Sport Technology Flashcards
What is calorimetry
Measurement of energy eliminated or stored in any system
What is indirect calorimetry
Technique where headgear is attached to a subject while they breath for a specific amount of time
What is a metabolic cart in indirect calorimetry for
An electrical medical tool used to measure the body’s metabolism through the amount of heat produced when the body is at rest
Indirect calorimetry - resting energy expenditure
Amount of energy, usually expressed in kcal , required for a 24hr period by the body during rest
Benefits of indirect calorimetry
Help individuals
Determine there energy requirements and response to nutrition
Calculate energy expenditure
Negatives of indirect calorimetry
Sources of error affecting the validity and reliability:
Inaccuracies from air leaks
Difficult to use on children
Overfeeding/ underfeeding may occur based on results
What does a GPS do
Helps coach monitor players
Real time data
Small portable devices
GPS in rugby
Measures impact in G forces
Helps coaches make objective decisions
Football and GPS
Tracking will help them reach their goals
Speed and distance covered can be monitored
GPS- benefits
Improves tactical analysis of a club
Helps coaches compare players
GPS- negatives
Expensive
Unreliable
Quantitive
Use of analytics for fitness
Popular for high and low levels of performance - Apple Watch
Used for elite training
Use of analytics in skill and technique
Use of video analysis can help development of skills
-dartfish
Use of analytics in injury prevention
Whole body vibration
Applied directly to area
Benefits of analytics in injury prevention
Improve bone density
Improve muscle mass
Improve circulation
What is electro stimulation
The production of a muscle contraction using electrical impulses
Benefits of electro stimulation
Increase in strength and power
Improves recovery time by removing lactic acid
How electrostimulation works
Provides a gentle external electrocution of the muscle
Reduces what the brain does
Development of equipment and facilities
Adapted equipment for various people to help remove barriers
New devices are being created to help people
Wheelchairs in sport
Tennis and basketball require light wheelchairs
Contact sports (rugby) require stronger chairs
Modified equipment for elders
Finger extensions exerciser
Exercise balance beam
Low impact pedal exercise machine
Examples of prosthetic devices in sport
Prosthetic legs for running/cycling
Prosthetic arm
Artificial surfaces aim
To increase participation by providing sports facilities for local communities
Pros of artificial surfaces
Similar properties to grass
Consistent conditions
Player on for longer
Cons of artificial surfaces
Too rigid - joint injuries
MUGAS
Made of artificial grass- best solution to providing multi sport opportunities - helps places people play
Pros of development of facilities and equipment
Sports science support- help understand strength and weakness
Medicine- development can help with injury such as vibration
