HSS 387 – Biomechanics – Motion analysis of a movement: comparison of two conditions
Motion analysis of a movement: comparison of two conditions
Purpose: The ability to observe a movement task critically and describe the movement accurately and precisely is an essential element to performing a job as a(n) fitness/exercise specialist, athletic coach, PE teacher, and clinician. Accurate and clear descriptions of a movement task allow you to communicate with other professionals efficiently, and the identification of the muscles involved in the movement task allow you to plan and prescribe effective exercises for your clients/patients. Additionally, the ability to recognize different movement patterns detected between two individuals permits you to further improve the effectiveness of your exercise prescription.
The purpose of this assignment is to observe a movement task/exercise that is performed by two different types of individuals, either healthy/injured or skilled/less skilled. You will observe a set of time-series photos of the activity and break down each phase of the activity to identify various components of the movement task (joint movements/positions, joint range of motion, resistance forces, etc.). Based on the joint movement and the resistance force identified for each section of movement task, the students will draw inferences as to which muscles are active at that time and how these muscles are activated (identification of the role of muscles). Next, you will compose a written comparison of the movement tasks performed by the two individuals. You will identify the differences between the two individuals, problems associated with the movement by the injured/less skilled, and seek solutions (such as exercise prescription) to facilitate a more effective/normal movement. Finally, you will describe the implications of the effects of the prescribed exercises.
Submission: The assignment should be submitted via FolioTek (link in Blackboard) in PDF format with the student’s last name in the document title. If assignment is not submitted to FolioTek, no grade is given to the assignment. During submission of the paper portion of the assignment, the paper should be assessed for plagiarism using the Safe Assign function in Blackboard. The submission due date is indicated on the course calendar in the syllabus.
For each underlined phase of the movement task:
NOTE!!: You may NOT see much differences in the movement analysis tables, but you may want to make a note of small differences in variables such as joint angles, body orientations, jump height, etc. to discuss them in the paper process.
