Research On The Technical Effect And Comprehensive Evaluation Of The Chinese Women’s Seated Volleyball Team And Their Main Opponents In The Tokyo Paralympic Games

Research purpose: By counting the differences in technical indicators between Chinese women’s seated volleyball and their opponents in the Tokyo Paralympic Games,scientifically evaluate and analyze the teams participating in the Tokyo Paralympic Games and then rank them,and find out the difference between Chinese women’s seated volleyball and their main opponents.The difference between the two will help to further improve the technical level of Chinese women’s seated volleyball.Research methods: This paper uses the literature method,video observation method,mathematical statistics method,Delphi method and other research methods,combined with the 2020 Tokyo Paralympic Games video,to the effect of the application of offensive and defensive technology in the Chinese team’s competition with its opponents Perform statistical and comparative analysis.Research results:(1)The Chinese team’s service scoring rate is 13.48%,the error rate is 2.96%,and the service Vote value is 239.08 points;the first-attack scoring rate is41.44%,the error rate is 10.50%,the first-attack Vote value is 274.59 points;the anti-reverse scoring rate is 45.38%.The error rate is 11.34%,and the anti-reverse Vote value is 290.34 points.(2)The Chinese team’s receiving and serving rate is 36.12%,the error rate is 6.08%,and the receiving and serving Vote value is 342.21 points;the intercepting and serving blocking rate is 29.73%,the error rate is 10.81%,the blocking and serving Vote value is 262.16 points,and the blocking rate is 13.14%.,the error rate is 37.96%,the blocking Vote value is 145.99 points;the defense in-place rate is 31.07%,the error rate is 25.59%,and the defensive Vote value is 246.48 points.(3)The total number of violations of the Chinese team’s offensive hip-lifting was 5,and the error rate was(P>0.05)compared with each team,and there was no significant difference;There is a significant difference between the error rate and the Canadian team,the Italian team,the Russian team,the Rwanda team and the American team(P<0.05).(4)The RSR ranking of each team’s offensive strength(r=0.608,P>0.05)has no significant correlation with the final match ranking,the defensive strength(r=0.938,P<0.01)and offensive and defensive strength(r=0.881,P<0.01)of each team were significantly correlated with the final match ranking,the Chinese team’s offensive strength and offensive and defensive strength are in the first gear,and the defensive strength is in the second gear.Research conclusions:(1)The Chinese team has the lowest serving error rate,the highest scoring rate on first offense and counter attack,and is in the leading position in RSR ranking of serving,first offense and anti-counterfeiting technology,and the Chinese team has a strong international offensive.strength.(2)The Chinese team has the lowest error rate in receiving and serving,and the highest rate of receiving and defending.Its receiving and defending skills are excellent,but there is a gap between the skills of blocking and blocking compared with the strong European and American teams,and the defensive strength has obvious technical shortcomings.plate.(3)The Chinese team lost the most points by raising their hips,and the Chinese team lost significantly more points than other teams when they blocked the net.(4)There is a significant relationship between the defensive strength,offensive and defensive strength of the sitting volleyball team and the game performance,and a team with a balanced offensive and defensive ability can achieve better results.
