The aim of the course will be learning of basic concepts of general physiology and of knowledge and of conceptual instruments for representation of human body functions, of their hormonal and nervous control and of main adaptations to exercise, to training and to some special environments. The student will have to be able to substain a discussion about general homeostatic problems, and to analyze the contribution of the functions and of their integration.
