We are all aware of different research phases (proof of concept, development of characteristic model, evaluation of characteristic model and confirmation or rejection of a hypothesis on a larger population) that most research in the field of biomechanics has to undergo. However, in order to conduct quality and successful research, methods and tools with low variability of measured results should be used. Most of the research in the field of biomechanics or more specifically in the field of skeletal muscles status was undertaken by methods and tools that had a rather high rate of variability. That is why the results could be misleading thus taking the research in the wrong direction. Tensiomyography or shorter TMG is a highly objective method of muscle diagnostics with a scientifically proven low variance of 5% that facilitates new areas of research in the field of biomechanics. Furthermore, as measurements result in numerical data, the results are easier to process and analyze.
