Technology in sport Flashcards
What is sports analytics?
Studying data from sports performances to try and improve performance
What is quantitative data?
Objective information that is numerical
What is qualitative data?
Subjective info that is worded, focus on thoughts and feelings
What is validity?
The degree in which the data measures what it claims to measure
What is reliability?
When the data is consistent when data collection is repeated at a later date
What are the 2 types of video motion analysis?
Notational match analysis
Biomechanics
What is biomechanics?
The analysis of the sporting impact of body movements
What is notational match analysis?
The study of movement patterns, strategy and tactics of a performer/team
What do notational match analysis and biomechanics have in common?
Both use measured observation (quantitative) in order to quantify performance in an accurate and valid way/
What are the benefits of video analysis?
Help formulate strategies against opponents by looking at stats
How can reliability be affected in research?
Human error from incorrect equipment use
Poor accuracy from faulty equipment
What percent of a game can athletes and coaches recall without video analysis?
30%
What are the benefits of performance analysis analysis?
Recognise poor decision making
Can be used to develop an athletes training programme
Can be used to formulate tactics and strategies by viewing stats of other team/athletes
Identify strengths and weakness
What is indirect calorimetry?
Measurement of amount of heat and energy generated in an oxidation reaction expressed as REE
What is resting energy expenditure REE?
Amount of energy in Kcal required for a 24 hour period by the body at rest
What affects the REE of a performer?
Weight
Height
Age
Gender
Lifestyle/habits
What is a metabolic cart?
An electronic medical tool used to measure the bodies metabolism
Benefits of indirect calorimetry and use of metabolic cart
Determine athletes response to nutrition
Classify obesity
Determine athletes nutritional needs
What are the components of the metabolic cart?
Computer system
Breathing tubes
Mobile push cart
What are the sources of error and difficulties when using the metabolic cart?
Consumption, not needs
Leakage of air
Overfeeding or underfeeding
Single snapshots not as effective as average results overtime
Errors in measurement may occur
CLOSE
What are G forces
Forces acting on body as a result of acceleration or gravity
What is GPS
Global positioning system
What can GPS measure?
Heart rate
Pace
recovery time
Acceleration
Benefits of using GPS tech
Better use of training by ensuring it mimics game demands
Improve tactical analysis
Compare player performance and pick players with the best stats
Help injured players recover faster by managing workload
What is data integrity?
Ensuring data is recorded into a system exactly as intended and can be retrieved the same as it was entered
What ways can data integrity be comprimised?
Human error when data enetered
Errors when transferring data between computers
Malware
Hardware malfunction
What ways can threats to data integrity be minimised?
Regularly backing up data
Security mechanism to protect from malware
Take care when inputting data
Use error detection and correction software
Not leaving computer unattended
What is an example of analytics software?
Dart fish
What are the benefits of using electrostimulation technology?
Strengthen and tones muscle to prevent injury
Prevent fitness losses during periods of inactivity
Assist rehabilitation by strengthening injured or weak areas
Help remove lactic acid
Drawbacks of electrostimulation tech?
Overuse makes it ineffective
Stimulation for too long will exhaust muscles
In what 4 ways can sports analytics be used?
Monitor fitness
Skill and technique development
Game analysis
Talent ID
How has technology aided in disbaled sport?
Adapted lightweight wheelchairs for fast paced sports
Prosthetics developed for running to be lightweight and powerful strides
Low impact pedal exercise allows elderly to exercise without great strain on joints and stimulate circulation
What is the “Places people play” initiative?
Initiative by sport england to provide facilities for sport
Benefits of technology on sport
Increase participation by increasing inclusivity
Increase facility quality
Aid development player and overall quality
Drawbacks of technology on sport
Data may be misleading
Cna be expensive, causing inequalities
Become too reliant on data, decreases creativity
May have placebo effect
Benefits of technology on performers
Improved clothing or footwear
Imrpoved sports and protective equipment
Improved recovery time
Imrpoved rehabillitation time
Increased nutrional and supplement knowledge
Performance feedback
Drawbacks of technology on the performer
Lead to injury or over aggression if performer feels “invincible”
Drugs can become undetected, causing cheating
Expensive
Benefits of tech on coach
Can be highly informative
Can aid in creation of training programmes
Negatives of tech on coach
Hindernace if over reliance on tech
Potential hacking can cause tactics and strategies to be exploited
Benefits of tech on audience
Reduce frustration from correct decisions
Helps officials communicate and audience can sometimes hear
Audience can easily view stats at games
Increased excitement awaiting decisions
Drawbacks of tech on audience
Loss of respect to official
Some venues may not afford the tech
Breaks in play can be disruptive, official overuses
Tech not welcomed by all
