The purpose of this paper is to select 7 male athletes and female athletes of high school, and to compare their active potential differences of upper arm muscles according to characteristic of a racket. the results obtained are as follows:
1. In the accumulative distribution rate of racket string tension, 65Ibs is higher in all muscle active potentials except male flexor carpi radialis muscle than 55Ibs or 60Ibs, and this result shows that 65Ibs gives lower efficiency to athletes.
2. In the muscle load rate of racket string tension, 55Ibs shows the lowest active muscle potential and is thought to be better in its efficiency, but 66Ibs shows a little high active potential and is thought not to be good in its efficiency.
