Q

What is qualitative data?

A

Data which is descriptive and looks at the way people think or feel; it is sometimes less precise and potentially less meaningful than quantitative data. It can also be very time consuming to collect and analyse such data.

Q

What are examples of gathering quantitative data in sport in order to try to prove a hypothesis being tested?

A

In sports psychology, the potential positive link between motivational self-talk and its relationship to improving self-paced skills (e.g. a golf putt).

In exercise psychology, research of quantitative nature (e.g. on a numerical scale) could compare the relative effect of different environments on exercisers’ moods (e.g. cycle trails in wooded areas versus cycling lanes in urban areas).

Q

When is qualitative data used in sports?

A

In sports psychology, qualitative methodology such as open ended questions with focus groups can be used to explore the feelings of anxiety among athletes prior to performance at major sporting competitions.

In exercise psychology, in-depth interviews could be used to help establish whether more frequent exercisers have a more accurate understanding of their injuries than less frequent exercisers.

Q

Q

What is an example of reliability in quantitative research?

A

Can be when one researcher conducting the same test (e.g. skinfold measurements) on the same individual on a number of occasions and getting the same of very similar results. Alternatively, it can be different researchers conducting the same test on the same individual and getting the same or very similar results.

Q

What is an example of reliability in qualitative research?

Q

How can reliability be affected?

A

By errors that occur when researchers do not know how to use equipment correctly, e.g. the use of skin-fold calipers when assessing body composition. Also by poorly maintained equipment which may give incorrect readings.

Q

If the data is not valid, what is the reliability likely to be like?

Q

Why are digital technology used in sport more frequently by coaches and athletes?

A

To analyse individual technique as well as team performances.

At individual level - video analysis can also be used to analyse gait and biomechanical aspects of performance, with any information gained also potentially able to help in injury rehabilitation.

18
Q

What is video motion analysis?

A

A technique used to get information about moving objects from video.

19
Q

What does video motion analysis usually involve?

A

A high-speed camera and a computer with software allowing frame-by-frame playback of the footage on video.

20
Q

Why/when is video motion analysis useful?

A

Useful in the individual analysis of technical performance (e.g. to identify and correct problems with an athlete’s technique such as the angle of release when throwing a shot etc).

21
Q

What can video motion analysis take place?

A

Either immediately after performance (e.g. at the side of the track) or it can be undertaken in a more controlled laboratory environment.

22
Q

What 2 distinct sport science disciplines has the process of motion analysis developed into?

A

Notational match analysis - used to record aspects of individual or team performance.

Biomechanics - used to analyse the sporting impact of body movements (this is sometimes called kinematics).

23
Q

What 2 things do notational match analysis and biomechanics have in common?

A

The use of measured observation (quantitative analysis) during or after an event to quantify performance in an accurate, reliable and valid way.

They both rely on IT for data analysis.

24
Q

What is performance analysis (PA)?

A

The provision of objective feedback to a performer who is trying to get a positive change in performance.

(Feedback can be gained on a variety of performance indicators including: the number of passes made; pass completion success rates; distance run in kilometres; number of shots attempted; number of shots on target, etc.)

25
Q

Within a training environment, why is immediate visual feedback software useful?

A

To provide images pre- and post-training feedback for the athlete and coach to compare.

26
Q

What problems could there be if performance analysis isn’t used by athletes and coaches?

A

Poor immediate decisions being made as well as longer term in relation to an athlete’s training programme.

27
Q

What is indirect calorimetry?

A

The measurement of the amount of heat/energy generated in an oxidation reaction by determining the intake or consumption of oxygen or by measuring the amount of CO2 released and translating these quantities into a heat equivalent.

28
Q

What is a metabolic cart?

A

A device which works by attaching headgear to a subject while they breather a specific amount of oxygen over a period of time.

29
Q

What is calorimetry?

A

Measurement of the heat/energy eliminated or stored in any system.

30
Q

What equipment is used when measuring indirect calorimetry?

A

A metabolic cart.

31
Q

What factors can affect REE (resting energy expenditure)?

A

Overall weight or height to weight ratio, age and gender, and the body’s response to certain drugs.

32
Q

In which gender is REE lower?

A

Females.

33
Q

What is resting energy expenditure (REE)?

A

The amount of energy, usually expressed in Kcal, required for a 24-hour period by the body during rest.

34
Q

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

A
  • To determine their energy requirements and response to nutrition over time.
  • To calculate energy expenditure which allows determination of nutritional requirements/caloric needs.
  • Who are classified/potentially classified as obese.
  • In the calculation of their REE, which helps medical staff determine the amount of food and nutrition needed.
35
Q

What are the possible difficulties or sources of error affecting the validity and reliability of using indirect calorimetry via a metabolic cart?

A
  • Inaccuracies from air leaks.
  • Possible inaccuracies from measurement/recording errors.
  • Difficult to use on children.
  • Overfeeding/underfeeding may occur based on results received.
  • Single snap shots are worse than ‘average results/studies’ over a longer period of time.
  • The process actually measures consumption not needs.
36
Q

What is software and hardware?

A

Computer software is any set of machine-readable instructions which direct a computer’s processor to perform specific operations.

Computer hardware is the physical component of computers.

37
Q

Define GPS (Global Positioning System):

A

A space-based navigation system that provides location and time information.

38
Q

Why are GPS systems useful?

A

Help coaches and player in training and matches as they track speed, distance and direction of individuals. Also can measure HR, pace, recovery times and the amount of dynamic acceleration etc.

Cna also provide data to improve performance via monitoring success rates in technical performance.

It can measure the ‘G’ force in contact sports like rugby.

Help make objective decisions about possible replacements and substitutions which can help decrease the risk of injury as it can gauge a players fatigue level.

When players are coming back after injury, it can help to manage the workload during their rehabilitation..

39
Q

What are reasons for using GPS technology for player performance and work tracking?

A

Makes better use of training time/ensures training meets game demands.

Improves the tactical analysis undertaken at a club.

Helps a coach compare player performance and potentially ‘pick the best players’ for the team based on GPS data.

Helps to get injured players successfully through rehab at a faster rate.

40
Q

What is data integrity?

A

Maintaining and ensuring the accuracy and consistency of stored data over its entire lifetime.

41
Q

What is data integrity using sports analytics?

A

Refers to the validity of data (i.e. its relevance/meaningfulness).

42
Q

In what ways can data integrity be compromised through?

A
  • Human error when data is entered.
  • Errors occurring when data is transmitted from one computer to another.
  • Software bugs of viruses.
  • Hardware malfunction such as disk crashes.
43
Q

What are ways to minimise threats to data integrity?

A
  • Regularly backing-up data.
  • Controlling access to data and protecting against malicious intent via security mechanisms.
  • Designing interfaces which prevent the input of invalid data; taking care when entering data.
  • Using error detection and correction software when transmitting data.
  • Not leaving a computer unattended for anyone to access.
