At the current stage, the terms used in describing the performance of a tennis racket are based on the feeling of an experienced tester or a player. However, the optimum racket depends on the physical and technical levels of each user. Accordingly, there are a number of unclear points regarding the relationship between the performance estimated by a player and the physical properties of a tennis racket. This paper investigates the improvement performance relevant to the power of super-light weighted long-body tennis racket, which has some disadvantage with the restitution coefficient and the rebound power coefficient. It searches the optimal weight attachment for improving the rebound power coefficient and the post-impact ball velocity simultaneously with tennis racket available on the market by using a simple FEM analysis. It is based on the FEM with an equivalent ball-strings compound system. The result shows that the rebound power coefficient and the post-impact ball velocity increases simultaneously by attaching mass to the top side of racket head.
