Abstract: As a band that connects muscles with bones, tendon plays an important role in sports training. Tendon fa-tigue is closely related to its biomechanical properties. In fatigue experiment, there is a certain relation between the time required for a tendon to rapture or the number of times of circulative tension and the acting stress and/or strain as well as frequency magnitude, specimen length and temperature; a high stress tendon is easier to fatigue than a low stress tendon. Within a certain extent, the fatigue of a tendon is in accord with the stress it is subjected to; ap-propriate kinetic stimulation can improve its fatigue condition via the change of mechanical properties.
