This study aims to identify the characteristics of the takeoff and landing in the round off performance followed by followed by a double back tuck. One gymnast participated in this study, and the data was captured using an camera at a speed of 240 fps and perpendicular to the plane of movement. Data were extracted using the analytical software SkillSpector and Kinovea. The data revealed that the vertical velocity, which was when takeoff (5.9 m/s). This was evident at the maximum height of the center of mass, which was measured (2.3 m). The higher values for the maximum height of the center of mass were the result of a combination of several performance factors, such as the contact angle and the takeoff on the floor with horizontal and faster leg extension. The horizontal velocity at contact was (5.7 m/s) and decreased to (-2.5 m/s) at takeoff. The results of the study indicate that the double back tuck movement involves a reduction in horizontal velocity and an increase in vertical velocity. This is because the horizontal velocity is converted into vertical velocity to raise the body to a great height so that the gymnast can get the time required to execute the skill while flying in the air. The leg muscles also played the dominant role in takeoff and landing through contact angles and takeoff and landing.
