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
