The role of technology in physical activity and sport Flashcards
What is research ?
A systematic process of investigation and study carried out with the aim of advancing knowledge
What are sports analytics ?
Studying data from sports performances to try and improve results
How are sports analytics used ?
- used across the majority of sports through the world
- gives coaches and managers details on strengths and weaknesses
- A company called Opta specialise in sports analytics and sports such as football and cricket use these platforms to fine-tune and optimise performance
- Technology in sports collects different types of data
- Need to ensure data is reliable, valid and objective
What is quantitate research ?
- formal, objective and systematic process
- factual and numerical data
- e.g. most fitness tests
What is qualitative research ?
- focuses on words
- subjective
- uses thoughts and emotions
- helps gain a better understanding on participant experiences
What is objective research ?
- information received based on facts
- measurable and observable
- suitable for feeding information back to the performer
What is subjective research ?
- information based on personal opinions, assumptions and emotions
- seen as less meaningful feedback for a player
What is validity ?
How much the data actually measured what it set out to do
What is reliability ?
How consistent results are when using the same process
What are video and analysis programmes ?
- coaches and athletes are using technology to analyse individual technique and team performances
What is video motion analysis ?
- high speed cameras and computer software to analyse frame-by-frame footage
- analysis can take place either immediately after performance or in a more controlled lab setting
What is performance analysis ?
- objective feedback
- for a performer who is trying to get a positive change in performance
- feedback can be given off many indicators
- e.g. successful passes. distance ran, shots taken
What is indirect calorimetry ?
The measurement of the amount of heat generated in an oxidation reaction by determining the consumption of oxygen or the carbon dioxide expired
What is metabolic cart ?
Device which works by attaching head gear to a subject while they breathe a specific amount of oxygen over a period of time
How is metabolic cart used for indirect calorimetry ?
- non-invasive and highly accurate method of metabolic rate
- test indirectly measures how much energy your body uses at rest by measuring the amount of oxygen you consume compared to the amount of carbon dioxide you expire
- information is converted into the heat equivalent rate
- results measured in REE
- results can differ due to the height, weight, gender and age of an athlete
How is an indirect calorimetry test used in sport ?
- to calculate resting energy requirements - minimal nutritional needs
- estimate additional calories needed for activities
- predict calories needed for weight maintenance, loss or gain
- useful for sports events with weight categories
- useful for those following intense exercise programmes to ensure sufficient calories
How is GPS and tracking software used ?
- tracking systems help coaches monitor players during matches
- immediate information (speed, distance, time, hr, pace)
- improves performance by monitoring success rates in technical performance
- can measure g forces (sports such as formula 1, rugby)
- helps with substitutions and replacement (decreases the risk of injury, gage fatigue levels and manage workload during rehab
What 2 sections has motion analysis developed into ?
Notational match analysis = used to record aspects of individual or team performance
Biomechanics = used to analyse the sporting impact of body moments (also known as kinematics)
- They both use quantitive data to make the data accurate, reliable and valid
How can GPS tracking be utilised ?
- tracking devices deliver information in real-time
- distance and intensities can inform coaches of player workload
- Post injury workloads can be managed to ensure athletes aren’t over-exerting
- Inexpensive devices are now available to the amateurs - e.g. sports watches
Why is monitoring data integrity important ?
- to ensure that data is entered into the system and recorded exactly as intended
- this means that the data is the same as when it was originally recorded
How can GPS data integrity can be compromised ?
- human error
- when data is moved from one computer to another
- software bugs and viruses
- hardware malfunctions such as disks crashing
How can the threat of data integrity being compromised be minimised ?
- regularly backing up data
- controlling access to data and protecting against malicious intent
- interfaces which prevents the input of invalid data
- using error detection and correction software when transmitting data
- not leaving a computer unattended
What are the five functions of sport analytics ?
- monitoring fitness for performance
- skill and technique development
- injury prevention
- game analysis
- talent ID
How is monitoring fitness for performance a function of sport analytics ?
- Elite athletes are continually pushing the boundaries of fitness
- Monitoring of fitness can be accessed through sports analytics such as heart rate monitors, smart watches etc
- Data such as heart rate, distance, calories burnt are easily accessible for both recreational and elite performers
- Coaches use data to analyse or for the individual performer to increase motivation
