Technology Flashcards
What is the aim of using technology in sport?
Improve performance and results
What are the two types of data?
Qualitative and quantitative
Describe objective data
- Quantitative
- Based upon facts and is measurable
- Numerical
- Meaningful
- E.g. multi-stage fitness test, vertical jump
Describe subjective data
- Qualitative
- Based upon personal opinion
- Assumptions
- Emotions/interpretations
- E.g. Borg scale (RPE)
Define validity
When the test actually measures what it sets out to do
Define reliability
The test can be repeated accurately
Describe video motion analysis
- Involves high-speed camera and computer with software
- Used to identify and correct problems
What is match analysis?
- Used to record aspects of individual or team performance
What is biomechanics?
- Used to analyse the sporting impact of body movements
What are the benefits to using motion analysis? (9 points)
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
Name 3 examples of match analysis
1 - Dartfish
2 - Upmygame
3 - Prozone
Define the term research
Investigation/study aimed to improve performance
Define the term reliability
- Repeatable
- Comparable
Define the term valid
The test measures what it sets out to
What are the advantages of video analysis?
- Collects quantitative data
- Done in match situations
- Visual/verbal feedback is immediate
- Allows smarter targets to be set
What does GPS stand for?
Global Positioning System
How does a GPS work?
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
How is GPS/motion tracking beneficial for a sports performer?
- 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
What is a metabolic cart?
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
When can a metabolic cart be used?
Either at rest or during exercise
What are the benefits of using a metabolic cart?
- 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))
What are the disadvantages of using a metabolic cart?
- Expensive
- Not always accurate
- Information is only a ‘snapshot’
What is data integrity?
Ensuring data is accurate and consistent over its entire lifetime
How can data integrity be achieved?
Recorded as intended and when retrieved is same as original
What are the risks of data integrity?
Can be compromised by human error/software bugs and viruses
How can the risk be minimised?
- Backing up
- Restricting access
