It has been well established that appropriate physical activity and exercise play an important role in promotion of health and fitness, prevention of disease and treatment and rehabilitation of health conditions. However, practice based on scientific evidence, in respect of the role and effectiveness of exercise interventions in prevention and treatment of diseases, has only been promoted and implemented in the fields of clinical exercise physiology, public health and medicine in recent years.
