The Role of Technology on Sport 7.0 Flashcards
What is sports analytics?
- Collections of relevant historical statistics that can provide a competitive advantage to a team or individual
What is qualitative & quantitative data?
Qualitative- subjective data as it looks at feelings,opinions & emotions
Quantitative- Objective, factual information & numerical based
What is objective & subjective data?
Objective- Information recieved based on facts
Subjective- Information based on personal opinions, assumptions, interpretations etc.
Define reliability.
Refers to the degree to which data collection is consistent & stable over time
What is video motion analysis?
- A technique used to get information about moving objects from a video
What does video motion analysis involve?
- Involves a high speed camera to produce frame by frame playback
- Useful to analyse technical performance e.g. Putting in golf, release when throwing a shot put,
Can take place either immeidately after performance (e.g. at side of track) or in a more controlled laboratory environment
What two distinct sport science disciplines 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 movements
What is performance analysis?
The provision of objective feedback to a performer who is trying to get a positive change in performance
Why is performance analysis so important?
- Extremely important to enahnce performer
- Without it- at a loss against others in competitions
- Variety of PA techniques used to provide; task, performance and physiological data.
Give an overview of an indirect calorimetry?
- Headgear is attached to a subject
- Breathe for a specific amount of time
- Their inspired and expired gas flows, volumes and concentration of O2 and CO2 are all measured
- Continuous measurement of oxygen O2 consumption and production of CO2
- Non-invasive technique & relatively successful
- The equipment used is known as a metabolic cart
Give an overview of the metabolic cart.
- Electronic medical tool used to measure the body’s metabolism through the heat produced when the body is at rest
- The result can help to inform doctors of a persons overall health
- Parts of device – computer system, monitor, breathing tubes on a mobile push cart
- 2 factors to calculate heat production
- Measurement is resting energy expenditure (REE) – results can change
What is the equipment used when measuring indirect calorimetry?
A metabolic cart- A device used to measure the body’s metabolism through the amount of heat produced when the body is at rest
What two factors does metabolic cart use to calculate heat production?
- Intake of oxygen from the body
- Output of carbon dioxide
These two figures will provide the result for metabolic cart which is measure as resting energy expenditure (REE)
What conditions can the REE change depending on?
- Weight or height to weight ratio
- Age
- Gender
- The body’s response to various drugs
Due to differences in size it is lower in women than in men
Define resting energy expenditure (REE).
The amount of energy, usually expressed in Kcal, required for a 24 hour period by the body during rest
