Muscle fiber types and function

Current Opinion in Rheumatology, 1993
In this review, we address current concepts and recent experimental results that relate to heterogeneity in the physiologic, biochemical, and morphologic properties of mammalian skeletal muscle fibers. Recent data reinforce some of these current concepts while questioning others.

Fiber Typing in Aging Muscle

Exercise and Sport Sciences Reviews, 2014
It is accepted widely that fast-twitch muscle fibers are preferentially impacted in aging muscle, yet we hypothesize that this is not valid when aging muscle atrophy becomes severe. In this review, we summarize the evidence of fiber type-specific effect in aging muscle and the potential confounding roles of fibers coexpressing multiple myosin heavy ...

Muscle Strength and Fiber Typing

Clinics in Sports Medicine, 1984
The authors discuss fiber typing and morphologic changes resulting from training and how these affect athletic performance. Also considered is the concept of strength, its measurement and development, and how strength affects athletic performance, activity, and injury.

Hereditary Continuous Muscle Fiber Activity

Archives of Neurology, 1984
We describe a family with classic features of continuous muscle fiber activity (Isaacs-Mertens syndrome) appearing in an autosomal dominant pattern. Both a mother and her son had muscle stiffness and rigidity in early childhood. Because the mother's condition was not immediately apparent, we recommend a thorough examination of family members.

Continuous muscle fiber activity syndrome

Pediatrics International, 1995
AbstractA 5.5 year old Turkish boy who suffered from progressive muscle stiffness was diagnosed as having continuous muscle fiber activity syndrome. Electromyography showed continuous motor neuron activity at rest and following intravenous injection of diazepam. Peripheral nerve block, spinal and general anesthesia diminished the spontaneous activities.

Muscle Fiber Types of Human Orbicularis Oculi Muscle

Journal of Craniofacial Surgery, 2011
The aim of this study was to elucidate the muscle type of the preseptal, pretarsal, and ciliary parts of the orbicularis oculi muscle in humans using immunostaining. The eyelids of 5 Korean adult cadavers were used (3 male and 2 female cadavers; age range, 50-85 years).

Muscle-fiber characteristics in adult mouse-tongue muscles

Anatomical Science International, 2002
To clarify functions of the mouse-tongue muscles, proteins such as myocin heavy chain (MHC) 2a and MHC-2b, which are isoforms of the fast-twitch fiber type myosin heavy chain, in the lateral margin of the tongue were observed by reverse transcription polymerase chain reaction and immunohistochemical analyses.

Muscle fiber types.

Archives of physical medicine and rehabilitation, 1982
This review describes muscle fiber types based on their histochemical, ultrastructural, biochemical, and physiologic properties. Reportedly the speed of muscle fiber contraction is directly proportional to relative myosin ATPase activity (at pH 9.4) while fatigability relates to relative oxidative capacity. Type I fibers have low ATPase activity (at pH

Muscle fiber splitting in stretch-enlarged avian muscle

Medicine and Science in Sports and Exercise, 1994
This study examined the role of longitudinal fiber splitting in enlarged anterior latissimus dorsi (ALD) muscle of adult quail. Muscle hypertrophy was induced using a model of progressive stretch overload (PSO) (5). After 16 and 28 d of PSO, muscle mass in the stretched ALD muscle increased significantly (P < 0.05) 188% and 294%, respectively, when ...

Fiber Types in Mammalian Skeletal Muscles

Physiological Reviews, 2011
Mammalian skeletal muscle comprises different fiber types, whose identity is first established during embryonic development by intrinsic myogenic control mechanisms and is later modulated by neural and hormonal factors. The relative proportion of the different fiber types varies strikingly between species, and in humans shows significant variability ...
