Physiological and Pathological Responses to Hypoxia and High Altitude
Author: Rodrigo IturriagaPublisher: Frontiers Media SA

Book Description
The appearance of photosynthetic organisms about 3 billion years ago increased the partial pressure of oxygen (PO2) in the atmosphere and enabled the evolution of organisms that use glucose and oxygen to produce ATP by oxidative phosphorylation. Hypoxia is commonly defined as the reduced availability of oxygen in the tissues produced by different causes, which include reduction of atmospheric PO2 as in high altitude, and secondary to pathological conditions such as sleep breathing and pulmonary disorders, anemia, and cardiovascular alterations leading to inadequate transport, delivery, and exchange of oxygen between capillaries and cells. Nowadays, it has been shown that hypoxia plays an important role in the genesis of several human pathologies including cardiovascular, renal, myocardial and cerebral diseases in fetal, young and adult life. Several mechanisms have evolved to maintain oxygen homeostasis. Certainly, all cells respond and adapt to hypoxia, but only a few of them can detect hypoxia and initiate a cascade of signals intended to produce a functional systemic response. In mammals, oxygen detection mechanisms have been extensively studied in erythropoietin-producing cells, chromaffin cells, bulbar and cortical neurons, pulmonary neuroepithelial cells, smooth muscle cells of pulmonary arteries, and chemoreceptor cells. While the precise mechanism underpinning oxygen, sensing is not completely known several molecular entities have been proposed as possible oxygen sensors (i.e. Hem proteins, ion channels, NADPH oxidase, mitochondrial cytochrome oxidase). Remarkably, cellular adaptation to hypoxia is mediated by the master oxygen-sensitive transcription factor, hypoxia-inducible factor-1, which can induce up-regulation of different genes to cope the cellular effects related to a decrease in oxygen levels. Short-term responses to hypoxia included mainly chemoreceptor-mediated reflex ventilatory and hemodynamic adaptations to manage the low oxygen concentration while more prolonged exposures to hypoxia can elicit more sustained physiological responses including switch from aerobic to anaerobic metabolism, vascularization, and enhancement of blood O2 carrying capacity. The focus of this research topic is to provide an up-to-date vision on the current knowledge on oxygen sensing mechanism, physiological responses to acute or chronic hypoxia and cellular/tissue/organ adaptations to hypoxic environment.
Eating Disorders in Athletes
Author: Joaquin DosilPublisher: John Wiley & Sons
ISBN: 9780470725054
Category : Psychology
Languages : en
Pages : 230
Book Description
This comprehensive, up-to-date book presents the latest research and applied practice to address all of the key issues relating to sport and eating disorders. The book begins by looking at the underlying factors behind the development of disordered eating. It goes on to consider evaluation, diagnosis and treatment across a wide range of sports and assesses the various types of treatment available and the practicalities of implementing treatment programmes. A whole chapter is devoted to the role of the internet, both as a source of information and possible treatment, for athletes with these disorders. The final chapter provides four practical examples and case studies of disordered eating in high-risk sports.

The acute poorly performing sport horse
Author: Arno LindnerPublisher: BRILL
ISBN: 9086866433
Category : Medical
Languages : en
Pages : 192
Book Description
The determination and management of performance-limitation in sport horses is very challenging, especially within a short time period before an important competition. In this book experts disclose their experience on: -What do we know about the poor performance horse? -The gastrointestinal tract: medical, nutritional and surgical considerations. -Could it be the heart? -Could it be the muscles? -Monitoring orthopaedic health in competition horses. -Could it be the foot? -Could it be neurological? -Cases where physiotherapy helped to make a difference. -Could it be respiratory?
Weight Loss
Author: Ignacio Jáuregui LoberaPublisher: BoD – Books on Demand
ISBN: 1789236908
Category : Medical
Languages : en
Pages : 172
Book Description
Epidemiological studies show that weight loss has many health benefits, so different strategies have been explored to lose weight, with health and esthetic reasons being the base of those strategies. Weight loss may be the result of pathologies, so both intentional and unintentional weight loss are different situations, each being a relevant focus of study. Along with that distinction, gender and ethnic topics are also relevant aspects, and different chapters of this book are related to male vs. female topics as well as to cultural differences related to weight loss. Childhood obesity from a parenting style perspective is also developed in this book. Finally, it must be noted that activity is essential to improve body composition and also to keep an ideal weight.
