Q

What does video motion analysis involve?

A
  • 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

Q

Why is performance analysis so important?

A
  • 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.

Q

Give an overview of an indirect calorimetry?

A
  • 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

Q

Give an overview of the metabolic cart.

A
  • 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

Q

What two factors does metabolic cart use to calculate heat production?

A
  • 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)

14
Q

What conditions can the REE change depending on?

A
  • 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

Q

How can indirect calorimetry & use of metabolic cart help individuals?

A
  • To determine their energy requirements & response to nutrition over time
  • To calculate energy expenditure which allows determination of nutritional requirements/caloric needs
  • Help individuals who are classified/potentially classified as obese
  • In the calculation of their REE which helps medical staff determine the amount of food & nutrition needed
17
Q

What are some difficulties or sources of error affecting the validity & reliability of using indirect calorimetry via a metabolic cart.

A
  • Inaccuracies from air leaks
  • Possible inaccuracis from measurement recording errors
  • Difficult to use on children
  • Overfeeding/underfeeding may occur based on results recieved
  • Process actually measures consumption, not needs
18
Q

What is GPS software?

A

Global positioning system- Useful in helping coaches monitor players during matches as well as in training

Systems track the speed,distance & direction of indiviudal being monitored

19
Q

How is GPS software useful?

A

Very useful for coaches to monitor players:
* Vast amount of information immediately
* Track speed
* Track distance
* Direction of individual

20
Q

What are the positives of using GPS & motion tracking software & hardware?

A
  • Better use of training time- Training can meet demands of the game
  • Improves tactic analysis- Spacing on the football pitch
  • You can compare player performance
  • Helps to rehabilitate players- i.e dont do too much too soon/faster return to team
21
Q

What else can GPS software help with in sport?

A

Can provide data to improve performance by success rate

Can help coaches to make objective decisions for replacements/substitutes

Can reduce injury as can gauge the fatigue level

22
Q

What is data integrity?

A

Overall intent is to ensure data is entered into the system & recorded exactly as intended & when retrieved later to ensure the data is the same as when it was originally recorded

23
Q

How can data integrity be compromised?

A

Through:
Human error when data is entered
Errors occuring when data is transmitted from one computer to another
Software bugs/viruses

24
Q

What ways are there of minimising threats to data integrity?

A
  • Regularly backing-up data
  • Controlling access to data & protecting it against malicious intent via security mechanisms
  • Using error detection & correction software when transmitting data
  • Not leaving a computer unattended for anyone to access.
