The role of technology in physical activity and sport Flashcards
Sport analytics
Studying data from sport performances to try and improve performances
Eg. Moneyball
Functions of Sport analytics (5)
- Monitor fitness
- Skill and technical development
- Injury prevention
- Game analysis
- Talent ID
Quantitative data
Numerical data
Qualitative data
Non-numerical data
Reliability
Whether procedures have been followed the same way each time they’re repeated to enable similar results
Validity
Whether what is being claimed to be tested is actually what is being tested
Objective
Measures what you want to
Quantitative
Subjective
Personal opinion based
Qualitative
Analytics
Systematic approach to gathering data
Data collective
- Technology is used in data collection
- Video and analytics packages including Dartfish/Prozone
- Include objective facts and provide evidence for subjective appraisal
- Include high speed camera (GPS) stats
Video motion analysis
A technique used to get information about moving objects from video
What are the two types of Video motion analysis
- Notational match analysis
- Biomechanics
Notational match analysis
Used to record aspects of individual/team performance, such as movement patterns, strategy and tactics. Obtains objective qualitative data
What are two types of notational match analysis
- Dartfish
- Prozone
Biomechanics
- Used to analyse the sporting impact of body movements
- Quantitative based study
- Kinematics
- Sensors on their joints and often muscles of the body
- Filmed performing skill often in a lab
- Injury prevention
Performance analysis
The provision of objective feedback to performs trying to get a positive change in performance
Indirect calorimetry
The measurement of the amount of heat and energy generated in an oxidation reaction
Calorimetry
The measurement of the heat and energy eliminated or stored in any system
Metabolic cart
A device which works by attaching headgear to a subject while the person breathes a specific amount of oxygen over a period of time
Resting Energy Expenditure (REE)
The amount of energy, usually expressed in Kcal, required for a 24 hour period by the body during rest
What can Indirect calorimetry and use of a metabolic cart can help individuals to do
- Determine energy requirements and response to nutrition
- To calculate energy expenditure
- Who are classified as obese
- Calculation of REE
What are the potential difficulties affecting validity and reliability using indirect calorimetry via a metabolic cart
- Inaccuracies from air leaks
- Possible inaccuracies from measurements
- Difficult to use on children
- Overfeeding or underfeeding may occur
- Singe snapshots are worse than average results over a longer period of time
- The process actually measures consumption, not needs
Computer software
Computer software is any set of machine-readable instructions which direct a computer’s processor to perform specific operations
Computer hardware
Computer hardware is the physical components of computers
‘G’ forces
Forces acting on the body as a result of acceleration or gravity e.g. G-load/force of an American football ‘hit’ on an opponent
What does GPS stand for
Global Positioning System
GPS
A space based navigation system that provides location and time information
Benefits of GPS technology for player tracking
Data integrity
Maintaining and ensuring the accuracy and consistency of stored data over its entire lifetime
How can data integrity be compromised
Ways to minimise threats to data integrity
Smart device
Worn or attached to performers body while in use to provide instant feedback on aspects of performance such as distance covered, HR etc
Two ways analytics can help in injury prevention
- Vibration technology
- Electrostimulation
Vibration technology
Vibration training/therapy is also known as whole body vibration and a example of its usage involves the use of vibration plates to induce exercise effects in the body
Electrostimulation
The production of muscle contraction using electrical impulses
What technological devices are used in injury rehab
Facility improvements
3G surfaces
Third generation artificial synthetic grass pitches
Game Golf
A lightweight GPS tracking device which captures accurate shot locations and calculates club performance during a round of golf
Compression garments
Items such as elasticated leggings, socks, shirts worn to promote recovery by improving circulation
Positives of technology in sport
+ Improved detection of doping with modernised testing devices
+ More accurate decision making allowing for fairer results
+ Better timing devices and increased recording of performance
+ Improved detection of foul play e.g. VAR/TMO
+ Improved quality of performance
Negatives of technology in sport
- Access to modern technology can be limited
- More accessible to sports which are more financially secure
- Increased pressure on officials to make correct decision
- Performance Enhancing Drugs testing cannot keep up with new drugs developed
Positives if technology for the performer
+ Improved performance levels
+ Improved fitness testing
+ Improved training facilities and equipment
+ Improved analysis of performance
Negatives of technology for the performer
Positives of technology for the audience
Negatives of technology for the audience
Positives of technology for the coach
Negatives of technology for the coach
