Technology Flashcards
What is qualitative data?
Data that are descriptive, subjective, feelings and opinions
What is quantitative data?
Objective, numerical, measured precisely
What is validity?
If the data measures what its set out to measure
What is reliability?
Degree that data collection is consistent and can be repeated
What is a metabolic cart? What process?
A device by attaching specialised headgear and is used to measure the persons metabolism through heat.
Calorimetry - Measurement of heat and energy
What is indirect calorimetry?
Where the headgear is attached and measuring the volume of O2 and CO2 inspired and expired
What can indirect calorimetry be used to help?
Determine energy requirements
Calculate energy expenditure - determine nutrition
Difficulties of indirect calorimetry?
Inaccuracies from leaks
Hard to use on children
Inaccuracies from human error
What is data integrity?
Maintaining and ensuring the accuracy of stored data over its lifetime
How can data integrity be compromised?
Human error when inputting data
Software bugs and viruses
Ways to minimise threats to data integrity?
Regularly backing up data
Use error detection
Careful when inputting data
Not leaving computer unattended
What is vibration therapy, what can it be used for?
Can be applied directly onto an affected area of the body or to the whole body
Exercise recovery, injury prevention, rehab
Benefits of vibration therapy?
Improve circulation
Reduced joint pain
Increase muscle power
What is electro stimulation?
Production of muscle contractions using electrical impulses
How can electrostimulation be used to help recovery?
Strength and tone the muscles
Get rid of lactic acid after training
Prevent losses in fitness levels in that muscle
How is fitness monitored for performance?
What does it do?
Using smart watches and sporting devices - provides feedback on aspects of performance straight away
What does MUGAS stand for?
Multi use game areas
Negatives of using technology
Expensive
Can be misleading
Cause a placebo effect
Positive impact of tech on performer
Improve recovery
Improved clothing and footwear
Improved equipment
What are the negatives impacts of technology in sport?
Injury/over aggression
Cheating - taking drugs (hide it)
Expensive and unaffordable
What are the positive impacts of technology on coaches?
Using the information to help tactics
Focus training around the previous game
Identify strengths and weaknesses
What are the negatives to technology on coaches?
Over emphasises on performance analysis data
Using computers, can be hacked
Positives of technology on spectators?
Many websites to follow the sport
Increased excitement
Less frustration
Negatives of technology on spectators?
Breaks in play can be disruptive
Costs of technology pushed onto spectators
