Available in PDF, EPUB and Kindle. Book excerpt: The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.

Available in PDF, EPUB and Kindle. Book excerpt: Nervous Regulation of Circulation in Skeletal Muscle covers the proceedings of the 1966 International Symposium on Circulation in Skeletal Muscle, held at Smolenice, Czechoslovakia. This book is organized into five parts compassing 30 chapters, and starts with a survey of the central nervous regulation of skeletal muscle circulation and the role of fluids regulating in the nervous system and muscles of man. The subsequent part describes the pathways of blood, the relations of the agents in circulation to the body, and the factors determining the blood flow in the human body. Other parts highlight the interrelations between blood flow and metabolism. These parts also tackle the effects of plasma osmolality on resistance to blood flow through skeletal muscle and the effects of venous pressure on capacitance alternations in resting skeletal muscle. The final part examines the process of autoregulation in skeletal muscle. This book will be of value to surgeons, neurologists, and allied scientists.

Available in PDF, EPUB and Kindle. Book excerpt: Respiratory Muscle Training: theory and practice is the world’s first book to provide an "everything-you-need-to-know" guide to respiratory muscle training (RMT). Authored by an internationally-acclaimed expert, it is an evidence-based resource, built upon current scientific knowledge, as well as experience at the cutting-edge of respiratory training in a wide range of settings. The aim of the book is to give readers: 1) an introduction to respiratory physiology and exercise physiology, as well as training theory; 2) an understanding of how disease affects the respiratory muscles and the mechanics of breathing; 3) an insight into the disease-specific, evidence-based benefits of RMT; 4) advice on the application of RMT as a standalone treatment, and as part of a rehabilitation programme; and finally, 5) guidance on the application of functional training techniques to RMT. The book is divided into two parts – theory and practice. Part I provides readers with access to the theoretical building blocks that support practice. It explores the evidence base for RMT as well as the different methods of training respiratory muscles and their respective efficacy. Part II guides the reader through the practical implementation of the most widely validated form of RMT, namely inspiratory muscle resistance training. Finally, over 150 "Functional" RMT exercises are described, which incorporate a stability and/or postural challenge – and address specific movements that provoke dyspnoea. Respiratory Muscle Training: theory and practice is supported by a dedicated website (www.physiobreathe.com), which provides access to the latest information on RMT, as well as video clips of all exercises described in the book. Purchasers will also receive a three-month free trial of the Physiotec software platform (via www.physiotec.ca), which allows clinicians to create bespoke training programmes (including video clips) that can be printed or emailed to patients.

Book excerpt: A leading orthopedic surgeon and a top sports chiropractor team up to offer a groundbreaking new approach to remaining injury-free and recovering from injury faster. Muscle injuries are not just for sports superstars anymore. Back, shoulder, hip, and knee problems bedevil more and more people than ever before. Muscle Medicine provides a way to prevent such injuries from happening and to treat them when they do without drugs or surgery. The product of a collaborative effort between two widely recognized authorities on sports injuries, Muscle Medicine relies on cutting-edge medical and therapeutic expertise to deliver what many doctors cannot: explanations of how to maintain good muscle health, how to treat common muscle injuries, such as “Tennis Elbow” and “Cell Phone Neck,” and how to determine when joint surgery is and is not necessary for some common orthopedic problems. By focusing on the health of our muscles, we can prevent many sports injuries from occurring and recover faster from the ones that do, say the coauthors, whose A-list clients have included John McEnroe and Elisabeth Hasselbeck. Featuring more than 100 illustrations that show the basics of muscle mechanics, along with various stretching, strengthening, and self-treatment exercises, Muscle Medicine will help readers enjoy pain-free, active lives no matter what their age or activity level.
Download or read book Application of Muscle Nerve Stimulation in Health and Disease written by Gerta Vrbová and published by Springer Science & Business Media. This book was released on 2008-04-19 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first evidence that electrical changes can cause muscles to contract was p- vided by Galvani (1791). Galvani’s ideas about ‘animal electricity’ were explored during the 19th and 20th century when it was firmly established that ‘electricity’ is one of the most important mechanisms used for communication by the nervous system and muscle. These researches lead to the development of ever more soph- ticated equipment that could either record the electrical changes in nerves and muscles, or elicit functional changes by electrically stimulating these structures. It was indeed the combination of these two methods that elucidated many of the basic principles about the function of the nervous system. Following these exciting findings, it was discovered that electrical stimulation and the functions elicited by it also lead to long-term changes in the properties of nerves and particularly muscles. Recent findings help us to understand the mec- nisms by which activity induced by electrical stimulation can influence mature, fully differentiated cells, in particular muscles, blood vessels and nerves. Electrically elicited activity determines the properties of muscle fibres by activating a sequence of signalling pathways that change the gene expression of the muscle. Thus, elect- cal activity graduated from a simple mechanism that is used to elicit muscle c- traction, to a system that could induce permanent changes in muscles and modify most of its characteristic properties.
