Qualitative Biomechanical Analysis to Improve Performance

Objectives:

  • Understand the difference between a qualitative and quantitative biomechanical analysis
  • List the steps involved in a qualitative biomechanical analysis for technique improvement
  • Understand the process of developing a theoretical mechanically based cause-and-effect model of a skill
  • Describe the important guidelines for observing a performance
  • Understand how to identify and evaluate errors in performance
  • Understand how to give instruction to students or athletes that will help them correct errors in technique

Show videos of amazing techniques

  1. Description
  2. Observation
  3. Evaluation
  4. Instruction
Description
  • Gain a fundamental knowledge of the skill
  • Know the rules (Why is this important? Example 1, Example 2)
    • Hockey
    • Discus
    • Pole Vault
    • Baseball
  • Purpose of the Skill (in mechanical terms)
  • Characteristics of Most Effective Technique
    • High Jump
Choose a skill: Write the purpose in mechanical terms and the characteristics of most effective technique

Observation
  • Who will you observe?
  • What will be the conditions?
  • Where will you observe from?
  • What will you look for?
Evaluation
  • Identify errors
  • Evaluate errors
    • Does the error expose the performer to the danger of injury?
    • Who are your clients?
    • How easy is it to correct the error?
    • Is the error a result of another error that occured earlier in the performance?
    • How great an effect does the error have on the performance?
    • Is the error or deficiency due to poorly designed or inappropriate equipment?
    • Is the error or deficiency due to inadequate strength?
Instruction
  • Communicate with the performer
  • Correct the error
Repeat the analysis

Example analyses
Fastball in baseball
Forehand drive in tennis
Sprint running
