Astrand Treadmill Test
The objective of the Astrand Treadmill Test (Astrand 1952)[2] is to monitor the development of the athlete's general endurance (VO2 max).

Required Resources
To undertake this test you will require:
1. Treadmill
2. Stopwatch
3. Assistant

How to conduct the test
This test requires the athlete to run as long as possible on a treadmill whose slope increments at timed intervals
1. The athlete warms up for 10 minutes
2. The assistant sets up the treadmill with a speed of 8.05km/hr (5 mph) and an incline of 0%
3. The assistant gives the command “GO”, starts the stopwatch and the athlete commences the test
4. The assistant, after 3 minutes into the test, adjusts the treadmill incline to 2.5% and then every 2 minutes thereafter increases the incline by 2.5%
5. The assistant stops the stopwatch and records the time when the athlete is unable to continue

Assessment
From the total running time an estimate of the athlete's VO2 max can be calculated as follows:
VO2 max = (Time × 1.444) + 14.99
where "Time" is the recorded test time expressed in minutes and fractions of a minute.

Example
The athlete stopped the test after 13 minutes 25 seconds of running (13.25 minutes).
VO2 max = (13.25 × 1.444) + 14.99
VO2 max = 34.123 mls/kg/min

Analysis
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.

Target Group
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.

Reliability
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.

Validity
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. This test provides a means to monitor the effect of training on the athlete's physical development.

Astrand Treadmill Test Tutorial Application Use

After doing a astrand treadmill test, then obtained the result of time in minutes that must be incorporated into this application.

In this application there are 2 kinds of fitness calculations
1. Calculation for 1 person
2. Calculation for 10 people

Two kinds of calculations are actually the same in the process of determining the fitness level from the astrand treadmill test, the difference is only in the amount of data entered.

In the calculation for 10 people, users can also enter data only 5 people. The rest is emptied.

The data that the app user should enter is
1. Name
2. Age
3. Sex
4. Time in minutes

After the user enters the data, please click the PROCESS button to find out the results of each individual's fitness calculation.

If you want to store data that has been calculated, please click SAVE button.

If you want to delete data that has been entered on the data input page please click CLEAR button.

If you want to see the data that has been saved before please click the DATA button.
