This paper presents an overview about results of mechanical testing of human tendon. We are dealing with the main function of tendon and touching on typical insurance of tendon and reconstruction of them. Since the material characteristic of tendon and dynamic models of them are not known there was made a lot of uniaxial tension test and based on measuring results built up a linear lumped model for dynamic simulation using the synthesis method. As results we can already provide quantitative data about mechanical bearing capacity of tendon beside known qualitative categories. Paper shows a well working fixing technology for tendons during tension test.
