Research On The Construction And Evaluation Of Tennis Specific Agility Structure Model

With the in-depth study of competitive tennis,it is found that the specific agility plays an important role in the development of competitive level of tennis players.In order to further understand the basic structure of tennis specific agility,this research adopts the research methods of literature,expert investigation,testing,mathematical statistics,etc.,and takes 80 tennis major students(gender: male;age: 17-23 years old)of Wuhan Sports University as the test object,establishes the tennis specific agility structure model and the corresponding evaluation standards.The conclusion is as follows:(1)Of this study is to build the tennis specific agility quality structure model by four primary index(the ability to change direction,coordination,transform action and quick reaction capability)and nine secondary index(hexagon jump,cross back to running,spiders,1 minute double wave rope skipping,repeated across,footwork movement across line,burpee,prone to stand up,comprehensive reaction and six corner test)hierarchical structure.(2)Weight distribution of the indicator system is as follows: First-level indicators: A1:A2: A3: A4= 0.45:0.26:0.13:0.16;Secondary indicators: B1: B2: B3= 0.32:0.22:0.46,B4:B5= 0.60:0.40,B6: B7= 0.57:0.43,B8: B9= 0.42:0.58.(3)The tennis agility evaluation standards(single index evaluation and comprehensive evaluation)formulated by this study are convenient for coaches to make reasonable evaluation on the athletic level of college tennis athletes and to monitor the training effect before and after.(4)The tennis specific agility evaluation standard constructed in this study has been proved by the retrograde test to be reasonable,reliable,effective and operable,and meets the requirements of validity,accuracy and applicability of measurement.
