| Shaanxi Province will hold the 14 th National Games of the People’s Republic of China in2021.The Shaanxi Provincial Sports Bureau and Xi’ an Institute of physical Education jointly organize the queue of young women in Shaanxi Province.The women’s volleyball team in Shaanxi Province has been disbanded since 1998 for more than 20 years and lacks volleyball reserve talents and a complete training system.During the volleyball match,the level of serve,spike and blocking can directly reflect the attack ability and overall technical level of a team.In order to understand the technical development level of young people today,this paper analyzes and studies the application effect of the main scoring techniques of the top eight teams in the 2018 National Sports School U15 Women’s Volleyball Championship,and trains the youth women’s volleyball team in Shaanxi Province To provide reference basis,at the same time sum up the advantages and disadvantages of young women volleyball in offensive technology,and combined with the knowledge of volleyball theory,put forward targeted suggestions for the training and competition of young women volleyball.Research methods: using literature method,expert interview method,single factor ANOVA variance analysis of mathematical statistics,for the failure to pass the variance homogeneity test(P>0.05),the model was adjusted,the Tamhane test was used to compare two pairs,and the main score technology application effect of the 2018 National Sports School U15 Women’s Volleyball Championship was analyzed.Results :(1)The correlation between competition achievement,technical achievement and quality achievement is significant,among which the correlation between competition achievement and technical achievement is most significant.(2)There is no big difference in the overall effect of the serve,mainly in the float and jump,with less use of the front hand,and no significant difference between the service score and the service error rate(P>0.05).There were significant differences between the highest and lowest serve scores.The service scores of Shijiazhuang Sports School and Suzhou Sports School were significantly higher than those of Zhangzhou Sports School at 0.01 confidence level and higher than those of Yunnan Sports Vocational College at 0.1.service error rates were different between individual teams.the service error rates of Zhangzhou Sports School and Suzhou Sports School were significantly higher than those of Jinan Sports School and Ganjingzi Sports School(P<0.1).Shijiazhuang Sports School,Jinan Sports School serve effect is the best,Suzhou Sports School serve effect is general,Zhangzhou Sports School serve effect is poor.(3)The whole application effect of each team is better,the counter-attack is more than one attack,the main thrust of the spike is 4 and 2,the number of attacks is the most,followed by 3 near-body fast ball,attack times more than 2;the score rate and error rate difference is not significant(P>0.05),did not pass the homogeneity test of variance.Zhangzhou SportsSchool and Jinan Sports School have the best attacking effect,Shijiazhuang Sports School has the average attacking effect,and Yunnan Sports Vocational College has poor attacking effect.(4)There is a big gap in the application effect of each team blocking,mainly single blocking and double blocking,and the difference of each team blocking scoring rate is relatively significantly(P<0.05),at the confidence level of 0.1,both Zhangzhou Sports School and Jinan Sports School were significantly higher than Suzhou Sports School;Fuzhou Sports School was significantly higher than Ganjingzi Sports School,Shijiazhuang Sports School,Suzhou Sports School,Yunnan Railway Vocational College;Changxing Sports School was significantly higher than Suzhou Sports School;and the error rate of each team blocking was not significantly different(P>0.05).The blocking effect of Fuzhou Sports School and Zhangzhou Sports School is the best,and that of Ganjingzi Sports School and Suzhou Sports School is poor.Conclusion :(1)The level of physical fitness affects the development of basic technology to a certain extent,and the level of technical application also determines the overall score ranking.(2)The effect of serving is better in Jinan,Shijiazhuang and Ganjingzi Sports School,while the other teams are generally used,the more stable team is not aggressive enough,and the more aggressive team is not stable enough.Teenage women’s volleyball team mainly to the hair float ball,the front hand float ball use less,jump hair float ball score rate is the highest,the effect is the best.(3)The effect of each team’s spiking is better,among which anti-attack More than one attack,one attack button the best effect,high scoring rate.The main attack points of each team are the strong attack of position 4 and the fast attack of position 3.The scoring rate of position 3 in one attack is the highest,and the score rate of position 4 in counter attack is the highest.(4)The effect of blocking the use of the first three better use,the latter five teams poor use.The main use of double blocking and single blocking technology,single blocking effect is the best.In the double blocking,the invalid blocking is mostly due to the hand type,the strength of the blocking and the flexibility of the foot,and the cooperation between the players is not enough.(5)There is a large gap between the main team and the substitute in the top eight teams.The main players are skilled in the use of technology,for the team’s main scorer,deal with all kinds of key goals;the use of substitute technology is not skilled,easy to cause mistakes in the game. |
