＜正＞ The purpose of our study was to investigate kinematical parameters of tail movements in captive Ateles geoffroyi during brachiation. In suspensory locomotion the prehensile tail of New World monkeys acts as a third extremity beside the two arms. Taking the complex anatomy of this multi joint organ into account, its successful grasping is, necessarily, based on costly neuronal control. Quantifications of extents of tail movements might allow clarifying, how the tail is able to cope, most economically, with

Background:Numerous studies about the interaction between footwear(and barefoot) and kinematic and kinetic outcomes have been published over the last few *** studies however lead to the conclusion that the assumed interactions depend mainly on the subjects" experience of barefoot(BF) walking/running,the preferred running strike pattern,the speed,the hardness of the surface,the thickness of the midsole material,and the runners’ level of *** aim of the present study was to investigate lower leg kinematics o\’ BF running and running in minimal running shoes(MRS) to assess comparability of BF kinematics in both *** systematically compare both conditions we monitored the influencing variables described above in our measurement *** hypothesized that running in MRS does not alter lower leg kinematics compared to BF ***:Thirty-seven subjects,injury-free and active in sports,ran BF on an EVA foam runway,and also ran shod wearing Nike Free 3.0 on a tartan indoor ***-leg 3d kinematics was measured to quantify rearfoot and ankle *** markers were used in both shod and BF ***:All runners revealed rearfoot strike pattern when running *** between BF and MRS running occurred particularly during the initial stance phase of running,both in the sagittal and the frontal *** running revealed a flatter foot placement,a more plantar flexed ankle joint and less inverted rearfoot at touchdown compared to MRS ***:BF running does not change the landing automatically to forefoot running,especially after a systematic exclusion of surface and other influencing *** Nike Free 3.0 mimics some BF ***,changes in design of the Nike Free should be considered in order to mimic BF movement even more closely.
