Answer 3

Timing of the dip over the line and length of their acceleration phase

Question 4

Name their tactical weakness

Pacing of their maintenance phase

Question 5

Name their CoF strengths

Answer 5

Speed and muscular strength

Question 6

Name their CoF weaknesses

Answer 6

Power and muscular endurance

Question 7

Reaction time

Answer 7

• Important because there are often milliseconds between finishes and so they need to reduce time wasted but also need to make a first foot placement quickly
• Technology in sport (2016/1996 Olympics)

Question 8

Angle out of the blocks

Answer 8

• 45 angle enables efficient knee lift
• Controlled execution from the blocks (too low increases effort and too high reduces acceleration phase)
• Newton’s third law (relate to force produced by the knee)

Question 9

First foot placement

Answer 9

• Low above the floor
• Didn’t lose momentum
• Too far in front = lose power
• Too short = more effort

Question 10

Arm action

Answer 10

• Co-ordinates leg action
• Flexion and extension of the elbow
• Movement analysis
• Somatic arousal too high
• Inverted U theory

Question 11

Posture

Answer 11

• ‘Posterior chain’
• Abdominals, gluteus, vertebrae, pelvic girdle
• Dipped headlights

Question 12

Knee lift

Answer 12

• Type three lever system

- Looped leg action
