COURSE DESCRIPTION: This course will focus on the mechanical basis of human movement with some consideration given to the anatomical constraints that influence normal, athletic, and pathological movement. Topics covered will include linear and angular kinematics and kinetics of movement, equilibrium, and fluid mechanics.
COURSE TEXT: Biomechanical Basis of Human Movement,Joseph Hamilll & Kathleen M. Knutzen
COURSE OBJECTIVES:
1. Students will be provided a brief review of applied anatomy with particular reference to exercise and activity.2. Students will learn the value of solving human movement challenges from an athletic as well as from an injury and/or pathological perspective.
3. Units of measurement, differences in scalar and vector quantities and two-dimensional and three-dimensional methods of measurement will be discussed and addressed.
4. Linear kinematic quantities will be addressed as they apply to movement of the body as well as projectiles.
5. Angular kinematics will be examined and understood, especially as it applies to creation of general planar motion.
6. Newton's Laws of Motion with respect to linear and angular kinetics will be addressed as they have application to a understanding of inverse dynamics.
7. Center of gravity, equilibrium and fluid mechanics will be discussed and examined.
8. Students will have a greater understanding of various types of human motion and how these movements can be quantified.
9. Students will become more aware of technology and why it is important in the field of biomechanics, through labs, electronic class communication, and use of listservers to name a few.
REQUIREMENTS:
Written Exams- 2 @20% each 40%
Laboratories 20%
Research Project 20%
Final Exam 20%
TOTAL 100%
DESCRIPTION OF PROJECTS:
1. In-class activities will include lecture/presentation, small group discussion, written examinations, and in-class research projects.EXAMS:2. Out-of-class activities will include readings, study and project preparation.
3. Class Project Description (20%). Each student will be responsible for presenting an in- class group project concerning how one of the mechanical constructs we examine during the semester influences normal, athletic, or pathological movement. The presentation should be planned for 45 minutes with 5 minutes at the end for questions and/or comment.
4. There will be four laboratories throughout the semester that will involve reading and intepreting data from graphs.
1. Projectile Path of COM2. Interpretation of Combined Kinematic and EMG Data
3. Interpretation of Kinematic and Force Data
4. Interpretation of GRF and Impulse
Exam #1 (20%) will cover linear and angular kinematic quantities and how they relate to movement.
Exam #2 (20%) will cover linear and angular kinetic quantities, and equilibrium and how they relate to movement.
Final Exam (20%) will be comprehensive and will cover all information
presented throughout the course including guest lecture information and
student projects.
EVALUATION SCALE:

ATTENDANCE POLICY:
1. Students will be allowed two (2) unexcused absences, except during major evaluations. EACH UNEXCUSED ABSENCES in excess of two (2) will result in 2% being deducted from your final average.2. Class will begin and end in a timely manner. You are expected to be prepared when class begins. Persistent tardiness will not be tolerated and may result in loss of points.
3. You are responsible for any work missed when you fail to attend class.
MAKE-UP POLICY:
1. Make-up exams will be given at the discretion of the professor when extenuating circumstances exist. It is the studentís responsibility to see the professor within three calendar days to request a make-up exam time and date.2. Assignments that are not turned in at the designated time will be accepted at the discretion of the professor. Be aware that unusual circumstances must exist for acceptance of late assignments, and if accepted, points will be deducted based on tardiness of assignment.
ACADEMIC HONOR CODE:
Students will be expected to abide by the academic honor code found
in the most current edition of the Student Handbook.
