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
    • patient appearing exhausted
