This book was released on 2016 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well documented that consuming carbohydrates (CHO) prior to exercise has been shown to alter metabolism. There are many ways that CHO ingestion affects substrate utilization and blood glucose dynamics at the start of exercise. Changes in the concentrations of blood glucose, insulin, glucagon, free fatty acids (FFAs) as well as varying utilizations of different substrates have been observed. Each of these responses is reflective of the body’s capacity to maintain homeostasis through different physiological conditions and demands. PURPOSE: The aim is to deduce how varying amounts (approximately 0, 12.5, 25 and 50g for a 70 kg person) of pre-exercise sucrose ingestion effects metabolism including blood glucose concentration and fat oxidation during 30 minutes of moderate intense exercise. METHODS: This will be a randomized crossover study. After the initial assessment of baseline data (VO2peak), participants will be asked to perform four cycling trials at 50% of VO2peak for 30 minutes. Forty-five minutes before each exercise trial, participants will consume 0, 12.5, 25 and 50g (for a 70kg person) of sucrose. VO2 and VCO2 will be collected for 15 minutes prior to exercise and for the entire 30 minutes of cycling. Blood glucose will be obtained through the finger prick method and collected directly prior to exercise, 5, 15 and 30 minutes into cycling. Heart rate and rate of perceived exertion will be measured every 5 minutes of exercise. DISCUSSION: It is speculated that a small dose (12.5g for a 70kg person) of pre-exercise sucrose consumption will be able to demonstrate a decline in blood glucose concentration during exercise with a step-wise reduction in fat oxidation. This dose response curve will display the sensitivity of metabolism to ingested sucrose.
Download or read book The Effect of Diet and Nutrition on Postprandial Metabolism written by François Mariotti and published by MDPI. This book was released on 2020-11-04 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The postprandial period is the metabolic phase that directly follows the ingestion of a meal. This period is critical to the handling of nutrients to feed the body throughout the whole day but it is also a time of challenge for the body’s metabolism, which has to be flexible and adaptable regarding the quantity and the quality of the nutrient intake. Changes in postprandial metabolism have been considered to be potential early markers in the pathophysiological course, finally leading to an increased risk of disease development. This book aimed to broaden and add to the research on the importance of postprandial metabolism in nutrition. The book includes literature reviews that cover the broad state of the art of our knowledge about postprandial metabolism, fine original studies of the complex changes in metabolism, and the physiological processes that are considered to drive the onset of pathogenesis. Finally, a series of examples on how nutrient content (especially proteins, sucrose, and lipids) can influence the postprandial metabolism over a wide range of phenomena operating during the postprandial period and how they could contribute to tipping the body towards adverse health processes.

Download or read book Nutrient Timing written by Chad M. Kerksick and published by CRC Press. This book was released on 2011-10-20 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sports nutrition has evolved beyond what to eat and how much to eat to now include the question of when to eat. A hot topic in sports nutrition, nutrient timing is a dietary concept that takes into account time as a missing dimension in athletic performance and recovery. Not only is the consumption of nutrients in ideal amounts and proportions important, but the timing with which they are administered is also of prime importance—the right nutrients at the ideal time to affect performance and muscular growth. Nutrient Timing: Metabolic Optimization for Health, Performance, and Recovery presents the most authoritative text to date that scientifically examines the contemporary topic of nutrient timing. Worldwide research continues to rapidly explore the metabolic impact of nutrient timing and how its proper application may help to improve performance. With contributions from scientists and practitioners in the field, this book gathers the latest evidence-based information on this cutting-edge area. The chapters cover macronutrients—carbohydrates, proteins, and lipids—and their role in sporting activity, as well as an examination of vitamins and minerals. The core of the book focuses on pre-exercise, mid-exercise, and post-exercise considerations for both resistance and aerobically mediated activity. Using the models presented, individuals may improve performance, promote optimal adaptations to training, maximize recovery, and facilitate healthy interactions with their environment. The final chapters of the book describe future concepts in nutrient timing, including the impact of protein source in the context of timing, how nutrient timing can fit in with a comprehensive recovery program, and the application of the ideas discussed in unique populations such as the aged, the military, and populations interested in weight loss. This text provides solid data from the scientists themselves, giving researchers, teachers, coaches, and medical and health care professionals the necessary information they need to accurately and effectively determine how nutrients can impact certain outcomes and, most importantly, how to practically apply this knowledge.

This book was released on 2015-07-21 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrient timing is a popular nutritional strategy that involves the consumption of combinations of nutrients-primarily protein and carbohydrate-in and around an exercise session. Some have claimed that this approach can produce dramatic improvements in body composition. It has even been postulated that the timing of nutritional consumption may be more important than the absolute daily intake of nutrients. The post-exercise period is widely considered the most critical part of nutrient timing. Theoretically, consuming the proper ratio of nutrients during this time not only initiates the rebuilding of damaged muscle tissue and restoration of energy reserves, but it does so in a supercompensated fashion that enhances both body composition and exercise performance. Several researchers have made reference to an anabolic "window of opportunity" whereby a limited time exists after training to optimize training-related muscular adaptations. However, the importance - and even the existence - of a post-exercise 'window' can vary according to a number of factors. Not only is nutrient timing research open to question in terms of applicability, but recent evidence has directly challenged the classical view of the relevance of post-exercise nutritional intake with respect to anabolism. Therefore, the purpose of this paper will be twofold: 1) to review the existing literature on the effects of nutrient timing with respect to post-exercise muscular adaptations, and; 2) to draw relevant conclusions that allow practical, evidence-based nutritional recommendations to be made for maximizing the anabolic response to exercise.

This text adequately addresses how athletes can do so in an effective and practical fashion, optimizing performance and maintaining health.
Download or read book Human Substrate Metabolism at Upper Oxidative Capacities written by Raul de Souza Silveira and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Carbohydrate (CHO) and fat are the main substrates to fuel prolonged endurance exercise, each having its oxidation patterns regulated by several factors such as intensity, duration and mode of the activity, dietary intake pattern, muscle glycogen concentrations, gender and training status. Exercising at intensities where fat oxidation rates are high has been shown to induce metabolic benefits in recreational and health-oriented sportsmen. The exercise intensity (Fatpeak) eliciting peak fat oxidation rates is therefore of particular interest when aiming to prescribe exercise for the purpose of fat oxidation and related metabolic effects. Although running and walking are feasible and popular among the target population, no reliable protocols are available to assess Fatpeak as well as its actual velocity (VPFO) during treadmill ergometry. Moreover, to date, it remains unclear how pre-exercise CHO availability modulates the oxidative regulation of substrates when exercise is conducted at the intensity where the individual...

Download or read book Exercise and Diabetes written by Sheri R. Colberg and published by American Diabetes Association. This book was released on 2013-05-30 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical movement has a positive effect on physical fitness, morbidity, and mortality in individuals with diabetes. Although exercise has long been considered a cornerstone of diabetes management, many health care providers fail to prescribe it. In addition, many fitness professionals may be unaware of the complexities of including physical activity in the management of diabetes. Giving patients or clients a full exercise prescription that take other chronic conditions commonly accompanying diabetes into account may be too time-consuming for or beyond the expertise of many health care and fitness professionals. The purpose of this book is to cover the recommended types and quantities of physical activities that can and should be undertaken by all individuals with any type of diabetes, along with precautions related to medication use and diabetes-related health complications. Medications used to control diabetes should augment lifestyle improvements like increased daily physical activity rather than replace them. Up until now, professional books with exercise information and prescriptions were not timely or interactive enough to easily provide busy professionals with access to the latest recommendations for each unique patient. However, simply instructing patients to “exercise more” is frequently not motivating or informative enough to get them regularly or safely active. This book is changing all that with its up-to-date and easy-to-prescribe exercise and physical activity recommendations and relevant case studies. Read and learn to quickly prescribe effective and appropriate exercise to everyone.
