Technology Prt.2

Question 1

List the Two Types of Testing and Recording Equipment.

Answer 1

Metabolic Cart.
Calorimetry.

Question 2

Define Metabolic Cart.

Answer 2

A device that works by attaching headgear to a subject while the person breathes.

Question 3

Define Calorimetry.

Answer 3

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

Question 4

List the Functions of the Metabolic Cart for Indirect Calorimetry.

Answer 4

An electronic tool used to measure the body’s metabolism through heat produced when the body is at rest.
Uses a process called calorimetry to get measurements.
Tell medics more about a person’s health.

Question 5

Define Indirect Calorimetry.

Answer 5

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

Question 6

Define REE.

Answer 6

Resting Energy Expenditure.
The amount of energy usually expressed in kcal, required for 24 hours by the body during rest.

Question 7

List the Functions of Indirect Calorimetry.

Answer 7

Indirect uses volumes of gases breathed in and out to measure heat/energy use, this determines REE.
It calculates the measurement of O2 uptake and CO2 production.
It can also be used to measure VO2 max.

Question 8

List the 4 parts of the Metabolic Cart.

Answer 8

1. Computer with the data collecting program.
2. Monitor to display readings.
3. Breathing tubes and mask.
4. Sometimes comes with a harness.

Question 9

Define Calorimetry.

Answer 9

The measurement of the heat and energy eliminated or stored in a system.
Measuring the amount of energy burned or stored in the body.

Question 10

Explain the Metabolic Cart Method.

Answer 10

Indirect calorimetry is performed using a metabolic cart by placing the headgear, which has the breathing tubes attached to it.
The breathing tubes capture all the inspired and expired gas.
All the oxygen and carbon dioxide are continually measured and analyzed then converted into a heat equivalent.

Question 11

List the characteristics REE is based upon.

Answer 11

Age.
Drugs.
Weight.
Biological Sex.
Height to Weight Ratio.

Question 12

How is the Metabolic Cart Useful?

Answer 12

How much food do we need to eat in order to give us enough energy to recover and repair.
How much energy is burnt during rest, exercise, and recovery.
Classification of unhealthy people, both obese and malnourished.

Question 13

List the Issues with Reliability and Validity when using the Metabolic Cart.

Answer 13

Children - difficult to use on them, leads to inaccurate results.
Leaks in the breathing masks and tubes.
Overfeeding might occur due to inaccurate results.
Errors can occur easily when taking measurements.

Question 14

Define Data Integrity.

Answer 14

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

Question 15

List the ways Data Integrity can be compromised.

Answer 15

Human error when entering data.
Software bugs and viruses.
Hardware fault/Disk crashing.
Errors occur when transmitting from one computer to another.

Question 16

List the Minimising Threats.

Answer 16

Regularly back up the existing data.
Protect with security mechanisms - controlling access.
Limit input of invalid data - take care when entering data or use error detection/correction software for transmitting data.

Question 17

Explain the Impact of Technology on Equipment/Materials.

Answer 17

Limitations due to age/disability no longer need to create a barrier to participation.
Assistive and adapted technology is an area that is on a constant increase.

Question 18

Explain the Impact of Technology on Facilities.

Answer 18

Technological developments have meant that surfaces are now suitable for multisport provision.
