Summary Aerobic Exercise Intensity assessment and prescription

A snapshot of the summary - Aerobic Exercise Intensity assessment and prescription

• 1 Introduction

• Which 4 modalities need to be specified to make an exercise regime tailormade?

  • Intensity
  • Mode
  • Duration
  • Frequency
• What was the aim of the joint statement?

  provide professional with a reappraisal of all aspects related to aerobic exercise intensity assessment and prescription. Including cardiac patient groups.
• Which 4 Key issues will be discussed in this joint statement?

  1. identification of different exercise domains based on the physiological response (HR, HRR, VO2, RPE) to constant-work-rate (CWR)
  2. methods that directly and/or indirectly determine exercise intensity in both continuous and interval aerobic training
  3. effects of different exercise protocols on intensity
  4. recommendations for exercise training prescription in some cardiac patient groups
• What is the recommended weekly frequency to exercise?

  3-4 times a week for moderate exercise intensity when taking into account exercise duration.
• How is 'continuous' exercise defined?

  As 20mins with a mild to moderate sense of fatigue.

• 2 Direct Exercise Intensity Assessment: physiological bases

• 2.1 Descriptors of the O2 Transport and Utilization System Response

• Which quantitive measures are usually used to directly asses exercise intensity?

  • VO2
  • Lactate

• 2.1.2 Second Ventilatory Threshold

• How is the Second Ventilatory Threshold defined?

  • VE/VCO2 crosses VE/VO2
• What makes the 2nd Ventilatory Threshold difficult to define?

  The relative sensitivity of the chemoreceptors to acidosis.
• Which quantitative values of VO2 and HR correspond to the 2nd Ventilatory Threshold?

  • 70-80% peak VO2
  • 80-90% peak HR

• 2.1.3 Peak VO2

• How is peak VO2 defined?

  • Plateau of the VO2 and HR
  • RER > 1.1
  • RPE > 18
  • Lactate > 8mmol/L
