Download or read book Energetics of Muscular Exercise written by Guido Ferretti and published by Springer. This book was released on 2015-03-25 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the maximal power and capacity of the three major biochemical pathways - aerobic (oxygen consumption), anaerobic lactic (muscle lactate accumulation in absence of oxygen consumption), and anaerobic alactic (phosphocreatine hydrolysis) metabolism - as well as the factors that limit them. It also discusses the metabolic and cardio-pulmonary mechanisms of the dynamic response to exercise. The way and extent to which the power and capacity of the three major energy metabolisms are affected under a number of different conditions, such as training, hypoxia and microgravity, are also described.
Download or read book High Intensity Exercise in Hypoxia Beneficial Aspects and Potential Drawbacks written by Olivier Girard and published by Frontiers Media SA. This book was released on 2018-01-25 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past, ‘traditional’ moderate-intensity continuous training (60-75% peak heart rate) was the type of physical activity most frequently recommended for both athletes and clinical populations (cf. American College of Sports Medicine guidelines). However, growing evidence indicates that high-intensity interval training (80-100% peak heart rate) could actually be associated with larger cardiorespiratory fitness and metabolic function benefits and, thereby, physical performance gains for athletes. Similarly, recent data in obese and hypertensive individuals indicate that various mechanisms – further improvement in endothelial function, reductions in sympathetic neural activity, or in arterial stiffness – might be involved in the larger cardiovascular protective effects associated with training at high exercise intensities. Concerning hypoxic training, similar trends have been observed from ‘traditional’ prolonged altitude sojourns (‘Live High Train High’ or ‘Live High Train Low’), which result in increased hemoglobin mass and blood carrying capacity. Recent innovative ‘Live Low Train High’ methods (‘Resistance Training in Hypoxia’ or ‘Repeated Sprint Training in Hypoxia’) have resulted in peripheral adaptations, such as hypertrophy or delay in muscle fatigue. Other interventions inducing peripheral hypoxia, such as vascular occlusion during endurance/resistance training or remote ischemic preconditioning (i.e. succession of ischemia/reperfusion episodes), have been proposed as methods for improving subsequent exercise performance or altitude tolerance (e.g. reduced severity of acute-mountain sickness symptoms). Postulated mechanisms behind these metabolic, neuro-humoral, hemodynamics, and systemic adaptations include stimulation of nitric oxide synthase, increase in anti-oxidant enzymes, and down-regulation of pro-inflammatory cytokines, although the amount of evidence is not yet significant enough. Improved O2 delivery/utilization conferred by hypoxic training interventions might also be effective in preventing and treating cardiovascular diseases, as well as contributing to improve exercise tolerance and health status of patients. For example, in obese subjects, combining exercise with hypoxic exposure enhances the negative energy balance, which further reduces weight and improves cardio-metabolic health. In hypertensive patients, the larger lowering of blood pressure through the endothelial nitric oxide synthase pathway and the associated compensatory vasodilation is taken to reflect the superiority of exercising in hypoxia compared to normoxia. A hypoxic stimulus, in addition to exercise at high vs. moderate intensity, has the potential to further ameliorate various aspects of the vascular function, as observed in healthy populations. This may have clinical implications for the reduction of cardiovascular risks. Key open questions are therefore of interest for patients suffering from chronic vascular or cellular hypoxia (e.g. work-rest or ischemia/reperfusion intermittent pattern; exercise intensity; hypoxic severity and exposure duration; type of hypoxia (normobaric vs. hypobaric); health risks; magnitude and maintenance of the benefits). Outside any potential beneficial effects of exercising in O2-deprived environments, there may also be long-term adverse consequences of chronic intermittent severe hypoxia. Sleep apnea syndrome, for instance, leads to oxidative stress and the production of reactive oxygen species, and ultimately systemic inflammation. Postulated pathophysiological changes associated with intermittent hypoxic exposure include alteration in baroreflex activity, increase in pulmonary arterial pressure and hematocrit, changes in heart structure and function, and an alteration in endothelial-dependent vasodilation in cerebral and muscular arteries. There is a need to explore the combination of exercising in hypoxia and association of hypertension, developmental defects, neuro-pathological and neuro-cognitive deficits, enhanced susceptibility to oxidative injury, and possibly increased myocardial and cerebral infarction in individuals sensitive to hypoxic stress. The aim of this Research Topic is to shed more light on the transcriptional, vascular, hemodynamics, neuro-humoral, and systemic consequences of training at high intensities under various hypoxic conditions.

Download or read book EMQs in Clinical Medicine written by Irfan Syed and published by CRC Press. This book was released on 2011-08-26 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: EMQs are a popular method of assessing how broad a knowledge of medicine an undergraduate has acquired. They can, however, be difficult to prepare for, and the best way to build understanding and confidence is with practice. Presenting 100 key EMQs covering the core areas of medicine and surgery, care had been taken by the authors to structure the questions and answers so that they reflect accurately the themes uncountered during study and, specifically, in final exams. Each subject covered is accompanied by a revision section which summarises key points and cross references them to other questions for revision purposes. Questions related to pharmacology, an area which many students find particularly challenging, are threaded throughout the book where relevant, mirroring the integrated teaching methods common to most medical schools. The second edition of EMQs in Clinical Medicine has been thoroughly revised and updated to reflect medical developments, while retaining the clear and comprehensive approach and popular revision boxes of its predecessor. The authors' first-hand experience of EMQ-based examinations, and awareness of the importance of reliable and accurate revision guides to medical students, ensure EMQs in Clinical Medicine remains and invaluable resource for all medical students undertaking the clinical part of their training, and an ideal companion during finals preparation.

Download or read book A Glossary of Anesthesia and Related Terminology written by Sanford L. Klein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this text catches the specialty of anesthesia at what will probably prove to be the apex of its influence and recognition amongst the specialties of medicine. The scientific basis of the specialty is becoming increasingly well delineated. Anesthesiologists have established themselves in local, regional, and national forums as spokespersons not only for the specialty, but also for medicine in general. And the specialty at last may be emerging from the stereotype of a faceless, inarticulate, shy and retiring figure, whose outstanding characteristic was the cloying odor of diethel ether! Technology has moved into the specialty on seven league boots. Just as an example, the basic design of the anesthesia machine was stable between the early 1950s and certainly the late 1970s. Suddenly, in the blink of an eye, our anesthesia machines are becoming intelligent, are utilizing heads-up displays, and are becoming more and more capable of writing the anesthesia record. Monitoring standards for anesthesia have burgeoned to the point that almost every aspect of the specialty is impinged upon by some rule and some "thou will or thou will not. " The importation and creation of terminology is exploding. In fact, one of the problems in updating this book was deciding when to stop. The author hopes that the goal of creating a snapshot in time through definitions of commonly used words and phrases has been achieved.

Download or read book Sport and Physical Activity in the Heat written by Douglas J. Casa and published by Springer. This book was released on 2018-02-19 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book is the first of its kind to specifically explore the science, medicine, challenges and successful experiences of assisting those who must perform and thrive in hot conditions, with an eye toward maximizing both performance and safety. Beginning with both human and comparative physiology as it relates to coping with the heat, key concepts are subsequently elaborated, including heat acclimatization, work-to-rest ratios, hydration, sleep, the effects of altitude, and the use of drugs and supplements. The sections that follow discuss heat-related considerations in individual and team sports and other populations, monitoring techniques, and medical and legal issues. Athletes, warfighters and laborers are often forced to perform intense physical activity in the heat as a part of their jobs or lifestyle. The process of properly preparing for this challenge is multifaceted and often not fully understood or utilized. Sport and Physical Activity in the Heat is an excellent resource for team physicians, high-level coaches, serious athletes, athletic trainers, exercise scientists, strength and conditioning coaches, industrial hygienists, military commanders, or anyone involved in the process of maximizing performance and safety during exercise in the heat for the athlete, warfighter, or laborer.
Download or read book Basic Medical Sciences for MRCP written by Philippa J. Easterbrook and published by Churchill Livingstone. This book was released on 2005 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: A revision book intended primarily for candidates sitting their MRCP Part 1 examination and which covers all the essential basic sciences. It focuses on the recurring themes which come up in the questions. The book also includes a chapter on clinical pharmacology (which alone accounts for up to 30% of the questions), looking at aspects of drug-induced disease and drug interactions. Finally there is a chapter on statistics and epidemiology which is rarely covered in other texts, but is often included in the exam. Despite the changes to the teaching of the undergraduate in medicine and the integration of the basic sciences with clinical education, the junior doctor, faced with postgraduate examinations, is always going to be poorly prepared for those increasingly important subjects. This book presents the essential information in the form of lists, tables, diagrams and flow charts.
