[A historical perspective on the evolution of the concepts of motor activity and physical exercise in medicine].

A historical analysis of Western medicine clearly indicates high attention to the body dimension and to corporeal functions. Even if what today may be defined "the science of physical exercise in medicine" goes back only to the last fifty years, the great Mediterranean cultures have always dedicated great care to the harmonic development of the human body. The importance of the role of physical exercise in maintaining an appropriate health status is mentioned in the Hippocratic Corpus (V-IV century before Christ). In the contemporaneous Hippocratic Oath one may read that the physicians of the Hippocratic School are called upon to "regulate the lifestyle of sick people in the light of their well being". At that time the prescriptions regarding patients' lifestyle, taking into account the limited effectiveness of therapeutic measures, were primarily concentrated on an appropriate diet and motor activity. This historical review describes the evolution of physical activity in medicine with regard to the current awareness of its relevance at every stage of life; the presentation of the historical roots of the concepts of motor activity and of physical exercise and of their progress through time aims at defining their current preventive, therapeutic and rehabilitative roles.
