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?
- identification of different exercise domains based on the physiological response (HR, HRR, VO2, RPE) to constant-work-rate (CWR)
- methods that directly and/or indirectly determine exercise intensity in both continuous and interval aerobic training
- effects of different exercise protocols on intensity
- 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.
-

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
- Higher grades + faster learning
