Question

1.) The Biodex Balance System may be used to test or train balance.

True or False

2.) In general, health and fitness benefits increase as individuals increase either the amount or intensity of physical activity.  

True or False

3.) Because spirometry testing is effort dependent, a test administrator who can motivate the patient/client is essential to obtain valid and reliable results.  

True or False

4.) The variability between BIA analyzers is small so different analyzers may be used when tracking a client's body composition changes over time.  

True or False

Answer 1

1. True

Explanation: Biodex Balance System is a simple efficient tool which can be used for balance screening and balance training .
It helps to improve balance, develop muscle tone, increase agility, and treat many pathologies.

2. True

Explanation: when individual increases either the amount or intensity of physical activity, health and fitness benefits increases .
It helps to reduce weight, prevents obesity and thus protects from the risk of cardiovascular diseases, hypertension,prevents other diseases and illness, boosts energy,improves the mood, and promotes better sleep.

3. true

Explanation: Spirometry is used to monitor the lung condition periodically and to assess whether treatment for a lung disease helps to breathe better.

This is an effort dependent instrument. To do the test we have to sit and breath into a spirometer.
For it to be effective someone has to give instructions about how to use this machine properly. Then only we will get valid and reliable results.
4. False

Explanation: Every BIA analyze instrument have different types of small erorrs,the 2 main errors are accidental error and systemic error.
So using different BIA Analyzer for analzing the same person can increase the total error.Hence it is better to use a single BIA analyzer for a person to reduce the error.
