Book Description
The world is faced with an epidemic of metabolic diseases such as obesity and type 2 diabetes. This is due to changes in dietary habits and the decrease in physical activity. Exercise is usually part of the prescription, the first line of defense, to prevent or treat metabolic disorders. However, we are still learning how and why exercise provides metabolic benefits in human health. This open access volume focuses on the cellular and molecular pathways that link exercise, muscle biology, hormones and metabolism. This will include novel “myokines” that might act as new therapeutic agents in the future.

Book Description
Inhaltsangabe:Abstract: Skeletal muscle is a complex and heterogeneous tissue capable of remarkable adaptation in response to various stimuli such as exercise training. Molecular biology approaches have made a large contribution to our current understanding of how mechanical loading can alter gene expression and muscle protein synthesis rates in skeletal muscle. The steady-state level of a given mRNA is a function of both its rate of synthesis and its rate of degradation, implying that the rate of change in response to a cellular stimulus is dependent on the dynamics of mRNA turnover. Changes in muscle mRNA steady-state levels can be taken as an index of changes in gene expression, constituting currently one of the best described and understood molecular events that underlie muscle plasticity. The discovery of new growth factors involved in the regulation of muscle development provides a better understanding of the molecular mechanisms involved in the adaptation of skeletal muscle to exercise training. Since it has been shown that changes in contractile function can be brought about by switching on one subset and repressing another subset of genes, it was hypothesized that the steady state level of multiple mRNAs (growth factors and metabolic genes) involved in regulatory functions in a muscle which is frequently recruited during exercise is different between endurance trained versus untrained rats. Recent scientific data indicate that myostatin constitutes a limiting factor in normal muscle development playing a crucial role in skeletal muscle hypertrophy. Nevertheless, there are only scarce data so far about the role of myostatin in the exercise-induced skeletal muscle adaptation. The transient changes in regulatory and structural gene expression provide the molecular basis of the adaptability of the skeletal muscle to exercise stimulus. To get an insight into the molecular mechanisms of skeletal muscle adaptation, the main objective of this study was to examine the effect of both the short- and long- term effect of exercise (five day of swimming vs. chronic wheel running) on IGF-I and MSTN (positive and negative skeletal muscle regulators respectively) mRNA contents in male Wistar rats. Potential increase of positive and/or decrease of negative regulators of muscle growth lead to enhanced muscle-progenitor proliferation providing a new perspective in the mechanism of muscle adaptability. It was hypothesized that exercise training could be [...]

Book Description
A comprehensive reference for biochemists, sport nutritionists, exercise physiologists, and graduate students in those disciplines. Provides information on the metabolic processes that take place during exercise, examining in depth the mobilization and utilization of substrates during physical activity. Focuses primarily on the skeletal muscle, but also discusses the roles of the liver and adipose tissue. Annotation copyright by Book News, Inc., Portland, OR

Book Description
The Copenhagen Muscle Research Centre was founded in 1994 with the support of a grant from the Danish National Research Foundation. Among the goals for the Centre is the organization of research symposia, with the aim of bringing a limited number ofintemation ally renowned scientists together to discuss the latest developments and perspectives in their field. The first Copenhagen Muscle Research Centre Conference was held in 1995 and dealt with cardiovascular regulation. The Second Copenhagen Muscle Research Centre Confer ence was held from October 23-26, 1997. The topic of the Symposium was Muscle Metabo lism: Regulation, Exercise, and Diabetes. Seventy invited scientists from all over the world discussed their latest research related to skeletal muscle metabolism. The speakers were asked to expand on their presentations and to write short, but comprehensive, chapters about their given topics. The result is 28 peer-reviewed and edited chapters covering many if not all aspects of muscle energy metabolism related to exercise and diabetes. Emphasis is on regulation of glucose and fatty acid metabolism and the mechanisms regulating their use as fuels for the muscle during exercise. In addition, abnormalities in the regulation of glucose metabolism in the diabetic state are described. However, amino acid and protein metabolism are also thoroughly discussed. We believe that this volume brings an unparralleled, up to date, and comprehensive review of the frontiers in muscle metabolism. Erik A.

Book Description
This unique volume provides a comprehensive review of the biochemistry of exercise. Written by internationally renowned experts, the publication has been completely revised and updated. The present edition follows the new concepts of applied biochemistry which have emerged recently in the scientific literature. Genomics, proteomics, and metabolomics are nowadays common terms used to the elucidation of gene function, expression of proteins and comprehensive analysis of all the metabolites in a tissue. The major steps of biochemistry are considered in active survey in this new 3rd edition of an already acclaimed publication. The book is a valuable source for all exercise biochemists and physiologists, sports physicians, graduate students in physical education and physical therapy, and postgraduate research fellows.

Twenty two, young, healthy individuals participated in three studies aiming to assess the effect of various types of physical activity - acute exercise of moderate intensity and duration, varying intensity, short-term training - on skeletal muscle GLUT-4 gene and protein expression as well as on a range of genes encoding the proteins involved in carbohydrate metabolism in skeletal muscle.

Book Description
In many cases of neuromuscular disorders the physician is faced with a complete lack of therapeutic approaches. This helplessness places the doctor in a position of conflict between his desire to help and his awareness that there is no treatment. In this situation it is tempting to indiscriminately use any procedure that avoids an admission of medical helplessness while satisfying the patient's demand for treatment. Electrical interventions are often used to avoid this situation. Due to the random use of therapeutic approaches it is not known what really happens. Presumptions and biased empirical observations have led to the exten sive use of different forms of electrical stimulation regimes in neuromuscular diseases. Due to this unsatisfactory situation it is necessary to know more about appropriate methods that are being used in particular disorders. The search for a better understanding of nerve-muscle interaction has shown that certain activity patterns can influence muscle. These experi mental results provide a rational basis for a possible therapeutic use of electrical stimulation of nerve and muscle. Previously most research has been conducted in normal tissue, and little is known regarding the re sponses of diseased muscle. In an interdisciplinary approach to this, it is our intention to present the current knowledge about basic principles of electrical stimulation in normal muscle. Before electrical stimulation can be accepted as a therapeutic tool, we felt it necessary to summarize the effects of activity in normal and diseased muscle and nerve.
