1

Name their skill strengths

Reaction time, angle out of the blocks and foot placement

2

Name their skill weaknesses

Poor arm action, posture and slow cadence

3

Name their tactical strengths

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

4

Name their tactical weakness

Pacing of their maintenance phase

5

Name their CoF strengths

Speed and muscular strength

6

Name their CoF weaknesses

Power and muscular endurance

7

Reaction time

- 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)

8

Angle out of the blocks

- 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)

9

First foot placement

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

10

Arm action

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

11

Posture

- 'Posterior chain'
- Abdominals, gluteus, vertebrae, pelvic girdle
- Dipped headlights

12

Knee lift

- Type three lever system
- Looped leg action
