Q

GPS common outcome measures are (3)?

A

1) Work rate (e.g. meters/min etc)
2) Load and accumulated mechanical stress (e.g. metabolic power)
3) Position specific data or player characteristics

17
Q

The reliability and validity of GPS depends on…

A
  1. Number of satellites connected
  2. Changing units and vest size
  3. Higher speed (Hz level)
  4. Validity of load markers
  5. Environment (cloud cover)
18
Q

Factors to consider with GPS application in the real world? (3)

A
  1. Decide which variables are relevant for your needs
  2. How relevant are these variable to the success of the team
  3. Are these for injury prevention (overload) or sport performance.
19
Q

Power meters measure

A

speed, power, acceleration, cadence, etc

20
Q

The equation to determine load is…

A

Load = no. of sets x no. of reps x weight lifted

21
Q

____ ____ is the training process that requires effectively planned, monitored and manipulated load to promote adaptation and improve fitness whilst minimising fatigue

A

external load

22
Q

What athletes ‘do’ is classed as…

A

external load

23
Q

The second method of calculating volume load =

A

load = sets x reps x %1RM (RPE)

24
Q

Optical-based tracking system (using 2 cameras) benefits include…

A
  • non invasive (dont wear anything)
  • commonly used in football/soccer
  • High sampling rate (can even track ball)
25
Q

Optical-based tracking system (using 2 cameras) limitations include…

A
  • limited number of measurements
  • tracking occlusions require manual corrections
  • installation time
  • expensive
  • permanent camera set up
  • 2D plane movements measure (no jumps)
  • error rates increase with velocity
26
Q

Local positioning system vs GPS

A

local positioning system does not have to go up into satellite like GPS does (hence ‘local’)

27
Q

Benefits of local positioning system…

A
  • High number of measurements possible
  • Accuracy of measured data in real time
  • ultra wide band technology reduces chances of interference and transmission path
28
Q

Limitations of local positioning system…

A
  • fixed installation
  • expensive
  • installation time
  • error rates increase with velocity
  • permanent set up
29
Q

GPS/GNSS satellite system benefits…

A
  • High number of measurements possible
  • short installation time
  • Operator not needed
30
Q

GPS/GNSS satellite system limitations…

A
  • device attached to player and device size
  • satellite signal line of sight in stadium
  • Accuracy concerns of measured data
  • error increases with velocity
  • units not interchangeable
  • cant track ball
  • cloud cover / location and interference (roof/wall)
  • > 10Hz likely required for professionals
  • need software
31
Q

The basic elements the GPS measures include… (4)?

A
  • Distance (how far?)
  • Duration (how long?)
  • Velocity (how fast, how many times, average speed)
  • Acceleration (how many)
32
Q

How do you calculate the Z score?

A

Z score = current score - average score / SD
