The amplitude and distribution of both strain and stress in human Achilles tendon during jumping were calculated by non-linear finite element analysis with a Mooney-Rivlin model. The first principal strain over 0.2 was seen in the part with small cross sectional area and in the upper part of the calcaneus, and the maximal first principal strain exceeded 0.33. The first principal stress exceeding 100MPa was observed in the similar parts (maximum 293MPa). These parts are approximately where Achilles tendon's rupture and/or inflammation frequently occur For sub-maximal increasing load level, these parts showed larger strain and stress earlier than other part, which could be related with the non-linear material property of Achilles tendon tissue.
