• Numerical
• Meaningful
• E.g. multi-stage fitness test, vertical jump

Question 4

Describe subjective data

Answer 4

• Qualitative
• Based upon personal opinion
• Assumptions
• Emotions/interpretations
• E.g. Borg scale (RPE)

What is match analysis?

Answer 8

• Used to record aspects of individual or team performance

Question 9

What is biomechanics?

Answer 9

• Used to analyse the sporting impact of body movements

Question 10

What are the benefits to using motion analysis? (9 points)

Answer 10

1 - Quantitative analysis
2 - Accurate
3 - Reliable and valid
4 - Tells athlete what happened (as oppose to what they think)
5 - Aid performance enhancement/maximise performance
6 - Wide range of techniques available
7 - Undertaken in training or match situations
8 - Immediate feedback
9 - Allows for new goals to be set

Question 11

Name 3 examples of match analysis

Answer 11

1 - Dartfish
2 - Upmygame
3 - Prozone

Question 12

Define the term research

Answer 12

Investigation/study aimed to improve performance

Question 13

Define the term reliability

Answer 13

• Repeatable

- Comparable

Question 14

Define the term valid

Answer 14

The test measures what it sets out to

Question 15

What are the advantages of video analysis?

Answer 15

• Collects quantitative data
• Done in match situations
• Visual/verbal feedback is immediate
• Allows smarter targets to be set

Question 16

What does GPS stand for?

Answer 16

Global Positioning System

Question 17

How does a GPS work?

Answer 17

Uses satellites that provides location and time information meaning it can track:
- Speed 
- Distance
- Direction
- Heart rate
Then these can be used to measure:
- Acceleration
- Time spent in each HR training zone
- Recovery

Question 18

How is GPS/motion tracking beneficial for a sports performer?

Answer 18

• Can help injured players with rehabilitation
• Can tailor training to match needs
• Collects quantitative data
• Coaches can use to monitor players in training/matches - helps improve player performance

Question 19

What is a metabolic cart?

Answer 19

A machine that measures the volume of oxygen inhaled and the volume of carbon dioxide exhaled - this is done by an athlete breathing through a tube and a computer analyses the gases

Question 20

When can a metabolic cart be used?

Answer 20

Either at rest or during exercise

Question 21

What are the benefits of using a metabolic cart?

Answer 21

• Can calculate calories burned - meaning it can then give accurate nutritional information (this is called indirect calorimetry)
• Can calculate how much oxygen (and so calories) needed at rest (this is called resting energy expenditure (REE))

Question 22

What are the disadvantages of using a metabolic cart?

Answer 22

• Expensive
• Not always accurate
• Information is only a ‘snapshot’

Question 23

What is data integrity?

Answer 23

Ensuring data is accurate and consistent over its entire lifetime

Question 24

How can data integrity be achieved?

Answer 24

Recorded as intended and when retrieved is same as original

Question 25

What are the risks of data integrity?

Answer 25

Can be compromised by human error/software bugs and viruses

Question 26

How can the risk be minimised?

Answer 26

• Backing up

- Restricting access
