Book Description
Background: Mixed Martial Arts (MMA) is a growing sport that places competitors into specific weight classes to level the competition field. Athletes "cut weight" to compete in a weight class lower than their "walk around" weight. Techniques for cutting weight include dehydration, starvation and exercise in hot environments jeopardizing health and performance. Higher-protein diets (HPD) have been shown to improve weight loss by increasing satiety, thermogenesis, decreasing total energy intake, and maintain lean mass during periods of energy deficiency, such as weight loss. Research regarding the impact of HPD on performance is limited and conflicting. Specific Aims: The central hypothesis for this study was: HPD diets will elicit greater weight loss and enhance body composition compare to tradition low-fat diets in non-obese, active individuals. The three specific aims of this study are: 1) examine the effects of HPD on weight loss, 2) evaluate the impact of HPD of athletic performance, and 3) determine the effectiveness of HPD for accelerated weight loss. Methods: Military personnel participating in the Combatives program were recruited. Participants were assigned a HPD (40% CHO, 30% PRO, 30% fat), traditional low-fat, high-carbohydrate diet (65% CHO, 15% PRO, 20% fat), or an ad libitum diet for 12-day to 6-weeks depending on their training program. Fields tests for pre- and post-intervention measures of performance included: vertical jump and leg power index to measure explosive power, 600 meter shuttle run for anaerobic capacity and 1.5 mile run for aerobic capacity. Pre- and post-intervention of weight and body composition were determined using dual energy x-ray absorptiometry. Diet analysis software was used to determine nutrient intakes during the study. SPSS statistical software was used to determine descriptive statistics, paired t-tests, Pearson's Correlations and one-way ANOVA. Results & Conclusions: Due to the unanticipated high rate of dropout, statistical significance was difficult to determine, however, there was a trend for the HPD to elicit fat-free mass retention and it not negatively impact performance. Discrepancies in energy and nutrient intake made dietary comparison difficult. Future studies with larger samples and greater dietary control are needed to further evaluate the research goals of this study.

Book Description
Dietary supplement companies and the food industry spend millions to reach resistance trainers—often with exaggerated marketing messages—while health practitioners continue to counsel athletes that their interest in protein is misguided and even dangerous. There appears to be a disconnect between scientists and almost everyone else in sports nutrition. With so much conflicting information, it’s difficult to know who to believe. With contributions from the world’s foremost experts, Dietary Protein and Resistance Exercise delivers the uncut scientific truth about the role of dietary protein in the well-being of athletes. Updating and clarifying the issues surrounding purposeful protein intake and resistance trainers, this volume: Reviews the science-related history of protein and its consumption among strength athletes Analyzes the mechanisms behind what proteins do in muscle cells Describes protein’s effect on performance, recovery, and body composition Explores various populations that actively employ resistance training and dietary protein Discusses timing, type, and safety data regarding liberal protein diets and related supplements Includes sidebars, practical examples, and case studies—translating the science into a practical understanding of various protein-related topics Separating fact from fiction and providing the hard science behind the numbers, this volume demonstrates how changes in dietary protein intake may lead to measurable improvements in body composition, energy levels, and athletic performance.

Book Description
Knowing the basic nutrition requirements and combining them with proper training are the two most important factors for athletes to achieve peak performance levels. Nutritional Guidelines for Athletic Performance: The Training Table addresses these needs on a comprehensive basis from a training table perspective. Offering practical guidelines for practitioners and athletes, the book focuses on the key macronutrients that fuel daily metabolism and exercise training and explores differing needs for various athletes and their individual goals. Topics discussed include: General principles and physiology of caloric intake for all major macronutrients and how this pertains to both active and sedentary individuals Energy demands and nutritional requirements for strength-power athletes and elite competitors in endurance sports Protein, carbohydrate, fat, vitamin, and mineral needs of athletes The importance of optimal fluid and hydration during exercise How to determine body weight for a desired body fat percentage, recommended calorie consumption, dietary suggestions, and useful meal planning tools for a wide variety of caloric needs The difference between energy intake and energy expenditure and how athletes can eat to build muscle, lose fat, and optimize performance Scientific strategies on how to time exercise and food intake to more effectively replenish glycogen, increase protein synthesis, and blunt protein degradation How the physiological changes that accompany aging change nutrient needs and guidelines for older athletes on maximizing performance and maintaining health Structuring a diet containing appropriate amounts of macronutrients (protein, carbohydrates, and fat) and micronutrients (vitamins and minerals) can be a daunting task. This text adequately addresses how athletes can do so in an effective and practical fashion, optimizing performance and maintaining health.

Book Description
Athletes and their support personnel are constantly seeking evidence-informed recommendations to enhance athletic performance during competition and to optimize training-induced adaptations. Accordingly, nutritional and supplementation strategies are commonplace when seeking to achieve these aims, with such practices being implemented before, during, or after competition and/or training in a periodized manner. Performance nutrition is becoming increasingly specialized and needs to consider the diversity of athletes and the nature of the competitions. This Special Issue, Nutrition Support for Athletic Performance, describes recent advances in these areas.

Book Description
This book surveys the entire field of body composition as it relates to performance. It includes a clear definition of terminology and a discussion of the various methods for measuring body composition. The authored papers represent a state-of-the-art review of this controversial field and address questions such as: What is a better measure of body compositionâ€"body fat or lean body mass? Does being overweight for one's height really affect performance? The book also addresses the issue of physical appearance as it relates to body fatness and performance. It includes an in-depth discussion of many of the topics of interest to those involved in sports medicine and exercise physiology.
