In accordance with the Dublin Descriptors, at the end of the course and in order to pass the exam, the student must demonstrate that:
1. Have achieved a knowledge and an ability to understand physiology that allows him to set up the discussion of theoretical issues in a logical and complete way;
2. Knowing how to set up the treatment of applicative problems in the field of exercise physiology, using the knowledge of human physiology;
3. Knowing how to autonomously and motivatedly evaluate any different opinions on problematic aspects of human physiology;
4. Knowing how to express one's knowledge in scientific language and vocabulary;
5. Demonstrate having achieved a good learning ability, not only in the form of memorizing the information studied, but also in the form of organizing one's own thoughts around such information.

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

The teacher will be available for meetings with groups of students or individuals, in presence and/or by videoconference, to fill gaps in the initial preparation and to clarify doubts or curiosities that arose during the lessons. In the event of a negative outcome of the exam, the teacher will also be available to identify the points that can be improved in the approach to the study of the subject.

Teaching

Frontal lessons.

Attendance

The student must possess the knowledge of chemistry, physics, biology, biochemistry and human anatomy preparatory to the study of physiology. If the student finds deficiencies in his basic preparation that hinder the understanding of the topics covered, he will have to fill the deficiencies, reporting the problem to the teacher if he sees it useful. Attending students are required to acquire at least sufficient preparation on all the topics of the programme.

Course books

Recommended texts (one of the following):

R.M. Berne, M.N. Levy, B.M. Koeppen, B.A. Stanton, Physiology, Casa Editrice Ambrosiana, 2019.

B.C. Guyton, J.E. Hall, Medical physiology, EDRA, 2017.

W.F. Boron, E.L. Boulpaep, Medical physiology, EDRA, 2017.

Wilmore-Costill, Exercise and Sport Physiology, Calzetti Mariucci

It is considered useful to clarify that there are no lecture notes authorized by the teacher. The use of notes cannot in any way replace the study of good texts. The study of one or more texts cannot replace attendance at the lessons, nor, on the other hand, does attendance at the lessons exempt from the systematic study of one or more texts.

Assessment

Oral interview. The acquisition of the specific vocabulary of the discipline, the notions acquired on the topics of the program, the ability to establish relationships between the different functions and between the themes of physiology and the knowledge of chemistry, physics, biological chemistry and human anatomy will be evaluated previously acquired, the ability to articulate a reasoning, in order to address problems of general physiology and exercise physiology in particular.

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.

Teaching

All the iconographic material relating to the lessons held will be made available on the blended learning platform moodle. Furthermore, summaries of the lessons will be published on the same platform which, obviously, must be considered as explanatory of the topics covered in the program and not a substitute for studying in textbooks.

Attendance

Non-attending students are required to acquire at least sufficient preparation on all the topics of the programme, possibly using additional textbooks which may be indicated by the teacher on the basis of individual needs.
