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 is sports analytics?
Studying data from sports performance to try to improve performance.
What is quantitative data?
Data that can be written down or measure precisely and numerically.
What is qualitative data?
Data that is descriptive and looks at the way people think or feel.
What is an example of quantitative data being used to prove a hypothesis?
. on a numerical scale; could compare the relative effect of different environments on exercisers’ moods: cycle trails in woodland areas vs urban trails.
What is an example of qualitative data?
Interviews with players with sports psychologist determining the feelings and anxiety.
What is objective data?
Fact-based information which is measurable and usable
What is subjective data?
Based on personal opinion, which is less measurable and often less usable.
What is an example of objective data?
The level achieved on the multi stage fitness test
What is an example of subjective data?
When a parent gives their child their opinion on the match so far at half time.
What is validity?
An indication of whether the data collected actually measures what it claims to measures.
What is reliability?
Refers to the degree to which data collection is consistent and stable over time.
Explain quantitative reliability?
Researchers complete the same test on an individual a number of times getting the same/similar results and so methods must be correct.
Explain qualitative reliability?
Researchers placing results/observations/responses into same or similar categories so opinions don’t change.
What is video motion analysis?
A technique used to get information about moving objects from video.
What two types of video motion analysis exist?
. Notational match analysis
. Biomechanics
What is notational match analysis? and give example
Records aspects of individual or team performance
e.g. prozone (completed passes, distance covered, shots on target)
What is biomechanic video analysis? and give example
Analyses the sporting impact of body movements
e.g dartfish
When is video analysis used?
. During performance to quickly fix weaknesses
. After performance to improve
. Before performance to pick out opponent weakness
. During training to iron out weaknesses
What is performance analysis and why is it important?
The provision of objective feedback to performers trying to get a positive change in performance.
Performers can only remember 30% of their performance.
What is a metabolic cart?
A device that works by attaching headgear to a subject while the person breathes a specific amount of oxygen over a period of time.
What is indirect calorimetry?
The measurement of the amount of heat and energy generated in an oxidation reaction.
How is indirect calorimetry measured?
Headgear from the cart is attached while they breathe for a specific amount of time. The gas flows are then converted to a heat equivalent.
What does indirect calorimetry measure?
.Oxygen and c02 concentrations
. Inspiration and expiration volumes
