Astrand Treadmill Test

Testing and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made but in the analysis we need to bear in mind the factors that may influence the results.

Objective

The objective of the Astrand Treadmill Test (Astrand 1952)[2] is to monitor the development of the athlete's general endurance (VO2 max).

Required Resources

To undertake this test you will require:

  • Treadmill
  • Stopwatch
  • Assistant
Treadmill

How to conduct the test

This test requires the athlete to run as long as possible on a treadmill whose slope increments at timed intervals

  • The athlete warms up for 10 minutes
  • The assistant sets up the treadmill with a speed of 8.05km/hr (5 mph) and an incline of 0%
  • The assistant gives the command “GO”, starts the stopwatch and the athlete commences the test
  • The assistant, after 3 minutes into the test, adjusts the treadmill incline to 2.5% and then every 2 minutes thereafter increases the incline by 2.5%
  • The assistant stops the stopwatch and records the time when the athlete is unable to continue

Assessment

I have been unable to locate any normative data for this test.

From the total running time an estimate of the athlete's VO2 max can be calculated as follows:

  • VO2 max = (Time × 1.444) + 14.99

where "Time" is the recorded test time expressed in minutes and fractions of a minute.

Example

The athlete stopped the test after 13 minutes 15 seconds of running (13.25 minutes).

  • VO2 max = (13.25 × 1.444) + 14.99
  • VO2 max = 34.123 mls/kg/min

For an estimate of your VO2 max enter the duration of the run and then select the 'Calculate' button.

Analysis

Analysis of the test result is by comparing it with the athlete's previous results for this test. It is expected that, with appropriate training between each test, the analysis would indicate an improvement in the athlete's VO2 max.

Target Group

This test is suitable for endurance athletes and players of endurance sports (e.g. football, rugby) but not for individuals where the test would be contraindicated.

Reliability

Test reliability refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Reliability will depend upon how strict the test is conducted and the individual's level of motivation to perform the test.

Validity

Test validity refers to the degree to which the test actually measures what it claims to measure and the extent to which inferences, conclusions, and decisions made on the basis of test scores are appropriate and meaningful. This test provides a means to monitor the effect of training on the athlete's physical development. There are published VO2 max tables and the correlation to actual VO2 max is high. For an assessment of your VO2 max check out the VO2 max normative data tables. A study by Noakesa (1990)[1] found a high correlation between the test results and running performance.

Advantages

  • Minimal equipment required
  • Simple to set up and conduct

Disadvantages

  • Specialist equipment required
  • Assistant required to administer the test
