Examples of indications for the use of CON-TREX systems in scientific research:

• Analysis of reliable and valid parameters for the evaluation of different muscular capacities,  such as maximum force, muscle endurance, rate of force development.

• Evaluation of different training and therapy concepts according to their efficacy on different strength capacities.
• Analysis of standardised muscular stress reactions to concentric, eccentric and reactive loads.
• Differentiation between isokinetic, isotonic and ballistic loading of all joints of the extremities and the spine.
• Combination of strength exercises and analysis of the muscular activity (combination with EMG-measurements).
• Developement of evidence-based valid training protocols for randomized (longitudinal) trials  (in training, therapy and prevention).
• Standardised application of muscular stress to evaluate metabolic and cardio-circulatory reactions.

Advantages for scientific applications:

• Objective, highly reliable and valid adjustment of dynamometer, adapter and seat.
• Settings of the subjects positioning stored in the software.
• Easy transfer of data into MS Excel spreadsheets or other programs for statistical evaluations.
• Graphical display of test results. Customisation of analysis- and evaluation protocols to individual requirements.
• Combined examination of force capabilities and muscular activities (EMG). Triggering of EMG-activities at defined sites of range of motion.
• High degree of objectivity, reliability and validity at slow as well as high velocities (by the use of the CON-TREX unique ballistic mode) for isokinetic, isotonic and isometric loads. Possibility to combine different work modes in all protocols.
• Combination of single- and multiple joint movements in testing and training. Increase of sensory motor requirements by fixation / open up of individual degrees of freedom in several joints.
