The Astrand Treadmill Test
The purpose of this test is to measure a client's aerobic fitness (the ability of the body to use oxygen to produce energy while running)
To complete this test you will require:
- A Treadmill with adjustable speed and gradient.
- A Stopwatch/clock.
- An assistant.
For this test your client starts walking on the treadmill and builds their speed up to 8.05km/hr (5 mph), with a grade (incline) of 0%. Once they are at this speed start the stopwatch and complete 3 minutes. After 3 minutes set the grade to 2.5% and complete another 2 minutes. Increase the grade by 2.5% every 2 minutes thereafter until the client is unable to continue the test.
Results: From the total running time an estimate of your clients VO2 max can be calculated by using the following formula;
VO2 max = (Time × 1.444) + 14.99
("Time" is the total time of the test expressed in minutes and fractions of a minute.)
E.G. You 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
Once you have established your clients result you can compare it to ‘normative data’ on the following tables:
