The Role of technology in Physical Activity and Sport Flashcards
Define research and sports analytics
Research - A systematic process of investigation and study carried out with the aim of advancing knowledge
Sports Analytics - Studying data from sports performances to try and improve performance
What is OPTA, and how can it be used in elite sport?
A company with statisticians gathering and analysing sporting data collected in order to create the best predictions of sporting outcomes as possible
- Optimise performance
- Detailed analysis of opponents
- Effective recruitment of new talents
What is validity and reliability?
Validity - How much data collected actually measures what it claims to measure
Reliability - How consistent data is and how similar results are when the process is repeated
Describe kinematics and explain how it can improve performance
- Performer has sensors on joints and often muscles
- They are filmed, usually in a lab but sometimes of a track/pitch
- Data on their joint movement can help improve technique, power and speed
- Helps athletes recover from injury and avoid bad habits in technique
What is notational match analysis?
- Eg heat maps
- Quantitative data
- Movement patterns, strategy and tactics objective data gathered
- Through video and GPS tracking
What are biomechanics?
- Analyses sporting impact of body movements
- Quantitative, based study and analysis of sports activities
How much of a performance is recalled from memory, and from performance analysis?
Memory - 30%
PA - 100%
What are the advantages and disadvantages of video performance analysis?
+ More accurate/objective
+ Evidence
+ Replay
+ Not reliant on memory
+ Scientific
- Questioning coach/ref professionalism
- Evidence of misconduct
- Equipment issues
- Validity of testing
- Reliability of results
What is indirect calorimetry?
- Technique where headgear is attached to someone while they breathe for a specific amount of time
- Volumes and concentrations of CO2 and O2 are measured, and translate into a heat equivalent
- Provide a result for the metabolic cart
What is the metabolic cart measured in?
Resting energy expenditure (REE)
What is calorimetry?
The measurement of the heat and energy eliminated or stored in any system
What are the advantages and disadvantages of indirect calorimetry and a metabolic cart?
+ To determine energy requirements
+ To calculate energy expenditure
+ Who are classified as obese
- Inaccuracies from air leaks
- Inaccuracies from measurement or recording errors
- Difficult to use on children
- Overfeeding/underfeeding may occur
- Single snapshots are worse than average results
What is GPS?
Global positioning system - Software tracking systems help coaches monitor players during training/matches and can track information
What can GPS track?
- Speed
- Distance
- Direction
- G Forces (impacts and forces)
What are the advantages and disadvantages of GPS tracking?
+ Improves performance via monitoring
+ Provides objective decisions regarding players
+ Better use of training to meet game demands
+ Improve tactical awareness
+ Help select best in form players
+ Avoid players getting injured/quicker recovery
- Can be expensive
- Reliability
- Use in the correct way
- Overload of information
