Week 3

Question 1

Two types of movement analysis

Answer 1

Qualitative & Quantitative

Question 2

Qualitative

Answer 2

Implies that description of motion is done without the use of numbers

Question 3

Quantitative

Answer 3

Implies that description is made with numbers

Question 4

Advantages of quantitative approach

Answer 4

Measures magnitude
Detect small changes in motion
Objective feedback
Detailed information

Question 5

Disadvantages of the quantitative approach

Answer 5

Expensive
Can be highly sophisticated
Mathematical

Question 6

Advantages of qualitative approach

Answer 6

Freely available
Quick, easy, simple
Cheap

Question 7

Disadvantages of qualitative approach

Answer 7

Requires good background knowledge/experience
Subjective
Difficult to track movement

Question 8

Most analysis of athletes/activities is done via this approach

Answer 8

Qualitative

Question 9

Describe a movement pattern

Answer 9

a general series of anatomical
movements that have common elements
of spatial configuration

e.g. Walking, running, jumping, lifting, kicking

Question 10

Describe a skill

Answer 10

when a general movement pattern is
adapted to the constraints of a particular
task or sport

e.g. high jump, tennis backhand

Question 11

Describe technique

Answer 11

when a particular type of the same skill is performed

Question 12

Describe style

Answer 12

individual adaptations to a technique

Question 13

Two classifications of a skill

Answer 13

Closed and Open skill

Question 14

What is a closed skill

Answer 14

Performed in a predictable environment

e.g. tennis serve

Question 15

What is an open skill

Answer 15

Skill is performed in and in response to an unpredictable, changing environment

e.g. tennis return

Question 16

What is a discrete skill

Answer 16

Defined beginning and end, able to divide into separate phases

e.g. cartwheel

Question 17

What is a continuous skill

Answer 17

No defined beginning or end, repeated cycles of same movement

e.g. cycling, running, walking

Question 18

Serial discrete skill

Answer 18

Same as discrete skill, but multiple done in a row

e.g. multiple backflips in a gymnastics routine

Question 19

Phases of discrete skill

Answer 19

1. Preparation
2. Movement / Execution
3. Recovery / Follow-through

Question 20

Phases of a continuous skill

Answer 20

Each cycle performed in the same way so we pick and analyse ONE representative cycle and divide that cycle into separate phases

Question 21

Steps in analyzing movement (4)

Answer 21

Preparation
Observation
Evaluation/diagnosis
Intervention

Question 22

Preparation stages (5)

Answer 22

1. Identify the Overall Performance Objective (OPO) or Goal
   of the skill 2. Divide skill into discrete parts  Detail each part 3. Identify the mechanical purpose (MP) of each discrete
   part to achieve the OPO
2. List the biomechanical factors (BF) of each discrete part
   that enable the accomplishment of the MP
3. List the critical features (CF)

Question 23

Describe the importance of the observation stage of analysing a movement

Answer 23

How we are recording or looking at the event. The angle, distance and height we are filming from. Frame rate is important to capture the event in slow motion.

Question 24

Evaluation stage

Answer 24

Judge quality of movement, assess good and bad points, critique against ‘norm’ and ‘elite’ performance and address cause of error

Question 25

Intervention stage

Answer 25

Selection of most appropriate intervention and should provide good feedback
