Evidence-based practice (EBP) is becoming the standard for medicine and allied health, so it is not surprising that athletic training and exercise science are also adopting evidence-based practice. For you to become a professional in these fields, you must understand what constitutes evidence-based practice and to which types of questions it can be applied. These issues form the discussion of Chapters 1 and 2. In Chapter 3, you will learn about outcome measures dealing with disease and disability, along with performance measures more associated with fitness and sports performance. At the close of this section, in Chapter 4, you will learn about statistical methods for compiling outcome measures and how researchers interpret these statistical values. With this information you can then apply their findings to your clinical questions.
