| With the continuous improvement of the modern competitive volleyball level,the game is becoming more and more intense,which promotes the continuous enrichment and development of offensive tactics.This paper takes the technical and tactical use of the reversal phenomenon in the world women’s volleyball matches as the research object,and selects the 0:2 and 1:2 deficits in the world women’s volleyball matches in the past ten years as the object of analysis.The technical and tactical aspects are analyzed in an attempt to find out the technical and tactical characteristics of the team’s comeback to win when trailing by a large margin.This paper analyzes the technical and tactical use of the reversal phenomenon in the world women’s volleyball matches through literature research method,expert interview method,video observation method and mathematical statistics method.50 matches(250 sets)were observed by video observation method,and independent sample t-test was used to test the differences of the mean values of the data before and after the reversal of the winning team.Finally,the following conclusions were drawn:(一)Among the techniques before and after the reversal,the three techniques of bucketing,defense and blocking had significant differences,and the application effect after the reversal was significantly better than that before the reversal.The three techniques of bucketing,defense and blocking had the best effect in the game after the reversal.(二)Among the attacking tactics after the reversal,the strong attacking tactics were the most effective,and there were significant differences;the attacking points increased after the reversal,and the attacking effect was improved.(三)In the use of tactics before and after the reversal,the adjusted attack in the strong attack had the best effect,the overall effect of the back row attack had less improvement,the overall effect of the back row attack was worse than the overall effect of the strong attack and fast attack,the best effect of the back fly in the fast attack,followed by the back fast,near body fast ball and finally the short flat,the highest success rate of the second pass organization behind the running tactics,and the error rate was significantly reduced.(四)The number of second attack after the reversal is significantly higher than before the reversal,and the effect is better;the effect of probe ball after the reversal is better than before the reversal,and there is a significant difference.the proportion of the use of second attack and probe ball technology in the game after the reversal is significantly increased.(五)In the first attack tactics system after the reversal,the effect of buckling and first pass techniques were better than before the reversal,and the effect of strong attack tactics was the best and significantly better than before the reversal.(六)In the post-reversal defense and counter-attack system,the effect of all techniques was better than before the reversal,the overall tactical organization rate increased,and the effect of strong attack and back-row attack were better than before the reversal.After the reversal,the effect of all techniques and tactics of the defense and counter-attack system were better than that of the first attack system. |
