Step1: Perform a measure of CRF

• • Measures of CRF eg:
  • Chester step test
  • 6 minutes walk test
  • shuttle walk test
  • need to be able to convert walking speed for cardiac population into METs
  • e.g. walking speed of 65 metres per min from 6 minute walk test = 4.3 METs

  
• Estimating METmax:

  • estimating from a submaximal test what someone would likely score in a maximal test
  • e.g. 4.3 METs at 60% HRR = 7.5 METs at 100% HRR
