Q

quantitative

A

numerical data
data written/measure precisely
e.g. VO2 max test heart rate monitor, stat analysis from matches, surveys, questionnaires

ADV: extremely factual, formal objective data, easy to compare
DIS: not much detail/depth of whole performance

Q

qualitative

A

descriptive data and looks at way people think or feel
e.g. interviews/observations

ADV: gain clear understanding of athlete experience, contain lots of details
DIS: open to interpretation/opinion (subjective), time consuming when analysing data, less meaningful

Q

subjective

A

open to interpretation
based on personal opinion less measurable
e.g. works harder in training
e.g. doesnt tire easily

Q

monitor fitness for performance

A 
calories burned/calories input 
steps/distance 
resting & working HR 
pace 
sleep
  • know effort & fitness levels & threshold
  • help setting goals & tailor training programme

Q

develop skills and technique

A 
e.g. Dartfish 
injury prevention 
improve performance strategies 
highlight mistakes 
analyse opponents

provide tactical, technical, statistical data which is used to improve team’s performance

12
Q

vibration technology

A

used in injury prevention, recovery, rehabilitation (applied straight to affected area = direct) (transferred to whole body = indirect)

pros: 
reduce muscle stiffness/DOMS 
boost metabolism 
increase muscle mass 
increase blood flow 
reduce pain

Q

electrotherapy

A

small electrical impulses to repair tissue, stimulate muscles and increase sensations and muscle strength (send small electrocution to muscles= stimulate)

pros:
increase strength/power of muscles e.g. ankle stability
reduce recovery time = expelling lactic acid out of muscles
promote blood flow
prevent loss in fitness levels while inactive (used to stimulate muscles = maintain time, help with recovery athletes coming back from)

Q

scout talent/talent ID

A

computer vision machine learning and other forms of AI = algorithms
game videos/data from sensors = identify talent
e.g. baseball (stats = evaluate players, throwing speed/spin, video tracking players moving round field/swing speed/mechanics from sensor = studded bats)

e.g. basketball (Computer vision systems = track ball/players move around = how teammates move

Q

analyse games/performance

A

coaches/athletes use video analysis programmes = assess technique/team/ individual performance = programmes tend to collect quantitative data

16
Q

video motion analysis

A

used to study movement patterns, strategy, technical play in teams performance (see in action)
biomechanics of action = gather info

qualitative or quantitative

17
Q

benefits of video motion analysis

A
  1. provide feedback during/after game
  2. helps with injury prevention (identify incorrect technique)
  3. better communication with coaches and players
  4. increase performance levels
18
Q

GPS & motion tracking software

A

measure speed, distance, HR, pace, recovery time

e.g Strava

19
Q

benefits of GPS/motion tracking

A
  1. high impact sport = measure G forces on player = substitution ?
  2. data provided immediately
  3. aid recovery = monitor workload during rehabilitation
  4. know what fitness zone in = coach analyse = SMARTER goals = improve performance
20
Q

positive role of technology for a coach in analysis of team games

A
  1. identity talent
  2. injury prevention
  3. coach plan ahead based on previous
  4. create tactics
  5. visually identify strength/weakness = change
21
Q

negative role of technology for a coach in analysis of team games

A
  1. data not be shown immediately after error
  2. over reliant (break focus on stats more)
  3. expensive, unaccessible to all levels
  4. doesnt show full picture
  5. not reflect true ability/performance
  6. potential hacking/compromise data
22
Q

calorimetry involves

A

metabolic cart = equipment

23
Q

stages of the metabolic cart

A
  1. headgear tubes attach to cart
  2. breath for specific time period
  3. vol of O2 and CO2 in/out measured
  4. = amount of heat released = generate measurement = REE
24
Q

resting energy expenditure

A

REE kcal

amount of energy required for a 24 hr period by body during rest

25
Q

REE results vary due to

A
  1. drugs
  2. smoking
  3. age
  4. sleep
  5. height to weight ratio
  6. gender
26
Q

benefits of using metabolic cart for individual

A
  1. determine energy expenditure/ response to nutrition over time
  2. calculate calorific needs
  3. classified as obese?
  4. how much food/nutrition to consume
27
Q

difficulties that may affect validity and reliability when using metabolic cart to measure calorimetry

A
  1. difficult to use on children
  2. inaccuracies from air leaks
  3. carried out over period of time (results vary during day)
  4. inaccurate result in over/under feeding
  5. human error reading measurements
  6. genetic factors
28
Q

data integrity

A

maintaining and ensuring accuracy and consistency of stored data over entire lifetime

29
Q

integrity

A

quality of being honest and strong moral principles

30
Q

issues when storing data

A
  1. software bugs/viruses
  2. hardware fault/crashing disk
  3. human error entering data
  4. error when moving from 1 computer to another
31
Q

preventing issues when storing data

A
  1. error detection/correction software when transmitting data
  2. dont leave computer unattended
  3. protect with security mechanism
  4. regularly back up existing data
