qualitative movement analysis principles

• QMA

  definition = systematic observation of quality of human movement for providing intervention to improve performance

  4 stages:

  • preparation
  • observation
  • evaluation
  • error correction
• Preparation

  • Gather relevant knowledge + prepare for observation
  • Collect knowledge about performer
  • Identify:
  • Purpose for analysis
  • Key features of the skill
  • Data collection methods
  • How and when the observation will take place
  • Consider: validity + reliability
  • ⭐Validity = tests capacity to measure what it is intended to measure
  • ⭐Reliability = ability to reproduce similar results in similar/identical conditions
  • Same: procedures + equipment + environment + tester
• Observation

  • Observing the performer
  • Take notes about performance
  • Video recording (preferred)
  • Reliable
  • Replay multiple times
  • Can slow down video
  • Athlete can conduct self analysis
  • More than one person can review it
  • Direct observation
  • Not as reliable
  • More subjective
  • Quick + more accessible
  • Dependant on memory of observer
  • Doesn’t allow for comparison
  • Can’t be viewed by athlete
• Evaluation

  • Analyst review footage and notes to judge quality
  • Evaluate performance
  • Identify errors:
  • What is the problem?
  • What is causing the problem?
  • How can the problem be corrected?
  • Reasons for movement error:
  • Psychosocial problems
  • Critical ability, strength, endurance, flexibility etc.
  • Skill performance deficiencies (technique, perceptual + decision error)
• Error correction

  • Based on interpretation of data observed
  • Feedback is provided to performer
  • Strategies are developed to fix or improve identified problems
