, in turn, may predispose
older individuals to a series of restrictions on their functional capacity. These impairments …

Objective This study aims to determine the sex-specific relationships of physical activity,
body composition, and muscle quality with lower-extremity physical function in older men …

Muscle quality (the ratio of strength to lean muscle mass) might be a better indicator of
muscle function than strength alone. Differences in muscle quality index (MQI) between …

Objective Poor physical function performance is associated with risks for disability in late life;
however, determinants of physical function are not well characterized in middle-aged …

Objectives To investigate the impact of body mass index (BMI)(normal weight, overweight,
obese) on the relationship between muscle quality (MQ) and physical function in community …

Objective To compare the predictive performance of five handgrip strengths for
cardiovascular disease (CVD) risk factors. Methods A total of 804 Chinese middle-aged …

Objectives The aim of this study was to compare muscle quality (MQ) between
octogenarians classified as non-fallers, fallers and recurrent fallers and identify confounding …

Purpose The age-related decline in physical function is ameliorated by physical activity;
however, less is known about changes in physical function in active vs. inactive older …
