Assessing Aerobic Capacity

This page of resources is designed to support the delivery of workshops and labs on aerobic capacity testing and the completion of related lab reports and essays.

Study Questions

A series of questions to consider in relation to practical sessions and prior to writing related lab reports:

Define the following terms: maximal oxygen consumption, ventilatory threshold, lactate threshold.
Identify and explain the concept of contraindications when supervising a test of aerobic capacity.
How can test data be used to inform subsequent training programme design?
Describe the ways in which the measurement of maximal oxygen consumption can be useful when working with an athlete.
When might it be inadvisable to undertake a maximal test of aerobic capacity and what alternatives are available?
Discuss the differences between various measures of aerobic capacity and which are more or less valid (what does validity mean in this context?)
What role does Lactate play in the body (Brooks, 2018)
What is running economy and how is it useful? (e.g. Barnes et al, 2018)
Explain the criteria for determining whether VO2max was attained during a graded exercise test. (see Poole & Jones, 2017; Midgley et al, 2008)
What are skeletal muscle determinants of endurance performance? (see van der Zwaard et al, 2021)
What are the potential effects of different protocols on outcome measures (e.g. VO2max, LT etc).
Discuss the range of methods used to analyse and assess LT once data has been collected in an incremental test.
What is Critical Power and how can it be used to evaluate an athlete's potential? (see Jones & Vanhatalo, 2017, Poole et al, 2016, see podcast at bottom of page). What are the potential criticisms?
What is the Anaerobic Threshold and why is it controversial (Poole et al, 2020)

Critical Power and VO2 kinetics with Mark Burnley, PhD | Scientific Triathlon | EP#257

Episode link https://scientifictriathlon.com/tts257/ or listen below

Mark Burnley, PhD, is an exercise physiologist at the University of Kent. Mark's main research interests include oxygen uptake (VO2) kinetics, where an important application is how to optimally use warm-ups, as well as Critical Power, which forms the transition point (or transition area) between the heavy and severe exercise domains. Because of the non-steady-state nature of exercising above CP, it has significant importance in a large number of training and racing applications.

In this Episode you'll learn about:

VO2 kinetics - what does it mean?
The fast and slow components oxygen uptake
Heavy priming exercise and its effects on VO2 kinetics (or the importance of a good, specific warm-up)
Critical Power (CP) - what is it and how does it compare to other "threshold concepts"
How to assess CP and use it in training
How fatigue develops differently in the different exercise intensity domains (moderate, heavy, severe) and interventions to minimise fatigue
