Background: The association between exercise and muscle build-up is a long-run
connection. Whereas limited physical activity doesn't do well with muscle build-up. But how …

Background Skeletal muscle energetics decline with age, and physical activity (PA) has
been shown to counteract these declines in older adults. Yet, many studies were based on …

Objective To determine whether physical activity is associated with lower limb muscle size
and strength within the general population. Data Sources Six databases were systematically …

Advancing age is associated with a decline in the strength of the skeletal muscles, including
those of respiration. Respiratory muscles can be strengthened with nonrespiratory activities …

The construct of sarcopenia is still discussed with regard to best appropriate measures of
muscle volume and muscle function. The aim of this post-hoc analysis of a cross-sectional …

Background Several studies conducted in a laboratory-related environment have shown that
exercise is associated with increased muscle quality in older adults. The aim of the present …

Objective: To explore the relationship of physical activity and sedentary leisure time with
muscle mass, strength, and quality in Chinese adults. Methods: Based on the second …

[Purpose] Handgrip strength is a surrogate indicator for assessing disease-related and age-
related skeletal muscle loss. Clinical utility as such a surrogate can be at least partially …

Background Studies in mice have suggested that sarcopenic animals may have atrophic
diaphragmatic muscles; however, to date, no clinical studies are available. Aims To …

Background: Using data from a multiethnic cohort, the authors tested associations of multiple
types and intensities of physical activity (PA) with abdominal muscle area and density …
