The benefits of a healthy lifestyle are well documented, yet many people continue to struggle with sedentary behavior and obesity. In Biologic Regulation of Physical Activity, Dr. Thomas W. Rowland posits a distinct possibility of the existence of a central biologic controller of activity. If harnessed, this mechanism could lead to breakthroughs in health science professionals’ quest for more effective ways of helping people be more active and, as a result, healthier. Rowland is one of the most well-respected pediatric cardiologists in the United States. He has authored three other books and more than 150 journal articles and has served in several key national leadership positions in pediatric medicine. In Biologic Regulation of Physical Activity, Rowland uses his expertise, along with numerous references and direct quotes from expert witnesses, to provide a detailed account of how current research may support the existence of a biologic regulator--a mechanism in the brain that involuntarily controls biological processes--associated with physical activity. Rowland proposes a possible mechanism for such a control and explores the implications of this theory. This developing area of research and theory offers a new lens through which health professionals and those who research issues related to obesity, physical activity adherence, and sedentary behaviors can view their work. The book moves methodically through the research, rationale, and implications of a biologic regulator of physical activity. In part I, Surveying the Evidence, readers are guided through a litany of research--both on humans and on animals--that provides support for the existence of a biologic regulator. (...).
