Astrand & Rhyming Submaximal Test
Safety Information:
 Before the test each participant should complete a consent form
 If the participant is feeling unwell, they should not exercise
 Please ensure you have read the following Risk Assessment/s before
using this equipment or undertaking the following task/s:
o 2013.0718RA_exercise_ergometry
o 2013.0910RA_monark_cycle_ergometer_handling
o 2013.0124RA_srm_and_monark_cycle_ergometers
General Operation:
This test helps you to predict VO2max from work intensity and heart rate using
method described by Astrand & Rhyming (1954). The information contained
in this package and the data, which you collect during the sub-maximal test,
will allow you to predict VO2max for participants between the ages of 15 and 65
years.
Protocol:
1. Ensure that the participant has not eaten within the past hour.
2. Weigh the participant and record weight on the form.
The
participant should wear light clothing and appropriate training
shoes.
3. Put on a Polar Heart Rate Monitor and check that a signal is being
received.

4. Adjust the saddle height to suit the subject. There should only be
a slight bend in the leg with the pedal fully down.
5. Set an appropriate initial work load. This should be 60 watts for
women (just the basket) and 90 watts for men (basket + 0.5 kg).
Ask the participant to cycle at 60 rpm.
6. The participant then cycles at this workload for 6 minutes. Record
to the heart rate at 5 minutes and 6 minutes.
a. If the mean heart rate is between 125 and 170 beats per minute,
the test can be terminated.
b. If the mean heart rate is less than 125 beats per minute, increase
the work load by 30 watts (0.5 kg) and continue the test for a
further 3 minutes.
c. If the mean heart rate between minutes 8 and 9 is between 125
and 170 beats per minute, the test can be terminated, and so
on…
7. At the end allow the subject to keep pedalling at an easy pace with
the load removed from the ergometer, for about one minute.
8. If the heart rate exceeds the values shown in table 2 at any point,
the test should be terminated.
9. You can then read the predicted VO2max from the nomogram
shown in figure 1. To do this, draw a line between the appropriate
points on the heart rate and work rate scales (make sure you use
the correct scales for males and females!). Determine where the
line intersects the VO2max scale and apply the appropriate age
correction factor (shown on the nomogram).
