Sarcopenia is a loss of muscle mass and function in the elderly that reduces mobility,
diminishes quality of life, and can lead to fall-related injuries, which require costly …

Dynapenia (pronounced dahy-nuh-pē-nē-a, Greek translation for poverty of strength, power,
or force) is the age-associated loss of muscle strength that is not caused by neurologic or …

A characteristic feature of aged humans and other mammals is the debilitating, progressive
loss of skeletal muscle function and mass that is known as sarcopenia. Age-related muscle …

Biopsy samples were taken from vastus lateralis muscle of seven young (YO, age 30.2±2.2
years), and seven elderly (EL, age 72.7±2.3 years) subjects and two elderly subjects whose …

Biopsy samples were taken from the vastus lateralis of 18-to 84-yr-old male sprinters (n=
91). Fiber-type distribution, cross-sectional area, and myosin heavy chain (MHC) isoform …

With advancing age, skeletal muscle function declines as a result of strength loss. These
strength deficits are largely due to reductions in muscle size (ie, quantity) and its intrinsic …

The purpose of this study was to determine whether there was an age‐related decline in the
isometric and isotonic contractile function of permeabilized slow (MHC I) and fast (MHC IIa) …

The loss of skeletal muscle strength occurs with age, but the reason why there are
differences in rates and magnitude of losses between females and males is not clear. Sex …

Aging is associated with a progressive decline of muscle mass, strength, and quality, a
condition described as sarcopenia of aging. Despite the significance of skeletal muscle …

Sarcopenia and muscle weakness are well-known consequences of aging. The aim of the
present study was to ascertain whether a decrease in fascicle force (Ff) could be accounted …
