Testing with Ergomedic 831 E
The versatility of the 831 E Ergometer enables it to
be utilized in a variety of testing environments. The
precision and reproducibility of measurements made
with the ergometer in conjunction with the ease of
testing, allow it to be employed in clinical exercise
stress facilities, corporate fitness programs and health
clubs. The backgrounds of both the individuals being
tested and those administering the test may be vastly
different in these widely varying testing situations.
In general, whether in a clinical laboratory or a
health club, the test subject may be exercised quite
strenuously, depending on workloads which have
been selected. As a precaution, it may be advisable,
prior to beginning an exercise protocol, that each test
subject consult with a physician. Before testing, the
operator should review the entire protocol operation
with the test subject, explaining the work which will
be required and the duration of the procedure. A
system of communicating fatigue, chest pain or other
abnormal physical response to the exercise should be
discussed.
The test subject should not engage in heavy physical
activity for several hours prior to testing to establish
maximum oxygen consumption. In addition, all
testing and exercise protocols should be performed a
reasonable time after meals. The test subject should
also refrain from smoking within an hour of the
testing period.
The test subject should be prepared for using the
ergometer, including the selection of proper clothing
which neither interferes with the physical activity nor
endangers the health of the subject. The test subject
may need some education concerning the cranking of
the ergometer.
The operation of the speed metronome and over/under
display should be reviewed. The maintenance of the
proper speed should be practiced at a low workload.
Finally, the chestbelt should be applied and monitored
to check for proper heart rate operation. The baseline
heart rate may also be of assistance in determining
the nervousness of the test subject. The test subject
should exhibit a relatively stable resting heart rate
prior to starting the protocol.
Power calculation
1 rpm = 6 m on the flywheel brake surface.
50 rpm = 300 m
2 kp force makes 2 x 300 = 600 kpm/min
100 rpm= 600 m
1 kp force makes 1 x 600 = 600 kpm/min
(watt = rpm x kp)
