Research Into Prognosis Characteristics of Return of Service by Tennis Players Under Different Blocking Mode
Taking eight professional tennis players and 8 students in the specialized class as subjects,the prognosis characteristics of return of service by tennis players of different levels is explored in different blocking modes by the use of research methods,such as on-site shooting,experiment,consistency test and mathematical statistics.The results show that in different time blocking,the ability of identifying the placement of return of service performed by subjects in the excellent group is significantly higher than that of the general group,and the accuracy of spin determination of return of service performed by subjects in the excellent group is significantly higher than that of the general group,that in different blocking space,the misjudgment rate of the placement of return of service and the spin performed by subjects is as follows:racket blocking> trunk blocking > head blocking.The information of placement and spin performed by subjects is mainly derived from the racket.
