| Nowadays,the technology of shooters around the world is continuously improving and tends to improve,and the gap in technology is gradually narrowing.In addition to possessing superb specialized skills,high-level shooters need to possess strong physical fitness.The level of competitive ability is closely related to physical fitness.As one of the core elements of athletes’ competitive ability,physical fitness plays a crucial role in improving their competitive ability.Although China’s flying saucer shooting has achieved some achievements in recent years,the only valuable Olympic gold medal was won by female athlete Zhang Shan at the 1992 Barcelona Olympic Games,and the female flying saucer two-way shooting is currently the best performance in the flying saucer shooting event,and it is also the most promising historical breakthrough in the Olympic Games.Based on this,and using the opportunity of the author of this article to engage in physical training for the national flying saucer shooting team,on the basis of a full understanding of the characteristics of the project,and in combination with the physical training practice during the preparation for the Ketordia World Championships and the Asian Championships,to construct a physical fitness evaluation system for excellent female flying saucer two-way shooters in China,which has important significance for improving the physical fitness training level of Chinese female flying saucer two-way shooters.This paper takes the physical fitness evaluation indicators of China’s elite female flying saucer two-way shooters as the research object,mainly adopts the methods of expert interview,Delphi method,test method,mathematical statistics,etc.After selecting the primary indicators determined by expert interview through Delphi method,it uses the method of factor analysis to optimize the relevant indicators,and calculates the relevant weight coefficient of each indicator,The physical fitness evaluation index system of China’s excellent female flying saucer two-way shooters is constructed;The system evaluation criteria are established through the percentile method,and the following conclusions are drawn:(1)The evaluation system of the physical fitness index of the excellent female flying saucer two-way shooter is constructed,which mainly includes four first-level indexes: body shape,body function,body quality,and movement mode;9 secondary indicators;Length,fullness,cardiopulmonary function,aerobic capacity,strength,speed sensitivity,endurance,basic action mode and special action mode;Ten third-level indicators: arm stretch,Ketolet index,quiet heart rate,maximum oxygen uptake,arm bending and hanging,straight edge falling,one-minute two-handed tennis ball throwing against the wall,gun control,deep squat,left and right rotation with gun.(2)Established a physical fitness evaluation model for excellent female flying saucer two-way shooters: Y(athlete’s physical fitness level)=0.048 × Arm span+0.036 × Ketolet Index+0.051 × Quiet heart rate+0.057 × Maximum oxygen uptake+0.026 × Bent arm suspension+0.021 × Straight edge drop+0.026 × 1 minute two-handed wall tennis throw+0.026 × Gun control+0.065 × Squat+0.057 × Turn around with a gun.(3)The percentile method was used to establish the physical fitness evaluation standard table of excellent female flying saucer two-way shooters,which was divided into five grades:A,B,C,D and E.The comprehensive evaluation criteria are: A is>5.94,B is>5.28-5.94,C is3.86-5.28,D is 2.86-<3.86,E is<2.86.The evaluation criteria table is convenient for scientific and reasonable diagnosis of the physical development level of women’s flying saucer two-way shooters in the future. |
