| Summary: | 碩士 === 臺北巿立體育學院 === 運動器材科技研究所 === 101 === Purposes: Analysis of force reduction using a finite element method (FEM) and kinetics and kinematics effects of lower extremity landing under different wooden structures properties. Methods: 4 types of wooden structures had been tested and simulated using Berlin Artificial Athlete (BAA) and ANSYS LS-DYNA, respectively. Thirteen participants were landing on these wooden structures. During the landing process, the related-data from a force plate, high speed camera, and accelerometer were collected. A one-way ANOVA and a Pearson correlation were used for statistical analysis and α < 0.05. Results: For structural simulation, the deformation absorption ration is higher correlation (r = .985) between simulation and testing. For the landing testing, the kinematical index is no significance difference while landing on different surfaces, but all of the kinetic results had significant differences. Moreover, the strong correlations among BAA testing, FEM simulation and the landing testing were examined. Conclusions: It had high correlations among BAA testing, FEM simulation and the landing testing. Thus, a suggestion of this study is that both BAA and FEM can be used to evaluate peak ground vertical force, during time from landing to peak force, maximal loading rate, and acceleration of lower extremity while landing on different wooden structures.
