Mark H. Anshel, PhD, is professor emeritus in the Department of Health and Human Performance at Middle Tennessee State University. Dr. Anshel received his BS in physical education from Illinois State University, his MA in the psychology of motor performance from McGill University, and his PhD in the psychology of movement performance from Florida State University. He has authored more than 145 journal articles, 15 book chapters, and 13 full books, including Aerobics for Fitness (5th ed.), Applied Exercise Psychology: A Practitioner's Guide to Improving Client Health and Fitness, Applied Health Fitness Psychology, In Praise of Failure: The Value of Overcoming Mistakes in Sports and in Life, Intervention Strategies for Changing Health Behavior, and Sport Psychology: From Theory to Practice (5th ed.). Dr. Anshel's career has addressed two related fields: sport psychology and exercise psychology. Within sport psychology, his primary area of research has been understanding the coping process in performance. In particular, he has studied the personal factors (e.g., coping style, resilience, mental toughness, skill level, age, gender, cultural background) and situational factors (e.g., chronic vs. acute nature, presence of observers or audience members, level of self-control) that influence whether events are considered stressful, as well as the most effective ways of managing such events. Within exercise psychology, his primary area of research has been the development, validation, and application of the disconnected values model, an intervention that encourages people to replace their unhealthy habits with healthier, more desirable ones. In his consulting practice, Dr. Anshel has applied performance psychology concepts to assist a variety of clients, including athletes and exercisers, coaches, law enforcement officers, sports rehabilitation professionals, members of the performing arts (e.g., dancers, actors, musicians), and corporate employees.
