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 individuals movement
• Qualitative analysis involves a systematic
  analysis of movement based on biomechanical
  concepts and/ or anatomical components but
  without
• actual measurement

SEGMENTAL ANALYSIS

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

11

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

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.

Why learn about Biomechanics?
20
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

The Interdisciplinary Nature of QA
Motor Development
Biomechanics

• 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.

Many terms are used synonymously - gt 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.

26

• 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

27

• 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

EVALUATION1. LABORATORY ASSIGNMENTS 35

• This section will involve 4 take home activities
  each worth 5

31
QUIZ

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

32
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.
