Answer 6

angle of segment

Question 7

Answer 7

running and cycling

Question 8

list 3D multi-planar movements

Answer 8

throwing, pitching, golf swing, tennis se

Question 9

what is a degree of freedom

Answer 9

number of directions a body and joints can move

Question 10

what are the strengths of qualitative movement analysis

Answer 10

• no expensive equipment
• field tests= increased ecological validity
• if done properly will be highly systematic
• coach and athlete-friendly

Question 11

what are the weaknesses of qualitative data

Answer 11

• lack of data
• need considerable knowledge of the movement
• reliability and validity are questionable = observer bias

Question 12

what are the strengths of quantitative analysis

Answer 12

• quantitative of biomechanical data
• reliability and objectivity can be easily assessed

Question 13

what are the weaknesses of quantitative data

Answer 13

• expensive equipment
• lab test
• lack of theoretical knowledge can be masked by data driven approach
• not coach friendly

Question 14

balance

Answer 14

control of position relative to the base of support

Question 15

co-ordination continuum

Answer 15

timing of muscle action and segment motions

Question 16

force- motion

Answer 16

unbalanced forces acting on a body to create movement

Question 17

inertia

Answer 17

resistance to motion

Question 18

range of motion

Answer 18

range of motion used to complete the action

Question 19

segmental interaction

Answer 19

proximal to distal sequencing, summation of force

Question 20

force-time

Answer 20

magnitude of force and duration of application affect the resulting motion

Question 21

optimal projection

Answer 21

projection angle optimised for task

Question 22

spin

Answer 22

lift force, affects trajectory of ball and other projectiles

Question 23

what are the 4 fundamental stages of movement analysis

Answer 23

• stage 1: preparation phase
• stage 2: observation stage
• stage 3: evaluation and diagnosis
• stage 4: intervention

Question 24

what are the main objectives of the preparation phase

Answer 24

• gathering knowledge
• conduct needs analysis
• know activity inside and out
• establish critical features
• develop systematic observation strategy
• in-depth knowledge of physical and cognitive characteristics of perfromers
• develop initial intervention strategy

Question 25

what are the main objectives of the observation stage

Answer 25

• gathering information about movement from the senses and from video recording
• focus of observation = phase of movement
• observe in controlled environment
• observe from vantage points
• number of observations
• other procedural issues for recording movement

Question 26

what are the main objectives for the evaluation and diagnosis stage

Answer 26

• evaluating strengths and weaknesses of performance
• diagnosing what weakness to tackle
• prioritising intervention to improve perfromance

Question 27

what are the main objectives of the intervention stage

Answer 27

• administering feedback and correction to improve performance
• emphasise feedback to perfromers to improve technique and perfromance
• main view of the whole process in context of needs analysis from prep stage
