Astrand 6-minute Cycle Test
Testing and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made. In the analysis, we need to bear in mind the factors that may influence the results.
The Astrand 6-minute Cycle Test was devised by Astrand P.O. in 1956.
The objective of this test is to monitor the athlete's VO2 max.
How to conduct the test
1 watt is equal to 3600 J/hr, or 6.1183 kg-m/min
If the estimated values are 0.00, then the values you entered are outside the specified ranges, and you will need to use the Astrand-Rhyming Nomogram (PDF copy) to obtain your estimates.
For an analysis of your VO2 max score see the VO2 max page.
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.
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.
Test reliability refers how 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. The following link provides various factors that may influence the results and therefore, the test reliability.
Test validity refers to the degree to which the test measures what it claims to measure and the extent to which inferences, conclusions, and decisions made based on test scores are appropriate and meaningful. This test provides a means to monitor training on the athlete's physical development. There are published VO2 max tables, and the correlation to actual VO2 max is high. For assessing your VO2 max see the VO2 max normative data tables.
