Question 1

Skill Strength: Heel recovery in the first few steps (Technique)

Answer 1

They do not flick their feet behind them so they have a more efficient leg action as they can bring their leg through faster and bring their knee higher.

Question 2

Skill Strength: Heel recovery in the first few steps (Impact on Performance)

Answer 2

This improves the overall success as it allows the performer more efficiently and regularly apply power to the floor which will push them down the track faster meaning they will place higher in the race.

Question 3

Skill Strength: Heel recovery in the first few steps (Link to theory)

Answer 3

This may be because she has higher levels of confidence at the start of the race meaning her arousal levels will be at an optimum level to maximise her performance at that point in time.

Question 4

Skill Strength: Upright posture during the race (Technique)

Answer 4

They remain fairly upright throughout the race which allows more space for her to bring her knees higher.

Question 5

Skill Strength: Upright posture during the race (Impact on performance)

Answer 5

Overall, this allows the performer to apply more force to the floor with each step which will propel her forwards more, allowing her to finish the race faster and place higher.

Question 6

Skill Strength: Upright posture during the race (Link to theory)

Answer 6

…

Question 7

Skill Strength: Fast turnover with legs (Technique)

Answer 7

She was able to run with a fast frequency of steps which allows her to create contact with the floor more regularly.

Question 8

Skill Strength: Fast turnover with legs (Impact on performance)

Answer 8

Overall, this allows her to apply more force to the floor more regularly which will increase the forward momentum and increase her chances of placing higher in the race.

Question 9

Skill Strength: Fast turnover with legs (Link to theory)

Answer 9

This may be because she has a large number of type 2b muscle fibres in her glute muscles and iliopsoas. This means these muscles will contract quickly and regularly with more force which is why her legs will move faster.

Question 10

Fitness Strength: Reaction to the gun (Technique)

Answer 10

She moved out of the blocks very quickly and remained in line with the rest of her competitors.

Question 11

Fitness Strength: Reaction to the gun (Impact on performance)

Answer 11

This meant that she did not lose ground and start the race behind the rest of the field which gives her a better chance of placing higher in the race.

Question 12

Fitness Strength: Reaction to the gun (Link to theory)

Answer 12

This is likely down to her having strong stimulus-response bonds. After hearing the gun, the information is received and processed quickly and the motor units going to the leg muscles are efficient at initiating an immediate response allowing her to move without hesitation.

Question 13

Skills weakness: Arm position in blocks (technique)

Answer 13

arms are too wide so torso is closer to the ground so less room for legs to come through

Question 14

Skills weakness: Arm position in blocks (impact)

Answer 14

moves up rather than forwards so loses forward momentum so is further behind competitors

Question 15

Skills weakness: Arm position in blocks (theory)

Answer 15

gluteus maximus contracts before posterior and anterior deltoid so first movement is up rather than arm splitting forwards.

also increases stability due to increased base of support so greater inertia

Question 16

skills weakness: drive phase (technique)

Answer 16

up after three steps so loses forward momentum so does not reach max speed

Question 17

skills weakness: drive phase (impact)

Answer 17

not at max speed so competitors pull away and she places lower in the race

Question 18

skills weakness: drive phase (theory)

Answer 18

Newton’s second law states that acceleration is in the same direction as and proportional to the size of the force acting on it. if she applies less forward force due to ending drive phase early, her acceleration will not be as great as it could be

Question 19

skills weakness: knee drive (technique)

Answer 19

second half of race knees drop and not getting full range of stride. stride stops before knee is in line with hips and femur is parallel to the floor.
