Biomechanical analysis of the 626b technique in China's elite male platform divers

Abstract

This study employed methods such as literature review, expert interviews, video analysis, and mathematical statistics to conduct a comparative biomechanical analysis and diagnosis of the 626B maneuver performed on the 10-meter platform by elite Chinese divers Qiu Bo, Yang Jian, Huo Liang, and Xie Siyang. The results indicate that during the buffer phase, smaller elbow and knee joint angles along with a larger shoulder joint angle contribute to generating greater angular momentum. At the moment of takeoff, a smaller reduction in the shoulder joint angle and a larger takeoff angle are more conducive to increasing the height of the jump. During the execution of the half to one-and-a-half somersaults, achieving a "counter-rotation" between the torso and lower limbs helps the body rapidly reduce the moment of inertia and increase the rotational speed.
