OBLA Test

The OBLA Test is part of the performance diagnostics programme for amateur-, competitive- and high-performance-sports athletes carrying out endurance related exercise. It is primarily designated to analyse the aerobe endurance performance but also secondly to appraise the anaerobe performance as the test is carried out until the full physical capacity of the test person elapses. The physiological test parameters “lactate concentration in the peripheral blood”, “heart rate curve” and sometimes the test person’s ventricle factors “oxygen uptake” and “carbon dioxide release” are monitored and included in the analysis. Regular testing comparing actual and previous results gives information about the efficiency of the respective last training unit. It is common practise to adapt the training intensity of endurance athletes according to the results of the OBLA Test.


The Cyclus2 is the ideal device for testing. Here are the facts:

Excellent specific characteristics in performance diagnostics

OBLA Test

The Cyclus2 is easily adaptable to specific cycling disciplines and therefore a first choice for cyclists, mountain-bikers, triathletes, hand-bikers. It is a professional hi-tech test device for virtually everyone concerned with cycling and even more so as the own bike can be fitted and plugged into the Cyclus2. The innovative technology simulates the most accurate and realistic scenarios by providing the biochemical conditions to work exactly the same groups of muscles during the test as in practise or competition.

Freely selectable load schemes (level protocols)

OBLA Test

The Cyclus2 provides the common cycling load schemes in the configuration of the level test as well as the option to customise any desired load scheme. The level duration can be set either as time, distance or work. The user can configure a defined post- performance (relaxation) phase, which allows analyses of the recreational heart rate.

The load at each level is precisely set and kept constant irrespective of the cadence. All significant parameters can be monitored and verified by the test person and the sports medical scientist during the ergometry.

Direct and individual analyses of the OBLA tests

OBLA Test

The Cyclus2 offers direct automatic and individual analyses of the OBLA tests in form of lactate power curves (LPC) and threshold value calculations. The lactate power curve can be calculated and rendered as exponential function, 3rd degree or 4th degree polynomial or spline. The following evaluation models are available on the Cyclus2: Mader model, Kindermann model, Dickhuth model, Stegmann model, arbitrary discrete thresholds and thresholds on arbitrary tangents (Winkel model). In addition to that the heart rate threshold values PWC130, PWC150 and PWC170 are measured and recorded.

The results are shown on the display and can be printed in form of an elegant protocol or saved as PDF file. The data can be easily stored e.g. on a USB stick. The lactate measurement data can be either imported from lactate measurement devices (e.g. Lactate Scout or BIOSEN) or manually entered and allocated to the actual load level.

Mobile performance diagnostics

The Cyclus2 is very easily and quickly disassembled and stored in a compact transport case and therefore perfectly suited for mobile performance diagnostics in training camps or during expeditions. The Cyclus2 offers a battery-powered option for mobile use on request.

Ergospirometry

The Cyclus2 can be easily embedded in other test equipment- e.g. ergospirometry-systems. This is ensured through the support of standard interfaces and standard protocols.
