- measurable
- useful for making decisions based on performers strengths and weaknesses
- Eg/ performance analysis of a swimmer
7
Q
What is subjective data?
A
- information based on opinions, emotions and beliefs
- less measurable
- emphasis on personal opinion
- less suitable when providing feedback
- Eg/ parents telling child at halftime their opinions

+ helps medics determin the amount of food and nutrition needed
- can be innaccuracies from air leaks
- could be innaccuracies from recording errors
- difficult using it with children
- can cuase possible over or under feeding
- single snapshot rather than average result over longer period of time

Why is GPS tracking used in sporting situations?
- monitors players during matches and training
- computer based information about speed, distance, direction and G forces
- helps to improve performance by monitoring success rates
- meaures G force in high contact sports
- helps caches make coices about substitutions which decreases risk of injuries
27
How does GPS tracking help player performance?
- more efficient use of training time
- ensures training meets demands of the game
- improves tactical analysis

28
What is data integrity?
The maintenance of accuracy and consistency of stored data over its entire lifetime
29
How can data be compromised?
- human error when data is inputted or misinterpreted incorrectly
- human error when data is entered
- errors when data is transfered from one computer to another
- software affected by virus
- hardware malfunction
- computer left unsupervised so vulnerable to be tampered with
- data not saved securely so could have been altered
30
What are the ways to minimise threats to data integrity?
- back up data regularly

32
How does monitoring fitness for performance help to increase chances of success?
- helps to gain information to help in monitoring fitness for performance
- individual recreational purposes (heart rate or calories)
- elite sport purposes (distance covered, , sleep statistics, calorie input and output)
- usually tracked by small wearable fitness devices
33
How does skill and technique development help to increase chances of success?

47
48
What is the impacts of technology on the coaches?

50
What are the impacts of technology on the audience?
+ increased knowledge of the sport (replays and match analysis)
+ increased excitement and involvement (VAR)
+ ensures right decisions being made (less frustration on incorrect decisins)
+ more accurate data on timing and distances achieved (quickly shown on scoreboard)
+ helps officials communicate with eachother and players which audience can also hear
- loss of respect for officials
- cost can limit use of tech (inconsistent experience)
- breaks in play disrupt flow of the game (advertisments)
