The Research About How Sensitivity Physical Quality Influence The Tennis Bottom Line Pumping Strike Technology Learning

In order to confirm the advantage and the disadvantage of sensitivity observing in the tennis teaching, which affect the basic skills during the learning and mastering period. This paper do the teaching experimental study to the affection of the physical sensitivity. Expecting to understand effect degree of the tennis bottom line pumping stokes learning through the sensitivity body quality and understand whether the sensitivity and quality level can promote the basic skills of tennis learning. Thus to provide the theory and practice reference for the teaching reform he teaching quality of basic skills of tennis.This paper test the 2-year-students, experimental and contrast class students tennis skills according to the tennis methods and the evaluation standards studied and promoted by the international tennis federation development in the INT international tennis technical grade test techniques of tennis. After consulting with tennis teaching senior teachers'opinions, we choose result in the sports items of 100 meters, 1500meters, barbell squat and horizontal bar pull-up to test the speed, endurance, strength and upper extremity strength before and after the test.This paper analysis deeply the connection between the physical quality and the tennis bottom line pumping strike technology with the correlation analysis and the method of Gray Correlation Degree Analysis.Analysis result shows that not only from the results of the quantitative analysis but from the result of the qualitative analysis. We accept the correlation analysis results. More importantly, quality is the first row calculation results of sensitivity, which laid the foundation of furthering our understanding of the impact in the sensitivity quality on learning tennis bottom line pumping strike.This paper do the different test between and within the group about the physical qualities and tennis bottom line pumping strike technology study results with the method of same group test to the experimental class and contrast class before and after the test.The results of comparison before and after the test show that: before the test, there is no significant difference of the average, after 4 months training, the students'sensitivity average results of class 2 differ significantly. The averagesare 18.27and 17.35 seconds. Comparing with the data before test, the contrast groups'average result increased by 0.84 seconds, the experimental group average results increased by 1.77 seconds. The result of experimental group is faster than the contrast group by 0.93 seconds.The result shows that the sensitivity quality level not only affect the baseline backhand depth and impact the accuracy, but affect the depth and accuracy the forehand ground stroke more deeply, especially on the forehand depth has a great influence.
