Available in PDF, EPUB and Kindle. Book excerpt: Essay from the year 2016 in the subject Medicine - Public Health, grade: 1, Egerton University, language: English, abstract: Over the years, exercise science has evolved to introduce new dimensions into the way energy is utilized in the body. During sports activities such as athletics, cycling and swimming, endurance for long hours is necessary for the maintenance of high muscle activity. Ordinarily, body muscles are responsible for generating chemical energy which is utilized during physical activity. Therefore, energy reserves in the body tend to be depleted, especially after prolonged exposure to strenuous exercise such as running. This applies to sprinters as well as, long-distance runners. This phenomenon is also experienced by people who engage in strenuous physical exercise, rather than sports. On the other hand, strenuous exercises including sporting activities involve a high level of dehydration. This leads to a significant loss of body fluids, as well as salts. These factors have prompted sporting people to look for remedies for energy depletion and dehydration, in order to maintain endurance in physical activities such as athletics. In theory, these remedies are referred to as ergogenic aids. An ergogenic aid can be defined as a mechanical, physical, psychological, nutritional, or a pharmacological substance that either limits physiological capacity by removing subjective restraints or directly enhances physiological variables in the body, especially those related to exercise performance. According to the definition of ergogenic aids, it is apparent that steroids are considered some of the most principal ergogenic compounds which can be used in sports. This is so because steroids tend to increase muscle activity, especially during strenuous exercises. Ordinarily, steroids have been in clinical use as pharmacological substances for the treatment of an array of health conditions. They have also been used as nutritional supplements for enhancing hormone production, and alleviation of anxiety. This implies that steroids possess psychological functions in the body. As such, steroids are ergogenic aids, and this is why athletes are prohibited from taking steroids because they alter their actual performance by providing them with a competitive advantage. It is believed that steroids enhance exercise performance, more or less the same as other pharmacological ergogenic aids.

Download or read book The Role of Protein and Amino Acids in Sustaining and Enhancing Performance written by Institute of Medicine and published by National Academies Press. This book was released on 1999-09-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.

Download or read book Sport and Exercise Nutrition written by Susan A. Lanham-New and published by John Wiley & Sons. This book was released on 2011-08-10 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Please note that digital editions do not include all the illustrations found in the printed book. Now widely adopted on courses throughout the world, the prestigious Nutrition Society Textbook series provides students with the scientific basics in nutrition in the context of a systems and disease approach rather than on a nutrient by nutrient basis. In addition books provide a means to enable teachers and students to explore the core principles of nutrition and to apply these throughout their training to foster critical thinking at all times. This NS Textbook on Sport and Exercise Nutrition has been written to cover the latest information on the science and practice of sport and exercise nutrition. A key concept behind this textbook is that it aims to combine the viewpoints of world leading nutrition experts from both academia/research and a practical stand point. Plus where necessary there are additional practitioner based authors to ensure theory is translated into practice for each chapter in the form of either ‘practice tips' or ‘information sheets' at the end of relevant chapters. The textbook in essence can be divided into three distinct but integrated parts: Part 1: covers the key components of the science that supports the practice of sport and exercise nutrition including comprehensive reviews on: nutrients both in general and as exercise fuels; exercise physiology; hydration, micronutrients; and supplements. Part 2: moves into focusing on specific nutrition strategies to support different types of training including: resistance; power/sprint; middle distance/speed endurance; endurance; technical/skill, team; and specific competition nutrition needs. The unique format of this textbook is that it breaks down nutrition support into training specific as opposed to the traditional sport specific support. This reflects the majority of current sport and exercise requirements of the need to undertake concurrent training and therefore facilitating targeted nutrition support to the different training components through the various macro and micro training cycles. Part 3: explores some of the practical issues encountered in working in the sport and exercise nutrition field and includes key sport related topics such as: disability sport; weight management; eating disorders; bone and gut health; immunity; injury; travel; and special populations and situations. READERSHIP: Students of nutrition and dietetics at both undergraduate and postgraduate level. All those working in the field of nutrition and related health sciences.

Download or read book Caffeine in Food and Dietary Supplements written by Leslie A. Pray and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caffeine in Food and Dietary Supplements is the summary of a workshop convened by the Institute of Medicine in August 2013 to review the available science on safe levels of caffeine consumption in foods, beverages, and dietary supplements and to identify data gaps. Scientists with expertise in food safety, nutrition, pharmacology, psychology, toxicology, and related disciplines; medical professionals with pediatric and adult patient experience in cardiology, neurology, and psychiatry; public health professionals; food industry representatives; regulatory experts; and consumer advocates discussed the safety of caffeine in food and dietary supplements, including, but not limited to, caffeinated beverage products, and identified data gaps. Caffeine, a central nervous stimulant, is arguably the most frequently ingested pharmacologically active substance in the world. Occurring naturally in more than 60 plants, including coffee beans, tea leaves, cola nuts and cocoa pods, caffeine has been part of innumerable cultures for centuries. But the caffeine-in-food landscape is changing. There are an array of new caffeine-containing energy products, from waffles to sunflower seeds, jelly beans to syrup, even bottled water, entering the marketplace. Years of scientific research have shown that moderate consumption by healthy adults of products containing naturally-occurring caffeine is not associated with adverse health effects. The changing caffeine landscape raises concerns about safety and whether any of these new products might be targeting populations not normally associated with caffeine consumption, namely children and adolescents, and whether caffeine poses a greater health risk to those populations than it does for healthy adults. This report delineates vulnerable populations who may be at risk from caffeine exposure; describes caffeine exposure and risk of cardiovascular and other health effects on vulnerable populations, including additive effects with other ingredients and effects related to pre-existing conditions; explores safe caffeine exposure levels for general and vulnerable populations; and identifies data gaps on caffeine stimulant effects.
