Lode BV Excalibur Sport
Intended Use
A Lode ergometer is a diagnostic tool intended to be used as a stress test device in a medical
environment. The main goal of the use of a Lode ergometer is to create reproducible stress
tests. The following parameters can be measured:
Workload (watt)
Revolutions per minute (rpm)
Time (minutes and seconds)
Distance (km)
Optional: Blood Pressure (mmHg)
Optional: Heart rate (beats per minute)*
Optional: Energy (KiloJoules)
Optional: SpO2
In combination with other diagnostic tools, like ECG or pulmonary function equipment, other
important physiological data can be obtained, allowing a physician to evaluate a test subjects
physical status.
A Lode ergometer is designed both for manual operation and for control by external ECG-,
pulmonary equipment. In combination with optional software, the ergometer can also be
controlled by a PC.
The ergometer has to be operated under the supervision of well-trained medical specialists,
like cardiologists, pulmonologists and physiotherapists. The ultimate judgment whether a test
subject should undertake a stress test with an ergometer and which protocols should be used
must be made by the responsible medical specialist, based on the limitations of each
individual, the medical history and all other applicable circumstances. Neither Lode BV nor
its distributors assume any responsibility for the final use of its equipment.
* Warning
The signal of the Polar belt and receiver may be disturbed by external equipment. Therefore,
it is recommended to check the surroundings and switch off or remove the source of the
disturbance.
Contra Indication
The Excalibur Sport ergometer is to be operated by classified personnel only. As stated in the
intended use, the Excalibur Sport is intended to be used in a medical environment. During the
intended use the test subject will deliver energy. Application of the wrong dosis of energy
could lead to permanent damage of the test subject health.
Maintenance
The Excalibur Sport should be calibrated once a year. In case any damage is observed of the
Excalibur Sport Lode B.V. or his representative should be informed in order to execute the
necessary repair(s). Service of the Excalibur Sport is restricted to factory-trained personnel
only.

1Introduction
Congratulations on your new Excalibur Sport ergometer! This device will provide you
optimal test possibilities. Your test subject will also enjoy using the Excalibur Sport (for its
silent operating circumstances and its adjustability). The Excalibur Sport has standard
possibilities for adjusting the workload of the ergometer. The basic Controller has one display
to read out Workload, RPM, Heart rate (if option 928826 is available), Torque, Timer and
Distance. The Controller can be upgraded with an automatic blood pressure module (option
928818). This enhances the possibilities for controlled ergometry.
The Excalibur Sport ergometer is especially designed to test professional athletes. The
horizontal and vertical adjustability of the saddle and handlebar makes exact and optimal
positioning possible. Besides the high performance aerobic tests, the Excalibur Sport can be
used for the anaerobic Wingate sprint test with the optional software package. Standard toe-
clips are supplied which can be easily changed for the commercial available clip systems.
Another feature of the Excalibur Sport is that it offers possibilities for communication with a
range of other products (e.g. ECG devices, pulmonary function testing equipment).
1.1 Definition of terms
Hyperbolic Ergometry: The name hyperbolic ergometry refers to the curve between the
pedaling speed (RPM) and the torque (T). This curve has the shape of a hyperbole (see Fig. 1
Hyperbolic ergometry). As a result from this hyperbolic relation the workload (W) is
independent of the RPM in a special area (see Fig. 2).

Linear Ergometry: RPM dependent ergometry. The linear relation is determined by the
relation between the torque (T) and the pedaling speed (RPM) (see Fig 3). As a result of this
linear relation the workload (W) is RPM dependent (see Fig. 4 Linear ergometry ). This
means the faster the test subject is cycling, the higher the delivered workload. The linear
braking principle is usually used in mechanical ergometers.

P
RPM
Linear Factor: the default value at the start of an exercise test. The formula that expresses
the relation between RPM and Workload (P) is:
P = α* RPM5
Where αis a linear factor (= 0.044 in the Excalibur Sport). During programming a protocol
the αis adjustable.
Fixed Torque Ergometry: In this case the torque is kept constant during exercise resulting in
a linear relationship between the Workload (P) and RPM (n):
P = c * n with c = 2*π*T
With the constant c defined as:

Isokinetic ergometry: In this case the rpm is kept constant during exercise resulting in a
linear relationship between the Workload (P) and Torque (Nm).
The rpm can be adjusted, this mode can be used to define the optimal rpm.
