EAPI (note form)

Question 1

3 skill strengths

Answer 1

• heel recovery on first few steps
• good posture during race
• fast turnover with legs

Question 2

1 tactic strength

Answer 2

• does not slow down to conserve energy

Question 3

1 fitness strength

Answer 3

• reaction time

Question 4

develop heel recovery as a strength

Answer 4

• feet do not flick behind
• more efficient
• knee higher faster
• level with field for first 10/20m

Question 5

heel recovery theory

Answer 5

• increase/maintain confidence
• no over-arousal
• using ATP-PC system to full potential

Question 6

develop good posture as a strength

Answer 6

• knees can come higher
• more force applied to floor
• propel forwards so finish faster

Question 7

posture theory

Answer 7

• Newton’s 2nd law - acceleration
• more force applied = more acceleration

Question 8

develop fast turnover as a strength

Answer 8

• apply force more regularly
• increases forward momentum
• increased chances of placing higher

Question 9

fast turnover theory

Answer 9

• type 2b muscle fibres in glutes and iliopsoas
• faster and more force of contraction

Question 10

develop not slowing down as a strength

Answer 10

• many athletes will slow down to conserve energy
• does not as not getting to next round
• more chance of getting to next round

Question 11

not slowing down theory

Answer 11

• does not get over-aroused
• changes plan to ensure best chances of getting to next round

Question 12

develop reaction time as a strength

Answer 12

• goes straight away
• does not lose ground against competitors
• places higher at start of race

Question 13

reaction time theory

Answer 13

• strong s-r bonds
• efficient motor units
• response is quick

Question 14

5 skill weaknesses

Answer 14

• arm position in blocks
• drive phase
• arm drive
• knee drive
• foot kicking out

Question 15

1 tactic weakness

Answer 15

• no dip on line

Question 16

2 fitness weaknesses

Answer 16

• muscular endurance
• power/strength

Question 17

develop arm position in blocks as a weakness

Answer 17

• arms too wide
• torso too low
• first movement is up not forwards
• loses ground against competitors

Question 18

arm position in blocks theory

Answer 18

• gluteus maximus contracts before posterior and anterior deltoids
• also greater stability due to greater base of support so greater inertia

Question 19

develop drive phase as a weakness

Answer 19

• up after 3 steps
• loses forward momentum
• does not reach max speed
• competitors can overtake and pull away

Question 20

drive phase theory

Answer 20

• less acceleration means less change in velocity
• slower final velocity

Question 21

develop arm action as a weakness

Answer 21

• not fully driving in 2nd half
• so legs do not fully drive
• less force on floor
• not as powerful as competitors

Question 22

arm action theory

Answer 22

• deltoids not fully contracting
• no full flex/ext
• bilateral coordination so legs do not either
• due to poor muscular endurance

Question 23

develop knee drive as a weakness

Answer 23

• stride stops before parallel with floor
• less force
• won’t go forwards as fast as competitors

Question 24

knee drive theory

Answer 24

• incorrect dominant response when competitors begin to overtake
• could be a cognitive or associative learner

Question 25

develop foot kicking out as a weakness

Answer 25

- leg extends before foot hits floor - foot contacts ground in front not below - slows down so finishes slower than competitors

Question 26

foot kicking out theory

Answer 26

- force applied forwards not back - friction back not forwards - overall force is back so slows down performer

Question 27

develop not dipping as a weakness

Answer 27

- did not dip/lean forward on the line - crosses line after other competitors if close to them

Question 28

not dipping theory

Answer 28

- could be frustrated so did not dip - due to over-arousal - could have led to aggression based on frustration-aggression hypothesis

Question 29

develop muscular endurance as a weakness

Answer 29

- loss of technique in second half of race - muscles got tired - poor anaerobic fitness - competitors catch up an overtake her to beat her

Question 30

muscular endurance theory

Answer 30

- glycolytic system dominant after 10secs - glycolytic energy system not efficient - not enough ATP produced

Question 31

develop power/strength as a weakness

Answer 31

- not applying enough or effectively - muscles contract with less force - other competitors move forwards faster due to more force on floor

Question 32

power/strength theory

Answer 32

- less type 2b fibres - high speed/force of contraction - due to high PC stores - will not use as much force if does not have these
