| By using the method of literature review,mathematical statistics,topsis and comprehensive index.This paper make longitudinal comparative analysis on offensive and defensive technology statistics, height and age of players in different positions of Chinese team in the 25th-28 th Asian Men’s Basketball Championships, longitudinal comprehensive evaluation on the overall offensive and defensive strength of Chinese team in the 25th-28 th Asian Men’s Basketball Championships,and horizontal comprehensive evaluation on the overall offensive and defensive strength ofthe top eight teams in the 28 th Asian Men’s Basketball Championships.The results show that:In terms of height and age: the average height differences between the Chinese team center, forward, guard position players in the 25th-28 th Asian Men’s Basketball Championships were not significant(P> 0.05);the average age differences between the Chinese team center, forward, guard position players in the 25th-28 th Asian Men’s Basketball Championships were not significant(P> 0.05).In terms of offensive capabilities: longitudinal comparative analysis on the attack technical indicators ofthe Chinese team in the 25th-28 th Asian Men’s Basketball Championships, only a 2-point percentage indicator showed significant difference(P <0.05), where there were significant differences(P <0.05) between the 26 th and the 28 th,27th,25th; the remaining attack indexes such as the score, number of shooting, 3-point shooting, free throws hits, assists, offensive rebounds, turnovers, fouled number were not exist significant differences(P> 0.05), in which the 3-point shooting, there were significant differences(P <0.05) between the 27 th and the 28 th,25th; The 28 thwas the strongest offensive strength game,Ci value above 0.5 in comprehensive offensive index of the Chinese team, the 25 th,26th,27 thwere relatively weak game, however, offensive Ci values were below 0.5. Horizontal comparative analysis on the offensive capability technical indicators ofthe top eight teams in the 28 th Asian Men’s Basketball Championships, the Chinese team was the strongest offensive strength team, followed by the Iran, the South Korea ranked third,the China, Iran, Korea, Philippines team’s offensive Ci values were above 0.5,which were relatively strong offensive strength,the Japan, Lebanon, Qatar, Indian team’s offensive Ci values were less than 0.5,which were relatively weak offensive strength.In terms of defensive ability: longitudinal comparative analysis on the defensive technical indicators ofthe Chinese team in the 25th-28 th Asian Men’s Basketball Championships, steals indicators showed very significant difference(P <0.01), where there were very significant differences(P <0.01) between the 27 th and the 25 th,26th, showed significant differences(P <0.05) between the 28 th and the 25 th,26th;Blocks index was significantly different(P <0.05), of which showed significant differences(P <0.05) between the 27 th and the 25 th,28th;The rest of the defensive metrics such as loss of points, defensive rebounds, fouls indicators were not exist significant differences(P> 0.05), in which the defensive rebound, there were significant differences(P <0.05) between the 27 th and the 26 th,28th.The 25 th,26th,28 thwere relatively strong defensive strength game,their defensive Ci values were above 0.5,however,the 27 thwas the weakest defensive strengthgame, defensive Ci value was less than 0.5.Horizontal comparative analysis on the defensive capability technical indicators ofthe top eight teams in the 28 th Asian Men’s Basketball Championships, the Chinese team was the strongest defensive strength team,followed by the Philippines, the Lebanon ranked third, the China,Philippines, Lebanon, South Korea team’s defense Ci values were above 0.5, which were relatively strong defensive strength, the Iran, India, Japan, Qatar team’s defense Ci value were less than 0.5, which belongs to the defense relatively weak four teams.The combined effects of the offensive and defensive aspects: longitudinal comparative analysis on the comprehensive offensive and defensive ability indexes ofthe Chinese team in the 25th-28 th Asian Men’s Basketball Championships.On the results of the Topsis evaluation, the 26 th was the strongest in offensive and defensive comprehensive strength, followed by the 28 th, the 25 th ranked third, the 27 th was the weakest, the 26 th,the 28 th,the 25 th belong to were relatively strong performance games in comprehensive offensive and defensive effects, their comprehensive offensive and defensive Ci values were above 0.5,respectively were 0.77416,0.75864,0.74489. However,the 27 th was the weakest a game in comprehensive offensive and defensive strength, comprehensive offensive and defensive Ci value was less than 0.5.On the results of the comprehensive index method evaluation, the 28 th was the strongest in offensive and defensive comprehensive effects, followed by the 26 th, the 25 th ranked third, the 27 th was the weakest,where the composite index were 2.488,2.451,2.319, 1.204.It showed a significant correlation between the results of the two methods that longitudinal evaluation on the comprehensive offensive and defensive ability indexes ofthe Chinese team in the 25th-28 th Asian Men’s Basketball Championships,Pearson correlation coefficient was 0.840(P <0.05).Horizontal comparative analysis on the comprehensive offensive and defensive ability indexes ofthe top eight teams in the 28 th Asian Men’s Basketball Championships. On the results of the Topsis evaluation,it showed a significant correlation between Ci values’ s sequence of comprehensive offensive and defensive ability indexes ofthe top eight teams and the final race rankings, Pearson correlation coefficient was 0.714(P <0.05);The Chinese team was the strongest comprehensive offensive and defensive ability,followed by the Korea, the Iran ranked third,the China, South Korea, Iran, the Philippines and Lebanon team’s comprehensive attack and defense Ci values were above 0.5, respectively were 1.00000,0.74741,0.70331,0.68477,0.55610,which belong to the overall offensive and defensive strength of strong, the Japan, Qatar,India team’s comprehensive attack and defense Ci values were less than 0.5, which belong to the overall offensive and defensive strength of weak three teams. On the results of the comprehensive index method evaluation,it showed very significant correlation between index I values’ s sequence of comprehensive offensive and defensive ability indexes ofthe top eight teams and the final race rankings, Pearson correlation coefficient was 0.881(P <0.01);Comprehensive offensive and defensive effects from high to poor followed by order: the China,Iran,Philippines,Korea, Lebanon,Japan,Qatar and India, in which the synthesized index respectively were 3.36,2.95,2.77,2.64,2.18,1.25,0.95,0.94;It showed very significant correlation between the results of the two methods that horizontal evaluation on the comprehensive offensive and defensive ability indexes ofthe top eight teams in the 28 th Asian Men’s Basketball Championships,Pearson correlation coefficient was 0.929(P <0.01).Thus, the Topsis combined with the comprehensive indexmethod in the comprehensive evaluation of offensive and defensive quality of basketball are scientific, reasonable, and evaluation results are objective,comprehensive evaluation on the basketball offensive and defensive capabilities of the multi-index has great value.The results can be objectively reflected that change trend of comprehensive offensive and defensive quality, excellent and inferior degree of offensive and defensive capabilities,also can be used as test the effectiveness of training, to improve the level of training and the offensive and defensive quality. The main conclusions and suggestions of this study conducive to the overall strength of the Chinese men’s basketball sustained and stable development, and to provide a basis of reference for the Chinese men’s basketball team to manage and control, and explore new ideas and methods to revitalize the Chinese men’s basketball team. |
