  3. COURSE INSTRUCTORS • February 21 – April 6 • Dr. Moira McPherson 343-8640 • SB-1019 • For work completed during the first 6 weeks, or for assistance with the functional anatomical analysis for the term project : • Dr. Tim Taha 343-8649 • SB-1003

  4. COURSE TIMES Lecture BB 1021 Monday 1:00 -2:30 Labs SB-1016 Dates TBA Wednesday12:30 - 2:30 Friday 12:30 - 2:30

  5. OBJECTIVE OF THE COURSE • The objective of this course is to present and apply a framework for qualitative analysis with the goal of improving technique(ie; movement effectiveness and/or efficiency) • - can be applied to a wide range of skills to individuals across the life span and across different skill levels

  6. QUANTITATIVE VS QUALITATIVE • Both kinematics and kinetics can be analyzed using a quantitative or qualitative approach • A quantitative analysis requires a numerical evaluation of an individual’s movement • Qualitative analysis involves a systematic analysis of movement based on biomechanical concepts and/ or anatomical components but without • actual measurement

  7. JOINTREACTIONFORCES

  8. SEGMENTAL ANALYSIS • We often make the assumption that the human skeleton can be represented as a series of links.

  9. Researchers have used everything from cones to spheres to form the links which best approximate the complexity of the human body.

  13. QUALITATIVE ANALYSIS • The ability to form accurate feedback based on qualitative analyses implies the systematic and critical observation of a motor skill performance and the subsequent identification of discrepancies between the observed and desired response. • It is an ability which requires both the abstract analysis of a task as well as the visual dissection of an observed performance.

  14. Why learn about Biomechanics?

  15. Qualitative Analysis in Kinesiology • Kinesiology professionals in a wide variety of careers use QA to improve human movement • Examples: Dance, teaching, coaching, athletic training, sports medicine, physical therapy, chiropractic, fitness and ergonomics

  16. The Interdisciplinary Nature of QA Motor Development • Skill analysis is a complex process made up of a number of equally important components, however it is the synthesis of these components that results in analytical competency. Biomechanics QA Anatomy/ Functional Anatomy Motor learning

  17. Many terms are used synonymously - > Definitions • Observation – (Lewis, 1980), concerned with sensation, perception, and attention to visual stimulus • Movement Analysis – refers to conceptualizing and identifying the demands of the skill/ movement.

  18. Skill Analysis – the process which includes the conceptual analysis of the movement, observing the movement, diagnosing discrepancies between the desired response and the observed response, and forming and providing remediation • - it is the precursor to the provision of feedback

  19. Technique – is respected when different motor components combine in a logical sequence, when there is summation of forces directed in the direction of the movement. • Optimal technique refers to the most mechanically efficient performance of a movement pattern within the constraints and requirements of the skill or activity

  20. A deterministic model RESULT FACTORS WHICH THE RESULT PRODUCE CRITICAL FEATURE CRITICAL FEATURE CRITICAL FEATURE CRITICAL FEATURE CRITICAL FEATURE CRITICAL FEATURE

  21. EVALUATION:1. LABORATORY ASSIGNMENTS 35% • This section will involve 4 take home activities each worth 5%

  22. QUIZ • There will be an in class quiz on the material presented during this section. • Date TBA

  23. 3. MAJOR QA PROJECT 30% • This project will involve the analysis of a specific skill from both a mechanical and functional anatomical perspective. Students will be required to videotape a performance of the skill using a variety of observation strategies . A deterministic and anatomical breakdown of the skill will be completed. Students will then complete the diagnosis and make suggestions for any remediation or refinements of the critical features which are necessary.

  24. WEEK 1 • NO IN LAB SESSION(Wed/Fri) THIS WEEK

  25. HOMEWORKREADINGS • Review biomechanics terms • Qualitative Analysis of Human Movement, Knudson & Morrison (1997) p3-14 • Chapter 2 – p15-24: Focus on Hay and Reid’s –Deterministic model, Norman’s model, intro to McPherson - A paradigm for skill analysis (p.24)

  26. HAVE A GOOD WEEK
