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.
Prerequisites
It is highly recommended that students have obtained positive rating in the disciplines of "Mathematical Analysis I and II", "Physics IB", "Introduction to Biomaterials" and "Anatomy".
Subject matter
2 . Mechanical properties of tissues
Mechanical loads on the human body
Relationship Stress / Strain
Hard tissues - bones
Viscoelasticity .
Modeling of the visco-elastic properties
3 . Kinematics and Kinetics
Global and local referential;
Center of gravity
Kinematic calculus from the experimental data
4. Biomechanics of Motion and Joints
Classification of joints & types of motion
Kinematics of joints
Simulation & Modeling
5. Biomechanics of muscle contraction
Skeletal muscle;
Sliding filament theory
Motor unit and muscle contraction;
Hill equation
Modulation of skeletal muscle
Electromyography
6. Heart Biomechanics
Cardiac muscle;
Electrocardiogram and heart activity
Modelling of the heart and cardiac wall stress
Laboratory sessions: the laboratorial activity consists in performing works by each student in group of 2 of the following practical works:
1. Electromiography I
2. Electromiography II
3. Electrocardiography-ECG

Teaching method
Teaching consists of following components:
- Lectures (TEOR), where the fundamental concepts of the chair are transmitted, exemplified and discussed.
- The practical component (PRAT) that consists on performing of 3 laboratory sessions. This component provides learning of measurements of physiological signals of the human body by Biopac equipment, as well as analyzes and interprets the results. The laboratory work is carried out in groups of two students with delivery of the report at the end of the respective class. In addition, in practical classes, problems are solved.
