Required
resources
To undertake this test you will require:
- Treadmill where speed and
grade of slope can be adjusted
- Stop watch
- Assistant.
How
to conduct the test
The athlete runs on a treadmill to exhaustion.
At timed stages during the run the slope of the treadmill is increased as
detailed in the table below.

The treadmill is set up with a speed of
11.3km/hour(7.02 miles/hr) and a slope of 0° and the athlete commences the test. At minute
intervals during the test the slope of the treadmill is adjusted.
The assistant starts the stop
watch at the start of the test and stops it when the athlete is unable to
continue – this ideally should be between 9 and 15 minutes.
Analysis
Analysis of the result is by
comparing it with the results of previous tests. It is expected that, with
appropriate training between each set, the analysis would indicate an
improvement.
From the total running time
an estimate of the athlete’s VO2max can be calculated as follows:
VO2max
= 42 + (Time x 2)
“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 = 42 + ( 13.25 x 2)
VO2max = 68.5 mls/kg/min
Target
group
This test is suitable for endurance athletes
and players of endurance sports(soccer, 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.
VO2max
from a One Mile Jog
Using statistical techniques, Brigham Young
University(USA) scientists used the heart rates, body weights, and one mile jog
times from 54 students to create a fairly simple mathematical equation for VO2max.
They then checked the predictive power of the equation by using it to forecast
the VO2max of another 52 runners involved in the study. When these
predicted VO2max were compared with the runners’ VO2max
determined in the exercise physiology laboratory, the equation was determined
to be remarkably accurate.
Required
resources
To undertake this test you will require:
- 400 metre track
- Stop watch
- Heart rate monitor
How
to conduct the test
- Warm up by jogging for a
couple of minutes
- Jog one mile at an easy,
steady pace, making sure that you take longer(yes longer) than eight
minutes(males), or more than nine minutes(females)
- Record how long it actually
takes you to jog one mile
- Record your heart rate
immediately on completing the mile
Analysis
The algorithms to calculate your VO2max
are:
- Male athletes VO2max
= 108.844 – 0.1636W – 1.438T – 0.1928H
- Female athletes VO2max
= 100.5 – 0.1636W – 1.438T – 0.1928H
Where W=Weight
in kg; T=Time for the one mile run
and H=Heart Rate at the end of the
run.
Target
group
This test is suitable for endurance athletes
and players of endurance sports(soccer, rugby…) but not for individuals where
the test would be contraindicated.
The test result will be most accurate for
athletes aged 18-29, but older athletes can still use this test to monitor
gains in fitness and obtain a ballpark figure for their VO2max.
Reliability
Reliability would depend upon how strict the
test is conducted and the individual’s level of motivation to perform the test.
