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.
The Conconi test (Conconi 1982) is a simple method for measuring an individual's maximum, anaerobic and aerobic thresholds.
To perform the test you require
How to conduct the test
Conducting the Test on a 400m Track
Conducting the Test on a Treadmill
I have been unable to locate any normative data for this test.
Calculation of Anaerobic and Aerobic Threshold
Determine the speed for each 200 metres and then for each 200 metres plot speed versus heart rate on a graph. You will find the graph gradually rises to start with and then flattens before rising again. This flattening in the graph indicates the athlete's anaerobic threshold. In the example conconi graph below this flattening appears to be around 182pm. A good estimate for aerobic threshold has proved to be the anaerobic threshold minus 20 bpm.
Alternatively you can use the supplied Conconi AT Calculator to plot and determine the athlete's Anaerobic Threshold.
Analysis of the result is by comparing it with the results of previous tests. It is expected that, with appropriate training between each test, the analysis would indicate an improvement in the athlete's anaerobic and aerobic thresholds.
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 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. The following link provides a variety of factors that may influence the results and therefore the test reliability.
Research by Jones (1995) has shown that there is a lack of reliability in Conconi's heart rate deflection point.
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.
