Based on biomechanics analysis of table tennis players’ forehand forward loop drive

In the Olympic Games and other high-level events, the forehand forward loop technique has always played an important role. Therefore, the forward loop ball technology should be promoted and mastered. Based on biomechanics, this paper analyzes the change of the movement characteristics of the forehand forward loop shot in table tennis players. Specifically, the experimental method and statistical method were used to make an empirical study on the changes of the joint angular velocity of the upper and lower limbs of the study object. The results showed that the peak angular velocity of the shoulder joint was 14.75 ± 3.881 when hitting a backspin ball, which was higher than that of 4.2 ± 3.58 when hitting a topspin ball, p = 0.253 > 0.05. The peak angular velocity of the elbow joint was −10.97 ± 1.74, which was higher than that of the wrist joint, 5.10 ± 1.2, p = 0.537 > 0.05. The peak angular velocity of the hip joint was 6.52 ± 1.73, which was higher than that of the hip joint when hitting a topspin ball (4.84 ± 1.57, P = 0.011 < 0.05). The peak angular velocity of the knee joint was 2.20 ± 0.8, which was larger than that of the knee joint when hitting the topspin ball 2.03 ± 0.66, P = 0.231 > 0.05. The peak angular velocity of the naked joint was 1.75 ± 0.65, which was higher than that of 1.43 ± 0.54, P = 0.078 > 0.05. It can be seen that when hitting the backspin ball, the peak angular velocity and speed of the joint of the upper and lower limbs of the body are greater than that when playing the top spin ball; the peak angular velocity difference between elbow and hip joints is the largest. Therefore, when hitting the backspin ball, pay attention to the lower arm to achieve the purpose of accelerating elbow flexion. At the same time, the rotation speed of the body should be properly reduced, and the speed of the body translation should be increased so as to maximize the peak angular speed of the joint.
