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 …

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 …

A unique characteristic of skeletal muscle is its diversity. This diversity is created by its
design, ie, its fiber composition and the heterogeneity of the individual fibers. Indeed, we …

1. Maximum velocity of shortening (Vmax) and compositions of myosin heavy chain (MHC)
and myosin light chain (MLC) isoforms were determined in single fibres from the soleus or …

The purpose of this review was to examine three issues that limit our understanding of motor
unit physiology:(1) the range and distribution of the innervation ratios in a muscle;(2) the …

of bed rest. J. Appl. Physiol. 82 (1): 182–188, 1997.—Force, electromyographic (EMG) …

Maximum unloaded shortening velocity (V0) and maximum force normalized to cross-
sectional fiber area (specific tension) were determined in 400 single quadriceps muscle …

A kinetic model of the cross-bridge cycle in skeletal muscle is presented with special
reference to the rate limiting steps regulating the peak rate of force development (dP dt) …
