Skeletal muscle is an extremely heterogeneous tissue composed of a variety of fast and
slow fiber types and subtypes. Moreover, muscle fibers are versatile entities capable of …

abstract Mammalian skeletal muscle is an extremely heterogeneous tissue, composed of a
large variety of fiber types. These fibers, however, are not fixed units but represent highly …

Skeletal muscle is a complex, versatile tissue composed of a large variety of functionally
diverse fiber types. The overall properties of a muscle largely result from a combination of …

In this paper, we describe the effects of voluntary cage wheel exercise on mouse cardiac
and skeletal muscle. Inbred male C57/Bl6 mice (age 8–10 wk; n= 12) ran an average of 4.3 …

In this study, using a high-resolution gel electrophoresis technique, we have characterized
the myosin heavy chain composition in different skeletal muscle of the mouse during …

The deterioration of skeletal muscle with advancing age has long been anecdotally
recognized and has been of scientific interest for more than 150 years. Over the past several …

We tested the hypothesis that denervated muscle fibers account for part of the specific force
(sF o) deficit observed in muscles from old adult (OA) mammals. Whole muscle force (F o) …

With the expansion of the aging population, age-associated sarcopenia (AAS) has become
a severe clinical disease of the elderly and a key challenge for healthy aging. Regrettably …

Mitochondria have diverse functions critical to whole-body metabolic homeostasis.
Endurance training alters mitochondrial activity, but systematic characterization of these …

Sarcopenia is a progressive muscle wasting disorder that severely impacts the quality of life
of elderly individuals. Although the natural aging process primarily causes sarcopenia, it can …
