Course Description
This course applies elementary principles of physics and math to analyze human movement. This analysis also focuses on the development of forces within muscles and their effect on initiating and controlling human movement.
Course Content
- Qualification of human movement description 鈥 Kinematics
The interrelationship between displacement, velocity and acceleration, both linear and angular, will be used to quantify human movement. Multi-segment motions will be the focus, including running and jumping. Attention to methods of data acquisition and reduction will be important.
It is expected that students will demonstrate an ability to use vector analysis to solve problems in determining velocities, displacement, and time of travel of object. Specifically, it is expected that students will:- Produce and interpret graphs, and determine relationships between kinematic variables in 2D
- Identify situations involving the use of kinematics and classical mechanics to quantify the kinematics
- Solve problems involving: displacement, initial velocity, average velocity, acceleration, time
- Forces that change motion 鈥 Kinetics
Using Newton鈥檚 Laws, the effect of internal and external forces on human motion will be explored. Impulse and momentum, in linear and angular terms, will be used to explore complex human movements. Examination of data acquisition and reduction will be made and used to acquire data for analysis.
It is expected that students will analyze forces acting on an object and predict their effects. Specifically, it is expected that students will:- Solve problems involving: force, mass, acceleration, friction, coefficient of friction, normal and shear forces, impulse, momentum, angular impulse, angular momentum, moment of inertia
- Construct free-body diagrams for objects in various situations and use them to solve problems involving balanced or unbalanced forces, objects on inclined surfaces
- Define work and power, identify where these variables are useful in assessing human motion and solve problems involving: force, displacement, work, power, and efficiency
- Differentiate between kinetic energy and gravitational potential energy and give examples of each and solve problems involving: rotational and translational kinetic energy, potential energy and spring energy
- State the law of conservation of momentum and determine whether a collision is elastic or inelastic
- Analyze conservation of momentum in two dimensions
- Muscles 鈥 generators of force
This section will deal with identifying the mechanical properties of skeletal muscle, how these properties influence muscle function, and will include the understanding of electromyographical (EMG) technique for recording muscle activation.
It is expected that students will analyze EMG measurable output during selected activities. Specifically, it is expected that students will:- Demonstrate an understanding of the elements of the human musculo-skeletal system and how their properties interact during human movement
- Be able to use the concepts of force-length, force-velocity, hysteresis, compression, tension, shear, strain, Young鈥檚 Modulus, to explain musculo-skeletal adaptation
- Apply knowledge of applied anatomy to describe human movement and motor skills in both anatomical and mechanical terms
- Become familiar with the interaction of the mechanical properties of the musculo-skeletal system as they affect human movement
- Be able to use surface electrodes over appropriate anatomical landmarks and record muscle activity during a range of human movements
- Use computer programs such as Microsoft Excel to analyze biomechanical data such as joint angle, force, torque, and electromyography
- Become familiar with the conceptual framework for EMG analysis of human movement and understand the physiological and biomechanical basis for recording electrical potentials from striated muscles using surface electrodes
