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
What is data integrity?
Ensuring data is entered into system and recorded exactly as intended
How can data integrity be compromised?
- Human error
- Errors from computer to computer
- Software bugs or viruses
- Hardware malfunctions
How can threats to data integrity be minimised?
- Regularly backing up data
- Controlling access to data
- Using error detection and correction software
- Not leaving a computer unattended
What are some health benefits of application vibration therapy/electrostimulation?
- Improve bone density
- Increasing muscle mass
- Improving circulation
- Reducing joint pain
- Alleviating stress
- Boosting metabolism
- Overall reduction in pain/DOMS
How does electrostimulation work?
- Strengthens and tones the muscles to prevent injury
- Prevent losses in fitness levels via application to specific muscle groups
- Helps get rid of lactic acid after a training session or competition
What is the use of analytics in talent ID/Scouting?
- Can be used to provide qualitative data of individual performers
- Through written scouting reports on opposition players and feedback of players being watched
- Technology can be used in pathway analytics as a method of systematically profiling the effectiveness of performance pathways
- Talent ID programmes have been developed over years to meet requirements of different sports/roles such as tall and talented for basketball
What are the advantages and disadvantages of talent ID and scouting?
+ Can identify good links
+ Easy to transfer
- May link characteristics but not skills/ability
What are the benefits and problems of 3G artificial grass?
+ Range of sports
+ High levels of use
+ More frequent use
+ Predictable
- Not reflective of grass
- Potential higher chance of injury
How can equipment/facilities be adapted for elderly people with the use of technology?
- Low impact pedal machine
- Balance beam
- Technologically advance wheelchair designs if needed
What are some assistive devices to help disabled people with the use of technology?
- Lightweight wheelchairs for basketball, tennis and road racing
