KINEMATIC OF THE TAKEOFF PHASE OF THE LONG JUMP: A COMPARISON OF TWO DIMENSIONAL AND THREE DIMENSIONAL ANALYSES

24527

The purpose of the study is to determine the analyse protocols by analysing the segment lengthsusing kinematics parameters that result of the 2 and 3 dimensional analysis of takeoff phase in the long jump. An elite long jumper participated in this study (Height = 1.75 m, Weight = 75 kg). Four high-speed cameras operating at 100 frames per second were used to record the long jumper’s attempts (Basler A 602f high speed camera). Captured 2 and 3 dimensional views digitized in SIMI Motion 7.3 (SIMI Reality Motion Systems GmbH-Germany) by tracking 8 anthropometrical markers. Segments lengths were calculated in 2 and 3 dimensional respectively. As a result; the amount of error between the real segment length and computed segment length using kinematics parameters of 2 and 3 dimensional analyses, 3 dimensional analyse results showed least error than 2 dimensional analyse. As 2 dimensional analyse results compared to each other; the camera was placed in perpendicular the motion plane showed least error than the camera placed with an angle to the motion of plane.
