Q

How can video analysis be used

A

A high speed camera films the performer. The footage is then able to be watched back using a computer software that allows frame by frame playback of the footage on video
This can allow technique or group performance to be viewed

Q

What is indirect calorimetry

A

The measurement of the amount of heat/energy generated in an oxidation reaction by determining the intake or consumption of O2 or the amount of CO2 released and translating those quantities to the heat equivalent

Q

Advantages of indirect calorimetry

A

Helps to determine energy requirements and response to nutrition
Can calculate energy expenditure to determine nutritional needs
Helps classify people in to categories - eg obese
Helps medical staff determine amounts of food and nutrition needed as RE can be calculated

Q

Disadvantages of indirect calorimetry

A

Inaccuracies from air leaks
Difficult to use on children
Overfeeding/underfeeding may occur based on results received
The process measures consumption not needs

Q

What does GPS stand for

Study These Flashcards
A

Global positioning system

21
Q

What information can be tracked by GPS for an elite performer

Study These Flashcards
A

Speed, heart rate, G force, distance, dynamic acceleration, direction, recovery time and success rates in technical perfromance

22
Q

What information can be tracked by GPS for an everyday performer

Study These Flashcards
A

Tracks and monitors times, distances, routes and elevation

23
Q

Why use GPS for player performance tracking

Study These Flashcards
A

Makes better use of training time
Improves tactical analysis undertaken at a club
Helps injured players get through rehab faster
Helps a coach compare player performance and pick the best squads

24
Q

What is data integrity

Study These Flashcards
A

Maintaining and ensuring the accuracy and consistency of stored data over its entire lifetime

25
How can data integrity be compromised
Human error when entering data Software bugs/viruses Hardware malfunction such as disk crashes Errors occurring when data is transmitted from one computer to another Leaving devices unlocked or unattended
26
How can we minimise threats to data integrity
Regularly backing up data Controlling access to data Using error detection and correction software when backing up data Not leaving devices unattended Designing interfaces which prevent the input of invalid data/taking care when entering data Limiting the amount of times data is shared/transferred
27
How can sports analytics be used to improve performance
Monitoring fitness for performance Skill and technique development Injury prevention Game analysis Talent ID/scouting
28
What is vibration technology
Whole body therapy involving whole body vibration using vibration plates to induce exercise effects on the body
29
What can vibration technology do
Increase bone density and muscle mass/power Improve circulation Reduce joint pain Boost metabolism Reduce the effects of DOMS Reduce back pain Alleviate stress
30
What is electrostimulation
Production of muscular contraction through the use of electrical impulses
31
What can electrostimulation do
Increases muscle, power and strength Reduces recovery times and assist rehabilitation Promotes blood circulation in the body/stimulates muscles to promote blood Prevents losses in fitness when injured Reduces amounts of lactic acid produced following training
32
What are the advantages of notational match analysis
Provides objective data and removes subjectivity from performance providing factual insight Identifies strengths and weaknesses Informs tactical decisions - coaches can use data to adjust formation, strategies and positioning Tracks player performance overtime Improves coaching feedback
33
What are the disadvantages of notational match analysis
It is time consuming to collect and analyse large amounts of data Requires specialist equipment & software and relies on expensive equipment Data can be overwhelming - too much information can make it difficult to focus on key performance aspects Relies on accurate input for analysis to be reliable May not account for contextual factors
34
What are the advantages of biomechanics
Provides athlete with visual feedback Enhances performance analysis - can identify things that may not be visual in real time Injury rehabilitation and prevention - helps to detect improper technique leading to injury and tracks recovery process Allows slow motion and frame by frame review Improves technical development Tracks progress overtime
35
What are the disadvantages of biomechanics
Expensive equipment and software Time consuming to review footage Requires specialist knowledge to interpret data correctly Environmental factors can affect accuracy - eg lighting or angles Athletes may feel self conscious
36
What are the negatives of technology for the coaching/analysis department
Lots of data overloads the department Unable to understand or analyse all of the data collected There can be a reliance on data so it becomes less about the coach's knowledge Data does not always show a true reflection of performance - eg GPS may show a lack of movement but this does not mean performance is ineffective Data is unreliable if outdated
37
What are the positives of technology for the audience
Playback of decisions on a large screen Officials can be heard More accurate decisions Increased excitement/anticipation for the decision Fairer outcomes Cheating is removed Home experience improved - more camera angles Wider access to all sports so more understanding of them
38
What are the negatives of technology for the audience
Traditionalists against the idea of change Could get boring/time consuming for the viewer Increased watching = decreased participation Decreased atmosphere at games
39
What are the positives of technology for the spectator (AO1 & AO2)
AO1 Improved knowledge of sport, nutrition and fitness Improved facilities to train in Helps to prevent injury Can analyse their performance AO2 Improved performance overall so higher chance of success More records broken Perform more frequently Better accuracy when making their own decisions
40
What are the negatives of technology for the spectator
Improved performance = heightened expectations so more pressure Technology is expensive Performers become more popular which could reduce career length
41
What are the positives of technology for the officials
Ensures correct decisions are made - less controversy Helps communication between officials Less pressure on officials as technology can make the final decisions Can be quick and efficient
42
What are the negatives of technology for the officials
Technology can still be wrong Over reliance on technology Nature of the sport has changed, the officials can be 2nd in command to technology Expensive Breaks in play can cause disruptive behaviour towards officials
43
How has equipment developed
Equipment can now be adapted for disability and age
44
Examples of how equipment has developed for disabled people
Prosthetic limbs Specially designed wheelchairs Sit down skis
45
Examples of how equipment has developed for the elderly
Low impact pedal machine stimulates circulation Exercise balance beam improves/maintains balance
46
How have facilities developed
There are improved standards and technology in matches and stadiums
47
Examples of how facilities have developed
3G & 4G surfaces mean sports like football and hockey can be played more frequently Multi use game areas (MUGAs) can be used to save money and increase participation Adapted facilities such as ramps, lifts, hoists and adjustable floors make venues inclusive
48
What is Olympic legacy
An initiative created by Sport England who's aim it is to increase participation by providing facilities for local communities
49
What is 'iconic facilities' part of and what does it do
It is part of the Olympic legacy initiative by Sport England It directs funds to increase mass participation in sport across England
