Download or read book Impact of Caffeine on Strength and Endurance written by Ella Knight and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caffeine is a well-established ergogenic aid believed to increase strength and muscular endurance. An increase in strength suggests a centralized impact, or an “outflow” effect, on the central nervous system (CNS). An increase in muscular endurance suggests an impact of caffeine on peripheral factors such as the myoneural junction or others that locally impact muscular contractions. The present study was conducted to determine the predominant impact of caffeine, either on central or peripheral factors that govern muscular contraction, or both. Data concluded that (1.) muscular strength increased from control in both the caffeine and placebo trials, and (2.) there was no improvement in muscular endurance in the caffeine and placebo trial when compared to control; however, during the isokinetic endurance test, there was a modest increase in peak torque in the caffeine trial when compared to control. This study was conducted with approval from the Hanover College Human Subjects Institutional Review Board.
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 Effect of Caffeine on Muscular Strength and Muscular Endurance written by Blake Robertson and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine the optimal time to take caffeine I order to maximize muscular strength and muscular endurance. There have been many studies done that have shown that caffeine has the ability to improve both muscular strength and endurance due to many different effects that it has in the central nervous system. However, there is still a very intriguing question: when is the optimal time to take caffeine in order to maximize performance? It is known that caffeine has its peak effects occur about 45 minutes after ingestion. By taking caffeine 45 minutes before exercise, the peak effects would occur at the beginning of the workout, and by taking it 15 minutes before the exercise, the peak effects would occur in the middle of the workout, when the body is becoming fatigue. This study is aimed to figure out which of these scenarios is the most effective.

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.

Download or read book Cochrane Handbook for Systematic Reviews of Interventions written by Julian P. T. Higgins and published by Wiley. This book was released on 2008-11-24 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthcare providers, consumers, researchers and policy makers are inundated with unmanageable amounts of information, including evidence from healthcare research. It has become impossible for all to have the time and resources to find, appraise and interpret this evidence and incorporate it into healthcare decisions. Cochrane Reviews respond to this challenge by identifying, appraising and synthesizing research-based evidence and presenting it in a standardized format, published in The Cochrane Library (www.thecochranelibrary.com). The Cochrane Handbook for Systematic Reviews of Interventions contains methodological guidance for the preparation and maintenance of Cochrane intervention reviews. Written in a clear and accessible format, it is the essential manual for all those preparing, maintaining and reading Cochrane reviews. Many of the principles and methods described here are appropriate for systematic reviews applied to other types of research and to systematic reviews of interventions undertaken by others. It is hoped therefore that this book will be invaluable to all those who want to understand the role of systematic reviews, critically appraise published reviews or perform reviews themselves.
Download or read book Impact of Caffeine and Psychological Motivation on Muscular Performance written by Casey Dunn and published by . This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caffeine is known as a stimulating substance that can increase one’s mental alertness and give individuals that extra boost they may need throughout their day-to-day life. Not only has this been shown in daily routines, but studies researching of the effects of caffeine on muscular endurance and strength have found that it can generate many benefits, such as improving muscular performance and increasing the time it takes to reach fatigue (12). With this conclusive finding, can the psychological motivational effects of caffeine be seen during a workout using a “hyped” effect? This study was designed to explore the possible effects a placebo has on muscular endurance and strength in comparison to a caffeine supplement.
