Q

Why should you asses CRF?

A
  • considered one of the best indicators of collective health
  • individualization of exercise prescription
  • tracking and motivating toward exercise progression
  • clinical purposes
  • Low CRF is an independent risk factors for CV mortality

Q

What are two alternative approaches to assessing CRF when VO2 is not feasible?

A

Field tests
- non-laboratory settings
- can be administered to groups or individuals

Q

General procedures for submaximal testing of CRF:

A
  • obtain resting HR and BP immediately prior to exercise in exercise posture
  • familiarization with equipment
  • 2-3 minute warm up
  • a specific protocol should have 2-3 minute stages with appropriate increments in work rate
  • HR should be monitored atleast 2 times during each stage towards the end (if greater than 110 HRss should be reached before moving on)
  • BP should be monitored in the last minute of each stage and repeated if hypotensive or hypertensive response
  • Rating of perceived exertion (RPE) and additional rating scales should be monitored towards the end
  • appearance and symptoms should be monitored regularly
  • test should be terminated when participant reaches 70% HRR
  • appropriate cool down should be initiated
