Kinematic Comparative Study On China’s Excellent Man Cricket Pitchers’ Fast Ball Technology

The cricket pitch technology is the soul of the whole defense technology, and it is the mainsign of the measure of the strength in a team. A good pitching hander can put the hitter out of thegame directly,inhibit the attackers score. This study put he eight China excellent man cricketfast pitche in the May2011in shenyang sports, using the literature material method, expertinterview, camera analytical method, mathematical statistics and comparative analysis and othermethods, this study analyse ood athletes for the rapid cricket ball technical movement in ourcountry.The aim is to summarize the technical features of the pitcher, for our country cricketshots of the athletes fastball pitcher scientific training to provide the reference. The analysis thatthe following conclusions:1The eight excellent man cricket pitch stage HuiBei pitcher the total time is the average of0.19s, among them LvJin and yudong used the shortest, respectively is0.11s and0.14s;XiLiXin, LiDing and LianSongYu use for a long time (average is0.25s) and how they throwinga slow speed, which directly affect the ball moves when speed.2The eight excellent man cricket in the whole process of pitching pitcher has its owncharacteristics and the habit of pitching, pitching but in the process of the change in velocity andeach key points of the same basic transfer order momentum.3The eight excellent man cricket fastball gap are different in the velocity, the average is30.6m/s, the fastest velocity is ZhangQiRui,32.4m/s, followed by yudong and XuChunYang,two people’s velocity are31.8m/s, velocity is the lowest LiDing and LvJin Di, were28.9m/sand29.1m/s, reflect the different level of training and pitcher sports ability.4The eight excellent man in the last HuiBei pitcher cricket pitch phase of throwing armangular velocity and throwing arm shoulder hip in the average of the angular velocity were1195.7°/s and494.8°/s. Among them, the ball moves moment, ZhangQiRui, LianSongYu,XuChunYang and YangYuSong shoulder more angular velocity; ZhangQiRui, XiLiXin andLianSongYu hip angular velocity is larger.5The this study found that the longer the pitch at every step long, the lower focus, and themore stable body, the better to control your body quality pitches; Larger takeoff at every steplong, can make the body to accelerate forward further distance, to increase the speed of bodygravity, also improve threw the ball speed. Eight cricket pitch at every step of the pitcher long average is1.16m, accounting for63.8%on average height percentage; Eight cricket pitcher ofthe takeoff at every step long average of1.70m, and93.3%on average percentage of height.
