This paper presents the method of an optimal approach of the dynamic property of tennis rackets by combining the usage of the multivariate analysis and the neural network. Two approaches are used for the several data sampling about playing tennis. One is the evaluation of the dynamic characteristics of tennis rackets, and the other is the evaluation of sensibility of a player while impacting the ball which are obtained through the questionnaire. The several axes to explain the important factors are found by using SD method. Then, the physical properties are obtained by using correlation analysis. Based upon the results of correlation, the evaluate equations between the effective physical values and the sensory factors are established by using the multiple regression analysis. Furthermore the non-linear relation of sensibility is considered by using the neural network. Thus, the evaluate systems which is constructed by neural network, is closer the practical sensibility compared with the evaluate equations constructed by the multiple regression analysis. As the result, it can be said that the direction of an optimal approach of the dynamic property of tennis rackets is shown in the designing stage.
