Introduce: The air pistol is a individual sport. After research, it is believed that excellent international combatants will have better performance if they stabilize the technique before firing. However, in current or training competitions, At present, there is no reliable and effective method to find problems or errors in technique or movement posture, which makes it impossible to solve and improve immediately. Research motivation:Understand the movement performance and overall development of players' skills, and at the same time make corrections and adjustments in training. This can not only increase self-confidence by knowing yourself and the opponent, but also increase the correctness and feasibility of the training direction. Therefore, application engineers established a shooting-specific force plate system to measure the shift of the center of gravity to help players achieve balance when performing shooting actions. Purpose of Research:1. Discussing the stability analysis of upper limb movement rhythm in air gun shooting technology. 2. Discussing the weight ratio and COP distribution analysis of lower limb movements technology. 3. Discussing the cycle of a shooting relationship between upper limb and lower limb. Methodology: there are 5 air pistol players subjects (1 male and 4 female) from high school Class A and Class B. The average age is 16.6±1 years old and the average height is 165.4±8.6 cm, the average weight was 62.8±10.1 kg, and the age at ejaculation was 4±1.7 years. Application air pistol shooting software program by LabVIEW2020, data acquisition card NI USB-6009, a force plate CELTRON LPS-200kg, a camera SONY FDR-AX700 4K, a tripod Velbon cx460, a computer ASUS VivoBook S, An IMU BNO085 wearable device, synchronized with serial lines, records the subject's shooting status. Results and Discussion:Shooting 10 rounds of action split time, the standard deviation of the average number of press and smash time points and the single sample test value, the action split time No1, No4, and No5 players have the same characteristics, No2 and No3 have the same characteristics; firing period characteristics: No4 player>No2 Players>No5 players>No3 players>No1 players. In the single sample test value of the average standard deviation of the action phase of the 10-shot double-foot force ratio, there are three different characteristic ratios, one for No1 and No4 players, one for No2 and No3 players, and one for No5 players. In the standard deviation of the action phase average and the single sample test value of the COP position of both feet in 10 rounds, three different COP characteristics were observed, No. 1 player offset>offset(Y)>offset(X), The No.2 player’s offset(Y)>Offset>Offset(X). The No3 and No4 players are the same as the No.2 player. The No5 player’s offset>Offset (X)>Offset(Y). Conclusion: Research results The stability of the upper limb movement rhythm in air pistol shooting technology is slightly longer during the aiming period and the rest period. In the analysis of the weight ratio and COP distribution of the lower limb movement, the sway of (X) offset is greater than the offset and offset. (Y) Obvious. In relation to movements of the upper and lower limbs, past research has shown that maintaining body balance enables the human body to perform various movements. By supporting the soles of the feet with both feet, the body is stabilized and maintained to perform a series of limb activities. Through sports science, sports events are quantified so that players and coaches can effectively observe characteristics and optimize them. Recommendations:Through the system developed by engineers, the combination of hardware and software can help find the characteristics of the player's center of gravity and pace during shooting, and observe the player's physical strength during training or competition to find out which shot the player performs. decline, or today's condition is not good, check the details so that players can improve with twice the result with half the effort. It is suggested that in the future, if researchers have the opportunity, they can collect multiple participants, or observe the characteristics of the players by shooting the number of rounds, and then classify the characteristics to form a database to help players achieve breakthroughs in performance.
