The application of literature material method, expert interview method, mathematical statistics and comparative analysis method, to Li Na of the 2011 French underground race of 7 games as the research object, Li Na in the competition score winning factors to carry on the research analysis, corresponding Li Na to score the relevant element make regression analysis, found advantages of Li Na in the contest winning score, certainly affect Li race to score an important identity and stop parsing, to improve their singles competition of athletics level. The results of the study are as follows: 1. Serve, Li Na a wins rates with the adversary serves wins rates are obviously abnormal difference, Li Na was significantly better than the opponent; a serve scoring rate, Li Na and between rival exist significant differences between, with a p value of less than 0. 05; Li Na more emphasis on the middle of the serve; two hair score rate, P value of less than 0. 05, Li Na compared to the players there is a significant advantage, with a significant difference; ACE ball and double error, P values are greater than 0. 05, there is no obvious difference between the two sides. 2. Receiving, Li Na and adversary in ace don't rate there was a significant difference between, Li Na after a pay more attention to the service of the solid ground, two enhanced the ball defensive than rival slightly better. 3. Break skills and on both sides in the break point opportunities, break the number of victories and break wins rates stop independent sample t hone obtained P values were less than 0. 05, Li Na in the above three aspects have a significant advantage. 4. Unforced loss error and automatic score (winners) aspects, by independent sample t trials, on both sides of the automatic scoring exist obvious difference, 2011 French Open 7 games, Li than the other above 68 record the winning points, even every 7. 6; there is no obvious difference between the two sides in the non forced out of error. 5. Net technique, through independent sample t hone, on both sides of the net score, sufficient number of scoring rate of P values are larger in 0. 05, explain Li Na in 2011 in the French tennis underground in the network before the skills and the opponent does not exist obvious difference. 6. Through the analysis of all the regression analysis that, Li Na in 2011 in the French Open tennis tournament in the identity of the winning score, other factors are not the most important reason for Li Na's success. 目录: |
