Book Synopsis High-Intensity Exercise in Hypoxia - Beneficial Aspects and Potential Drawbacks by : Olivier Girard
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.
Book Synopsis Sports Nutrition & Performance Enhancing Supplements by : Abbie E. Smith-Ryan, Ph.D.
Download or read book Sports Nutrition & Performance Enhancing Supplements written by Abbie E. Smith-Ryan, Ph.D. and published by Linus Learning. This book was released on 2009 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Which of the following will yield the fastest measurable change in performance and/or body composition? (A) changes in training. (B) changes in diet. (C) use of sports supplements. (D) they all work equally well. If you answered 'C,' go to the head of the class. That's right; the proper use of sports supplements can produce changes in minutes (e.g. caffeine), days (e.g. creatine) and weeks (e.g. beta-alanine). Yet we are bombarded by muddled thinking from the mainstream media telling us that 'creatine causes cramps,' 'high protein diets are bad for your kidneys,' 'supplements aren't needed as long as you eat a balanced diet' and other ideas that are void of data. Sports Nutrition & Performance Enhancing Supplements (eds. Abbie Smith-Ryan PhD CSCS*D CISSN and Jose Antonio PhD FNSCA FISSN. Linus Publications) is a focused resource that will give you the latest sports nutrition science, and eradicate the intellectually lazy positions held so dearly by the anti-supplement crowd."--Amazon.
Download or read book OZONE written by Velio Bocci and published by Springer Science & Business Media. This book was released on 2010-10-05 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxygen-Ozone therapy is a complementary approach less known than homeopathy and acupuncture because it has come of age only three decades ago. This book clarifies that, in the often nebulous field of natural medicine, the biological bases of ozone therapy are totally in line with classical biochemistry, physiological and pharmacological knowledge. Ozone is an oxidizing molecule, a sort of super active oxygen, which, by reacting with blood components generates a number of chemical messengers responsible for activating crucial biological functions such as oxygen delivery, immune activation, release of hormones and induction of antioxidant enzymes, which is an exceptional property for correcting the chronic oxidative stress present in atherosclerosis, diabetes and cancer. Moreover, by inducing nitric oxide synthase, ozone therapy may mobilize endogenous stem cells, which will promote regeneration of ischemic tissues. The description of these phenomena offers the first comprehensive picture for understanding how ozone works and why. When properly used as a real drug within therapeutic range, ozone therapy does not only does not procure adverse effects but yields a feeling of wellness. Half the book describes the value of ozone treatment in several diseases, particularly cutanious infection and vascular diseases where ozone really behaves as a “wonder drug”. The book has been written for clinical researchers, physicians and ozone therapists, but also for the layman or the patient interested in this therapy.

This book was released on 2016-03-24 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book demonstrates how the latest insights into the physiopathology of the stress response can be integrated into clinical practice. The topic is particularly relevant since the metabolic changes triggered by acute stress, including adaptive responses such as resistance to anabolic signals, have recently been more precisely delineated. The underlying mechanisms of these changes are also now better understood. The authors analyse how these advances could result in better management and more effective prevention of the long-term clinical consequences of the alterations occurring during the acute phase. An international panel of respected experts discusses these topics and describes the management of some common clinical conditions.
