Question 11

Video motion analysis

Answer 11

A technique used to get information about moving objects from video

Question 12

What are the two types of Video motion analysis

Answer 12

• Notational match analysis
• Biomechanics

Question 13

Notational match analysis

Answer 13

Used to record aspects of individual/team performance, such as movement patterns, strategy and tactics. Obtains objective qualitative data

Question 14

What are two types of notational match analysis

Answer 14

• Dartfish
• Prozone

Question 15

Biomechanics

Answer 15

• Used to analyse the sporting impact of body movements
• Quantitative based study
• Kinematics
• Sensors on their joints and often muscles of the body
• Filmed performing skill often in a lab
• Injury prevention

Question 16

Performance analysis

Answer 16

The provision of objective feedback to performs trying to get a positive change in performance

Question 17

Indirect calorimetry

Answer 17

The measurement of the amount of heat and energy generated in an oxidation reaction

Question 18

Calorimetry

Answer 18

The measurement of the heat and energy eliminated or stored in any system

Question 19

Metabolic cart

Answer 19

A device which works by attaching headgear to a subject while the person breathes a specific amount of oxygen over a period of time

Question 20

Resting Energy Expenditure (REE)

Answer 20

The amount of energy, usually expressed in Kcal, required for a 24 hour period by the body during rest

Question 21

What can Indirect calorimetry and use of a metabolic cart can help individuals to do

Answer 21

• Determine energy requirements and response to nutrition
• To calculate energy expenditure
• Who are classified as obese
• Calculation of REE

Question 22

What are the potential difficulties affecting validity and reliability using indirect calorimetry via a metabolic cart

Answer 22

• Inaccuracies from air leaks
• Possible inaccuracies from measurements
• Difficult to use on children
• Overfeeding or underfeeding may occur
• Singe snapshots are worse than average results over a longer period of time
• The process actually measures consumption, not needs

Question 23

Computer software

Answer 23

Computer software is any set of machine-readable instructions which direct a computer’s processor to perform specific operations

Question 24

Computer hardware

Answer 24

Computer hardware is the physical components of computers

Question 25

'G' forces

Answer 25

Forces acting on the body as a result of acceleration or gravity e.g. G-load/force of an American football 'hit' on an opponent

Question 26

What does GPS stand for

Answer 26

Global Positioning System

GPS

Answer 27

A space based navigation system that provides location and time information

Question 28

Benefits of GPS technology for player tracking

Data integrity

Answer 29

Maintaining and ensuring the accuracy and consistency of stored data over its entire lifetime

Question 30

How can data integrity be compromised

Question 31

Ways to minimise threats to data integrity

Question 32

Smart device

Answer 32

Worn or attached to performers body while in use to provide instant feedback on aspects of performance such as distance covered, HR etc

Question 33

Two ways analytics can help in injury prevention

Answer 33

- Vibration technology - Electrostimulation

Question 34

Vibration technology

Answer 34

Vibration training/therapy is also known as whole body vibration and a example of its usage involves the use of vibration plates to induce exercise effects in the body

Question 35

Electrostimulation

Question 40

Compression garments

Answer 40

Items such as elasticated leggings, socks, shirts worn to promote recovery by improving circulation

Question 41

Positives of technology in sport

Answer 41

+ Improved detection of doping with modernised testing devices + More accurate decision making allowing for fairer results + Better timing devices and increased recording of performance + Improved detection of foul play e.g. VAR/TMO + Improved quality of performance

Question 42

Negatives of technology in sport

Answer 42

- Access to modern technology can be limited - More accessible to sports which are more financially secure - Increased pressure on officials to make correct decision - Performance Enhancing Drugs testing cannot keep up with new drugs developed
