Assessing General Endurance (VO2Max) with Astrand Treadmill Test

The objective of this Astrand Treadmill Test is to monitor the development of the athlete's general endurance (VO2max).

Required resources
To undertake this test you will require:
  • Treadmill where the speed can be set at 5 mph (8.05 km/hr) and grade of slope can be adjusted
  • Stop watch
  • Assistant.
Astrand Treadmill Test
How to conduct the test?
  • The treadmill is set up at the start with a speed of 8.05km/hr (5 mph) and a grade of slope of 0%
  • The athlete commences the test
  • After 3 minutes the grade is set to 2.5% and then every 2 minutes the grade is increased by 2.5%
  • The assistant starts the stop watch at the start of the test and stops it when the athlete is unable to continue.
Analysis
Analysis of the result is by comparing it with the results of previous tests. It b expected that, with appropriate training between each test, the analysis would indicate an improvement.
From the total running time an estimate of the athlete's VO2max can be calculated as follows:
  • VO2max = (Time x 1.444) + 14.99
  • "Time" is the total time of the test expressed in minutes and fractions of a minute.
Example:
The athlete stopped the test after 13 minutes 15 seconds of running (13.25
minutes).
  • VO2max = (13.25 x 1.444) + 14.99
  • VO2max = 34.123 mls/kg/min.
Target group
This test is suitable for endurance athletes and players of endurance sports (eg football,  rugby)  but  not  for  individuals where the  test  would  be contraindicated.

Reliability
Reliability would depend upon how strict the test is conducted and the individual's level of motivation to perform the test.

Validity
There are published VO2max tables and the correlation to actual VO2max is high.
