what is a metabolic cart for indirect calorimetry
a metabolic cart is an electronic medical tool used to measure the bodies metabolism through the amount of heat produced when the body is at rest
the metabolic cart uses a process called calimatory to get its measurement
the result can tell a medic more about a persons overall health condition
uses computer, monitor and breathing tubes mounted to a cart
what is indirect calorimetry
it is a technique where headgear from the cart is attatched to a subject while they breath for a specific amount of time
the subjects inspired and expired gas flows, volumes and concentrations of 02 and C02 are continuously measured
these measurements are the translated into a heat equivalent
positives of indirect calorimetry
non-invasive
relatively accurate
what do the C02 and 02 figures tell you in inidrect calorimetry
resting energy expenditure (REE)
how does indirect calorimetry help individuals
determine energy requirements
calculate energy expenditure - nutritional requirements
possible sources of error in indirect calorimetry
inaccuracy from air leaks
measurment inaccuracies
difficult to use on children
overfeeding or underfeeding due to results
single snapshots are worse than average results
the process initially measures consumption, not needs
identify different ways that GPS data can help to improve a players performance
- make better use of training time to ensure training meets game demands
- improves the tactical analysis undertaken at the club
- helps coach compare players
- helps to get injured players successfully through rehab
- can monitor success rates in technical performance - rugby - measure impact in G forces
- monitor fatigue level
- helps manage workload when recovering form injury
what is GPS
software tracking systems help coaches to monitor players during a match, as well as training
tracks speed, distance, HR, pace, recovery time, acceleration
what is an example of a non elite athlete gps and what is it used for
STRAVA
via smart phones and watches
all athletes across the world can compare results, to achieve their best
can be used to motivate as well as monitor and inform training
what is data integrity
when data is recoreded into a system, it should be the same as when originally recorded
why could data integrity it be comprimised
human error
error in data transmission from one system to another
software bugs/viruses
hardware malfunctions such as disk crash
how can you minimise risk of comprimising data integrity
regularly back up
controlling access to data and protecting from malicious intent
security mechanisms
take care when entering data
using error detection and correction software
not leaving a computer unattended
