Muscle Quantity Is Not Synonymous With Muscle Quality

Journal of the American Medical Directors Association, 2013
Greater muscle mass can generally produce greater muscle strength. However, whether higher muscle mass is associated with higher muscle quality (muscle strength relative to muscle mass) remains unknown. Furthermore, the nature of this relationship, and how their interaction determines the presence of functional impairments are unknown.

Muscle conditioning and muscle injuries

Medicine & Science in Sports & Exercise, 1990
Empirical and objective data suggest that muscle and connective tissue can undergo adaptations to physical training resulting in greater tissue mass and increased maximum tensile strength. These adaptations are especially apparent as a result of load bearing and resistive training.

Muscle spindles in the mylohyoid muscle of rats

International Journal of Oral and Maxillofacial Surgery, 1992
The mylohyoid muscle has several functions in relation to respiration, deglutition, and phonation, but these functions are not fully understood. The interaction of the mylohyoid nerve and muscle in 25 rats was studied by neurophysiologic and histologic methods.

Muscle glycogenosis

Journal of Inherited Metabolic Disease, 1990
SummaryThis review describes clinical, biochemical and genetic features of the four inborn errors affecting muscle glycogen breakdown, namely deficiencies of phosphorylase, phosphorylase kinase, amylo‐1,6‐glucosidase and acid α‐glucosidase. They are characterized by a wide spectrum of clinical manifestation, affecting age of onset, clinical features ...

Water in normal muscle and muscle with a tumor

Biochimica et Biophysica Acta (BBA) - General Subjects, 1975
The total water content, the amount of non-freezable water, and the Na-+ and K-+ contents in the gastrocnemius muscle of albino mice with and without a solid tumor were determined. The spin-lattice relaxation time (T1) for the water protons in the two kinds of muscle were measured at six resonance frequencies ranging from 4.5 to 60 MHz over the ...

MUSCLE CHANNELOPATHIES

Continuum, 2006
In recent years the term CHANNELOPATHY has been adopted to describe neurological disorders caused by mutations in different ion channel genes. Myopathic channelopathies include two main groups: nondystrophic myotonias and periodic paralyses. This article reviews the clinical features, diagnostic approach, molecular causes, and management of patients ...

Muscle Spindles in the Digastric Muscle of the Rabbit

Journal of Dental Research, 1988
The digastric muscle of the rabbit was studied for the presence of muscle spindles. One of the 19 adult digastric muscles we examined contained in excess of 12 spindles scattered throughout the belly. No spindles were found in the contralateral muscle, or in any of the digastric muscles from other animals. Although jaw depressor muscles of most mammals

Muscle Contraction and Fibrous Muscle Proteins

1952
Publisher Summary This chapter deals with the contraction of different kinds of muscle that show differences with respect to the amount of tension developed, the maximum shortening, the rate of shortening, and the fuel requirement. These differences not only reflect the varying levels of evolutionary development, but also a considerable adaptation to

The Relation of Muscle Biochemistry to Muscle Physiology

Annual Review of Physiology, 1980
During the last several years, the major challenge in the field of muscle contraction has been to develop a detailed theory explaining how muscle develops force and produces work. There is now general agreement that the overall mechanism of muscle contraction involves the sliding of the thick myosin filaments past the thin actin filaments, a process ...

Muscle Filament Structure and Muscle Contraction

Annual Review of Biophysics and Bioengineering, 1975
Research into the mechanism of muscle contraction has reached a very intriguing stage. It now seems likely that all types of muscle may operate in basically the same way. But despite the present detailed knowledge of the molecular arrangements in certain muscles, the precise way in which a muscle generates force is still a mystery. According to the now
