A Study On The Optimization Of Spatial Utilization Ability And Training Methods Of Football Players Aged 9 Years And 11 Years

The main results are as follows:(1)through the interview with the coach of the juvenile football team,the training methods are 1v1 practice(no antagonistic catch shooting exercise,antagonistic space passing practice and bottom training without confrontation),2v2 practice means(with antagonistic 2v2 practice,no antagonistic 2V2 using spatial relay practice),and the training method is as follows:(1)through interviews with the coach of juvenile football team,the training methods are as follows:shooting without antagonism and shooting without confrontation.3v3 practice(3V3 in rectangular area(divided into 4 squares),3V3 two groups of players in rectangular area(randomly placed 10 marking buckets in the area),4v4 practice(in rectangular area,in the rectangular area,in 12 sub-rectangular area,two groups of teams);4v4 practice means(in the rectangular area,in the rectangular area.The member also carries on the pass and catch the ball practice);the 8v8 practice method.(2)from the test results after the experiment,it is found that the number of successful transfers and the number of successful stops after the experiment are higher than those before the experiment,and the quality of the players is also better than that before the experiment,which indicates that the training method used in this experiment is of great help to improve the antagonistic personal ball control ability of the athletes,and can improve the antagonistic personal ball control ability of the athletes to a great extent.(3)the experimental group and the control group passed the matched sample T test before and after the experiment,and there was significant difference between the experimental group and the control group(0.042,0.026,0.0).34,0.044,0.023,0.033,0.014,0.048,0.043,0.028).This fully reflects that the training method used in this experiment is helpful to improve the technical application and success rate of 2v2 cooperation of 9years old 11-year-old footballers,and can increase the number of side-to-side transfer and back cover in the players.From the increase of the number of these indicators,it reflects the increase of the ability of the players to create and use space,the improvement of the success rate,and the improvement of the technical level of the players.(4)there are significant differences between the above indexes before and after the experiment.Author(except the second and last ones)The last index is not significant because the index itself is a score,while the score in a football match is poorly identified.Generally speaking,through the training methods used in this study,the formation of the middle way cooperation in the process of 3v3 and the cooperation with the sideline players,the middle road cross transposition and other indicators all have an upward trend,thus reflecting the continuous enhancement of the ability of the players to create and make use of space in the process of 3v3.(5)through the comparison of the observed indexes before and after the experiment,it can be seen that the Sigvalue of the bilateral test of all the indexes is respectively 0.582,0.665,0.214.The results show that the 4v4 training method used in this study improves the players' awareness of running without the ball and the ability to find defense line space andmake use of their timing on the court.
