S2-Lab 4- Qualitative Approach- Movement Analysis

Question 1

What is the six step approach for gathering evidence when it comes to a qualitative approach?

Answer 1

1. Determine the objective of the skill
2. Note any special characteristics of the skill
3. Study top-flight (elite) performances of the skill
4. Divide skill into phases
5. Divide each phase into key elements
   6.Understand the mechanical reasons for each element

Question 2

When employing a qualitative approach, it is useful to understand the possible and main “constraints of movement”

Answer 2

• Movement pattern
• Skill
• Technique
• Style
• Rules and Environment
• Human constraints- strength, power, endurance, speed , flexibility.

Question 3

Step 1- Determine the objectives of the skill-

Answer 3

Identify these and look for an OPO

= Overall Performance Objective

This can be broken down into primary and secondary objectives

Question 4

Step 2- Note any special characteristics of the skill

Answer 4

Is the skill open/ closed

Is the skill discrete/ continuous

Question 5

Step 3- Study a top-fight (elite) performance of the skill

Answer 5

Look at the skills demonstrated and factors that might constrain movement

Constraints of movement- skill, technique, movement pattern, style, rules and environment, human factors- strength, power, endurance

Question 6

Step 4- Divide into key phases

Answer 6

3 main phases

PREPARATORY

EXECUTION

RECOVERY

Question 7

Step 5- Divide into key elements- those between the key phases

Answer 7

Looks at the main aspects of each stage and allows you to indicate where you think the transitions are.

Question 8

Step 6- understand the mechanical reasons for each element

Answer 8

Human factors-
“lower kinetic chain”
-turning force
-power
-technique
