Book Description
Because athletes often seek to enhance their performance and body composition through nutrition, researchers must continue to investigate the current dietary consumption and the relationship of diet to body composition to best individualize nutrition guidance for athletes. Exploration of sex differences and sport specific differences in dietary intake provides insight on possible nutrition trends in specific athlete populations and risks for deficiencies. Calcium, magnesium, and zinc affect physiological mechanisms and systems needed for athletic performance, such as calcium for bone health; magnesium for energy production; and, zinc for the function of hundreds of enzymes and proteins. One purpose of our research was to determine the dietary intake of calcium, magnesium, and zinc in female and male athletes, including runners, triathletes, rowers, CrossFit athletes, and General athletes, 18 years of age and older. We also investigated the presence of sex differences and sport specific differences in dietary intake of these minerals. Finally, we examined possible correlations among these mineral intakes and body composition (bone mineral density [BMD] and percent body fat) to determine the strongest predictors of body composition. We evaluated the dietary intake and body composition of 247 athletes, 129 women and 118 men, with a mean age of 34.86±11.38 years. The population included runners (n=90), General athletes (n=59), triathletes (n=43), rowers (n=34), and CrossFit athletes (n=21). Dietary intake was assessed via a 2005 Block Food Frequency Questionnaire (FFQ), which analyzes one's annual macronutrient and micronutrient intake. Bone mineral density (total body, lumbar spine, and dual femoral neck) and percent body fat were measured using dual-energy x-ray absorptiometry (DXA). One sample T-tests were used to compare the dietary intake of calcium, magnesium, and zinc to the Recommended Dietary Allowances (RDA) in female and male athletes. A one-way analysis of variance (ANOVA) was used to determine differences in dietary intake between the sexes and among various sports. Multiple regression analyses were utilized to identify the strongest predictors for BMD and percent body fat. All data were analyzed using standard SPSS version 25 software, with the alpha a priori set at 0.05. We found that across all female athletes, dietary intake of calcium was significantly below the RDA of 1000 mg/day (801.3 mg/day ± 264.9, p

Book Description
Sport Nutrition for Health and Performance, Second Edition, will help students and practitioners understand the function of the nutrients in the body and how these nutrients affect health and athletic performance. The authors present clear, comprehensive, and accurate nutrition information that may be applied to a variety of careers. The text provides students with practical knowledge in exercise and nutrition science, and it keeps practitioners on the cutting edge of current research and practices in the field. Using the authors’ extensive backgrounds in nutrition, exercise physiology, and fitness, the text combines micronutrients into functional groupings to provide an easy framework for understanding how these nutrients can influence exercise performance and good health for both athletes and active individuals. This unique presentation allows readers to fully understand why proper nutrition helps athletes prevent injury, enhance recovery, improve daily workouts, and maintain optimal health and body weight. This second edition has been thoroughly revised and updated to reflect the latest issues, guidelines, and recommendations for active individuals. Chapters dealing with macronutrients and micronutrients have been entirely rewritten, and all chapters have been revised to reflect the latest Dietary Reference Intakes, USDA Food Guide Pyramid, Food Pyramid for Athletes, Dietary Guidelines for Americans, and physical activity recommendations from various organizations, including the 2008 Physical Activity Guidelines by DHHS. Following are some of the current topics discussed in the text: • Carbohydrate recommendations for athletes before, during, and after exercise • Protein requirements of athletes based on the latest research • Updated evaluation of the fat needs of athletes and the role of fat loading • An evidence-based reexamination of various diets and techniques used for weight loss • New research on body composition assessments and standards • The latest on controversial nutrition issues such as the role of protein, vitamin D, and energy in bone health and new criteria for assessing bone health in young adults • New nutrition and fitness assessments, questionnaires, and methods for measuring energy expenditure • Updated information on various topics such as the issues of the active female, ergogenic aids, energy balance, and fluid balance Sport Nutrition for Health and Performance, Second Edition, has also been improved with an attractive two-color format, new artwork, and a slimmer design that allows the text to maintain the content while reducing “backpack bulge.” The text also includes an online image bank that instructors may use to create customized PowerPoint presentations using artwork, tables, and figures from each chapter.

Book Description
This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

Book Description
Designed to address the nutritional needs of women over the age of 18 who partake in sports on a regular basis, Nutrition and the Female Athlete: From Research to Practice highlights nutritional concerns specific to active women. It discusses the link between nutrition and athletic performance and translates research into practical applications for health, fitness, and nutrition professionals. The book addresses gender differences in substrate utilization and the implications for how these differences might translate into different macronutrient requirements for female athletes. It covers vitamins and minerals that are often lacking in the diets of female athletes and presents special considerations for individuals with disordered eating, menstrual dysfunction, and low bone-mineral density.
