Research Methods in Physical Activity, Eighth Edition, systematically guides students through the research process, introducing research methods, tools, and analysis techniques specifically for kinesiology and exercise science disciplines, including the subdisciplines of physical therapy, rehabilitation, and occupational therapy. The eighth edition continues its legacy with the authors’ trademark humor and is now enhanced with a new full-color layout. This reputable text provides step-by-step information for every aspect of the research process. Part I presents an overview of the research process, from preparing the research plan to understanding ethical issues in research and writing. Part II introduces statistical and measurement issues in research. Part III presents various approaches to research and methodology—including qualitative, quantitative, and mixed methods—while scholarly contributors offer advice for addressing sociohistorical, experimental, epidemiological, and philosophical research questions. Part IV details how to develop and organize research papers and presentations, and it includes guidance for describing results for publication in a scientific journal. Statistical tables and guides are available in the appendix. Joining longtime authors Jerry Thomas, EdD, and Stephen Silverman, EdD, are Philip Martin, PhD, and Jennifer Etnier, PhD, who bring fresh perspectives from the subdisciplines of biomechanics and sport and exercise psychology. Other enhancements to the eighth edition include the following: References have been updated throughout the text to present current research. Part II has undergone a major revision that makes statistical techniques more accessible. A new section on the Physical Activity Guidelines for Americans and other public health initiatives demonstrates epidemiology research in action. The chapter on philosophical research contains new issues from our increasingly diverse world, challenging students to think deeply. The full-color layout fosters an engaging learning experience and offers an enhanced data presentation. Research Methods in Physical Activity, Eighth Edition, employs learning aids that make the technical aspects of the research process approachable and easy to understand. Photos, anecdotes, and humorous stories throughout the text highlight practical applications to keep students engaged. A running glossary and key points emphasize important content. Review questions and prompts invite students to assess and apply their knowledge. Research Methods in Physical Activity, Eighth Edition, instills in students the confidence to devise, collect, analyze, and present their research in a competent manner. It is an essential text for all emerging researchers in physical activity.
