Exercise, And Health |

The three previous editions of Nutrition, Weight Control, and Exercise covered a 15-year period between 1977 and 1992. Our primary objective in these editions was to bridge the gap between many introductory topics usually covered in nutrition courses and those courses that emphasized topics related to exercise and physical fitness. Our target audience was undergraduate majors enrolled in physical education and exercise science elective courses such as sports nutrition, human performance, and nutrition, as well as in diverse courses integrating introductory material on physical activity, diet, and weight control. While this approach seemed appropriate to these relatively focused areas, we always believed that basic information about nutrition and exercise should be part of many different curricula, not just a few. The explosion of new information in the last five years about such topics as the interrelated and protective role of both nutrition and physical activity in many disease processes, including coronary heart disease, cancer, osteoporosis, and obesity, has refocused our attention on course content. To this end, we have broadened our original textbook, starting with a new title, Introduction to Nutrition, Exercise, and Health. The term "health" in the title is added because our coverage in the area is more robust, and the relationship between exercise and nutrition and health is more direct. Examples include sections on exercise, nutrition, and osteoporosis, basic nutrition and cancer, physical activity and coronary heart disease prevention, primary and secondary risk factors and their relation to both diet and exercise, physical activity and pregnancy outcome, and the clear interrelationships among nutrition, weight control, and exercise. For the fourth edition, the pages are designed in a two column format; this was done to present current and relevant text and graphics close to the chapter's main text. There are also two new introductory chapters to make it easier for nonscience majors to integrate the basics of biology and chemistry, as well as the physiology of digestion and absorption, with the nutrition, exercise, and health content of the remaining 18 chapters. We believe these two chapters are essential to the expanded scope of the fourth edition. While they can serve as the starting point for most courses, this is not a requirement. The text content is of sufficient breadth to allow the instructor to select specific chapter groupings to meet a course's goals and requirements. There are also new chapters on food advertising, food packaging, and food labeling, and separate chapters devoted to carbohydrates, lipids, proteins, vitamins, minerals, and water. The 12 remaining chapters have been revised significantly to include the most recent scientific literature. Changes in the fourth edition include: Color graphics. There are a total of 245 new illustrations. There are five new appendices with updated information. • Appendix A is an expanded version of our previous caloric expenditure tables for various physical activities. It now includes the most popular recreational and household activities for both men and women. Up-to-date references for each chapter. In the textbook, key words and concepts are designated with bold type. These same key words and concepts are included in the Student Study Guide and Workbook in the order in which they appear in the textbook. As in the three previous editions, no attempt is made to be all inclusive or to cover the numerous related topics often attempted in some introductory texts. We believe the content is appropriate for introductory level courses in nutrition, especially those that emphasize exercise and health, obesity, weight control, and the evaluation of body composition. These areas are not covered in sufficient depth in introductory nutrition textbooks. The content is also appropriate for some classroom courses dealing with physical fitness and wellness at the university level, and for the formal professional preparation of individuals who specialize in exercise science, nutrition, health education, and some medically related disciplines in the health science fields such as nursing, physical therapy, and chiropractic. The book is divided into three main parts with chapter subdivisions. Part I is organized into 13 chapters. The introductory chapter reviews biology and chemistry basics related to nutrition and exercise. The focus is on definitions of common terms and major concepts that are important in studying the interactions among nutrition, exercise, and health. The subsequent chapters take a closer look at the five nutrients and attempt to answer the following questions: What are they? Where do they come from? What are their functions? In what foods are they found? How are they digested and absorbed? Chapter 9 discusses per capita food consumption patterns, food advertising, food packaging, and food labeling. The concept of optimal nutrition is explored in Chapter 10, and practical recommendations and guidelines are provided for the active man and woman. Chapter 11 emphasizes the importance of the food nutrients in sustaining physiologic function during moderate and more strenuous physical activity, while Chapter 12 focuses on the role of the ventilatory and circulatory systems in exercise. In Chapter 13, we discuss the energy value of foods, and how energy is extracted from food to power various forms of physical activity. Part II deals with topics relevant to body composition, obesity, and weight control. Chapter 14 discusses the underlying rationale for the evaluation of body composition and estimation of body fat and lean body weight. In Chapter 15, we define the term "overweight" in terms of the acceptable limits of body fat for a particular age range for men and women. We discuss the interrelated factors often associated with obesity, as well as the efficacy of diet and exercise as a treatment for the overfat condition. Chapter 16 deals with weight control. We discuss the questions of weight loss and weight gain within the framework of the "energy balance equation." In addition, a strategy is presented for quantifying food intake, and incorporating exercise and caloric restriction to achieve a desired rate of weight loss. Chapter 17 is concerned with the application of the principles of behavior modification, with emphasis on weight reduction by means of dietary modification and increased energy expenditure through moderate physical activity. Part III considers training for muscular strength and conditioning for anaerobic and aerobic power, as well as aging, exercise, and cardiovascular health.

This is a resource companion to the textbook. Its purpose is to facilitate student understanding of text content by focusing on key terms and concepts, and on specific questions within each chapter. Also included are sample test questions (fill-in, True-False, and Multiple Choice), and as far as we know, the first crossword puzzles dealing with nutrition, exercise, and health. Section II includes six self assessment tests. These tests are designed to provide a realistic appraisal of your status on important measures of nutrition, health, and fitness. The answers to the questions and crossword puzzles are included in one of the appendices. In two years of testing with the Student Study Guide and Workbook, there was an overall 87% student approval rating. Students improved their course grade significantly by using the workbook, often by a full letter grade or more! Integrating textbook material with assignments in the Student Study Guide and Workbook augments the learning process. |
