what are video analysis programmes
coaches, athletes use video, DVD, or digital technology to analyse technique and team performance
what are the functions of video analysis programmes
highlight strengths and weaknesses of performance
analyse gait (technique) and biomechanical aspects of performance
what is video motion analysis
high speed camera and computer software allowing frame by frame playback of footage
what are the functions of video motion analysis
-individual analysis of technique eg; angle of release
notional match analysis:
team and individual study of movement, strategy and tactic
biomechanics
study of body movements, quantitative based- velocity, speed of movement
global positioning systems
a space based navigation system that provides location and time information
what does GPS do
- monitor movement, positioning
- info like distance travelled, speed, forces involved in collisions
-helps a coach with substitutions
sport analytics
refers to studying data from sport performances to try and improve performance
functions of sport analytics
- monitor fitness for performance
- used to develop skill and technique
- help prevent injury (muscle gun)
- enables coaches to analyse games
-used for scouting
quantitative data
written down or measured precisly and numerically eg; stat analysis
qualitatative data
descriptive, subjective, opinion based as it looks at the way people think and feel, eg; coaches opinion when watching a performance
subjective
personal opinion, less measurable, often less usable
validity
indication of whether the data collected measures what it claims
objective
fact based information, measurable
reliable
refers to the degree to witch data collection is consistent and stable overtime.
what is the metabolic cart
A device which works by attaching a headgear to a subject while the person breathes- measure 02 consumed and co2 produced
calorimetry
measurement of the heat and energy eliminated or stored in any systems
what are the functions of metabolic cart for indirect calorimetry
- electronic tool used to measure the body’s metabolism through heat produced when body at rest.
- process called calorimetry to get measurement- how many cals burnt
- tell medic about persons health
- shows your resting metabolic rate, how your metabolism responds to activity
why do we do it (metabolic card for indirect calorimetry)
- measure metabolism
- indications of overall health
- and how these factors effect metabolism:
- age, - size, - drugs, -gender, - smoking
is the calomitry test accurate, what are the faults
- air leaks decrease acuracy
- recording errors that can occur
- difficult to use on children
- only get a snapshot of moment rather than average
- process measures consumption not needs so over or under feeing could occur
data integrity, how can it be comprimised
- human error when data is entered
- software bugs
- hardware crashes or error when transmitting from one machine to another
threats to data integrity can be minimised by:
- backing up important data
- controlling acsess to data via security mechanisms
- not leaving computers unattended or error detection software
-take care when inputting data
what is data integrity
data being reliable and not manipulated in any way
