First published in 1994, this book explores the paradigm of muscles as molecular and metabolic machines in which all structures and functions are exquisitely integrated and matched to each other. The analysis begins with a standard reductionist approach-reviewing the integrated machine parts. The key working components of the complete muscle machine are proteins (soluble, organelle, or membrane localized), and a conservative count indicates that today more than 100 such machine parts are known, essentially all occurring as cell specific isoforms. Random assortment of these machine parts or protein isoforms could generate an astronomical number of "muscle machines" and an equally enormous number of muscle fiber types. The question is, why aren't such large numbers ever seen? To attack this problem, the reductionist approach is complemented with an integrationist/adaptational one. Evidence is presented that the more highly specialized the muscle type, the further one moves from the above extreme; in the most highly specialized muscles, typically only one fiber type is found. It is argued that instead of random assortment of isoforms or machine parts, only specific and often unique combinations can work in appropriate fashion. A few established examples of this fundamental principle are reviewed, but emphasis is placed on the fact that we know dreadfully little about why this is so and what kinds of further studies are needed. The issue of why the very large numbers of fiber types theoretically possible are never even approximately realized has never before been addressed. Indeed, it is rarely recognized. Muscles as Molecular and Metabolic Machines is the first work of its kind on the subject.
This is the first book on such topics written specifically for modules in exercise and sport science at final year Hons BSc and taught MSc levels.
Diabetes research on models comprising intact animal tissues, cell cultures and isolated pancreatic islets is essential for understanding the pathogenesis of the disease as well as the mechanisms responsible for the chronic complications ...
How do our muscles produce energy for exercise and what are the underlying biochemical principles involved? These are questions that students need to be able to answer when studying for a number of sport related degrees.
Muscle Metabolism During Exercise
This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service.
This book is intended for professionals who are interested in muscle function, physiology, pathophysiology and well-being, such as therapists, trainers and medical professionals as well as for researchers in the field of muscle physiology.
A comprehensive reference for biochemists, sport nutritionists, exercise physiologists, and graduate students in those disciplines.
This latter point of view, which is commonly termed the August Krogh Principle (Krogh, 1929; see Krebs, 1975) states that, for any question that a physiologist chooses to address, nature provides an ideal study organism (or, ...
