A three-dimensional biomechanical analysis and modelling of the handstand movement in the gymnastic sports

Aim: The purpose of this study was to establish a biomechanical model to compute the force and moments acting on the joints during handstand by the link segment model. Material and Method: One male gymnast participated in this study. Using motion analyzer system equipped with four cameras (set at 120 Hz) and one force plate, the execution of balance on two hands for five seconds was recorded. The data collection frequency of the force platform was set at 120 Hz. The fifteen spherical reflective markers were placed on the anatomical landmark. By defining a five segmental model of three dimensional to four joınts through the inverse dynamic in MATLAB software, the torque for joints was calculated. Results: In summary, in this study, there are four joints in the rigid body model consisting of five limbs in biomechanical model. An average of 10 ° angular of joint of the wrist has occurred. The average shoulder angle was 6 °, hip 5 ° and elbow 3 °. Conclusions: The most angular changes and torque were observed in the wrist. The wrist has been shown to play an important role in body control during handstand. Key Words: Biomechanics, Three Dimensional Analyses, Handstand, Modelling
