Biomechanics
Objectives
In this discipline will be introduced the concepts and formalisms of Biomechanics framed with examples of applications and the laboratory classes.
It is intended that at the end of the course, students demonstrates the bases for the understanding and application of key models used in Biomechanics and resulting equations, particularly in the study of movement and joints, mechanical properties of bones, contraction of skeletal, smooth and cardiac muscles.

Teaching method
Teaching consists of three components:
- Lectures (TEOR), where the fundamental concepts of the chair are transmitted, exemplified and discussed.
- Practical component (PRAT) that consists of performing of 3 laboratory sessions. This component provides learning of measurements of physiological signals of the human body by Biopac equipment, as well as analyse and interprets the results.
- Seminar (SEM) which consists of the preparation of work on a topic proposed by Professor.
The PRAT and SEM are performed by groups of two students
