Methods: The study included two methods, one was simulated and verified, the others was functional testing. 18 wooden structures that overall dimensions are 0.9*0.6 m, had been tested using BAA that accords EN 14908:2005. FEA method also simulated with same wooden structures. 12 participants acted vertical CMJ on 18 wooden structures sequentially. The kinematics, includes knee and ankle joint angles, and kinetics includes ground reaction force, electromyography of lower-limb, were analyzed by one-way ANOVA. Results: There had higher correlation (r = .964) between BAA and FEA. Kinematics and electromyography of lower-limb were no significant, but ground reaction force reached significant .Conclusions: FEA and BAA and kinetics can be used to evaluate peak ground vertical force, and EMG of lower-limb when landing on different wooden structures.
