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 …

Mammalian skeletal muscle comprises different fiber types, whose identity is first established
during embryonic development by intrinsic myogenic control mechanisms and is later …

This series of reviews focuses on the most important neuromuscular function in many sport
performances, the ability to generate maximal muscular power. Part 1 focuses on the factors …

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 …

Myofibrillar proteins exist as multiple isoforms that derive from multigene (isogene) families.
Additional isoforms, including products of tropomyosin, myosin light chain 1 fast, troponin T …

Contractile and energetic properties of human skeletal muscle have been studied for many
years in vivo in the body. It has been, however, difficult to identify the specific role of muscle …

1. A large population (n= 151) of human skinned skeletal muscle fibres has been studied.
Force‐velocity curves of sixty‐seven fibres were obtained by load‐clamp manoeuvres at 12 …

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 …

The contractile characteristics of three human muscle groups (triceps surae, quadriceps
femoris and triceps brachii) of seven young male subjects were examined. The contractile …

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 …
