The Åstrand Treadmill Test is a valuable tool for estimating aerobic fitness levels. This test, developed by Per-Olof Åstrand in 1952, allows for a quick and accurate measurement of VO2max. By maintaining a constant running speed on a treadmill with a gradual increase in gradient every two minutes, the test provides valuable insights into an individual’s aerobic endurance.
Purpose and Equipment
The primary purpose of the Åstrand Treadmill Test is to estimate aerobic fitness levels. The only equipment required for this test is a treadmill that allows for adjustment of the gradient. Additionally, a stopwatch and a heart rate monitor can be used, but they are optional.

The test is performed on a treadmill with the speed set to 5 miles/hr (8 km/hr). The subject runs at this speed for three minutes at a 0% gradient. After three minutes, the gradient is increased by 2.5% while maintaining the same speed. This process is repeated every two minutes until the individual reaches exhaustion. The test is concluded when the athlete is unable to continue, at which point the total time is recorded.
Scoring and Target Population
To calculate VO2max, the recorded time is used in the following formula: VO2max = (time x 1.444) + 14.99. This test is beneficial for any sport that requires aerobic endurance, such as long-distance running, cross-country skiing, rowing, triathlon, and cycling.

One of the key advantages of the Åstrand Treadmill Test is that it does not require expensive VO2 analysis equipment, making it accessible to a wider range of individuals. Additionally, by monitoring heart rate during the test, it is possible to obtain a direct measurement of maximum heart rate, which can be used to set specific training target heart rate zones.
It is important to note that this test is best conducted with athletes who are familiar with exercising at high intensity. It is not recommended for recreational athletes or individuals with health problems, injuries, or poor fitness levels.
