| Objective:To test the method on children aged 8-11 who use the tennis training aid for testing and validation and comparative analysis, draw conclusions and make recommendations.Methods:This article uses the literature to determine experimental program to 68 8-11 year-old tennis learner subjects were randomly divided into experimental group (A group, B group, C group) and control group (D group) 17 people. A group, B group, C group have carried out the first half of the regular class more than the ball hitting the training point:A group of half a period after the first half of the baseball bat batting practice, hitting the latter part of regular soft tennis racket practice. Group B semi-class simulation of the first part of the hand backhand throw the ball solid practice, the latter part of the hands, pull the rubber band experiment simulated backhand; C group, respectively, after half a period baseball bat batting practice, the conventional tennis racket hit playing soft tennis practice, practice hands and throw the medicine ball with both hands to get started backhand action pull rubber band simulation exercises. D group more than the conventional fixed-point shots ball training. Experiment twelve weeks to test tennis training of learners in each group of indicators, derived data, and data were analyzed statistically. Finally, the conclusion by logical analysis and recommendations.Results:1 A group, C group before the experiment after the experiment compared with the sweet stroke significantly improved the accuracy; with the D group, A group, B group and C group after the experiment significantly improved the accuracy of sweet shots, and with the B group, A group and C group increased more significantly.2 A group, B group, C group before the experiment after experiment compared the accuracy of fixed-point shots, hitting the stability of fixed-point index increased significantly; and the D group, experimental group after the A, B group and C group set Click the ball very significantly improve the accuracy of which the most significant increase C group; after the experiment compared with the D group, A group, B group significantly improved the stability of fixed-point shots, C set point significantly increased the stability ball; D Group accuracy of fixed-point shots before and after experiment, the stability of fixed-point shots, hands backhand power increased significantly; B group, C group before and after experiment hands backhand strength increased significantly, but the A group and D group had no significant difference.Conclusion:1 A set of experiments on the 8-11 year-old tennis ball dessert learners improve the accuracy of the most significant experimental program in the three most obvious effect in the secondary, indicating that the accuracy of the dessert hit the best effect on the A group; A set of experiments In the fixed-point shot accuracy and stability ball compared with the D group was significantly increased, but compared with the C group had no significant effect experiment, A group as effective as B, C group effect; A set of experiments in pairs.2 B experiments on tennis learners aged 8-11 to improve the accuracy of sweet shot was not significant in the experimental program in three secondary effect of the most obvious, and the effect of D group significantly increased, indicating that the accuracy of the dessert shots on the B group is not A, two sets of results is good, but better than the effect of group D; B shot experiments in the fixed-point accuracy and stability ball compared with the D group significantly increased, but the experimental group compared with the effect of C not significant, B not C experimental effect experiments.3 dessert hands backhand stroke backhand strength training exercises and hands superimposed training technique to improve hand backhand stroke accuracy of the stability of fixed-point related to teaching and training in the learner's special strength training is necessary and the most effective fast. |
