Construction Of Special Body Quality Measurement And Evaluation Index System For Men’ Tennis Players In Colleges And Universities

As the material basis for the improvement of athletes’ technical and tactical competitive ability,physical quality is one of the decisive factors of tennis athletes’ competitive ability.The main concern of the coaches is how to enhance the training level of physique,whose prediction is scientific formulation of training plans and effective control of the training process.Therefore,diagnosis and evaluation play a role as the scientific basis in the training process,and they could make a contribution to the promotion of training effect,so as to improve athletes’ competitive ability.Adopting the literature material method,expert investigation method,sports measurement,mathematical statistic approach,the present study took physical quality evaluation index system of college male tennis players in group B as research subject,and made an investigation of the physical quality training level of athletes in group B,who have registered for the 21 th National College Students Tennis Tournament,which was held in Zhengzhou University from July,24 th to July 31 st in the year of 2016.The results include.(a)established physical quality evaluation index system of college male tennis players of group B include forehand side throw of solid sphere,stomach plane support,the fan run,the 2400-meter run,sit-and-reach,one minute rope skipping;(b)formulated the single index grade scale and single grade evaluation criterion;(c)established the calculation model of synthesis score: Y=0.11 forehand side throw of solid sphere + 0.11× stomach plane support + 0.22×the fan run + 0.20× the2400-meter run +0.17×sit-and-reach + 0.19×one minute rope skipping,and the comprehensive grade evaluation criteria was also set up;(d)back substitution to comprehensive grade evaluation criteria was achieved by statistic approach and the method of coaches’ experience evaluation,and the back substitution was highly identical with comprehensive grade evaluation criteria,which showed it is scientific and reliable for the establishment of the comprehensive evaluation model and criteria in the present study for physical quality training level of college male tennis players in group B.
