The focus of this research is to examine the impact of 8 weeks of whole body vibration (WBV) exercise on physical factors by conducting an experiment on 17 male bowling players registered in Korea Bowling As-sociation. Strength of truncus and lower-limb and balance were mea-sured as the physical factors and the impact of WBV exercise on each variable was examined. There was significant increase between groups in flexor-weight ratio of truncus at 60°/sec according to perfor-mance after applying WBV exercise. There was significant difference in groups before bowling event in pre and posttest as well as after bowling event in pre and posttest. There was significant difference of extensor-weight ratio in groups after bowling event in pre and posttest. There was significant increase at 60°/sec in flexor-ratio of both left and right lower-limb strength according to performance after applying WBV exercise. There was significant difference between groups before bowling event in pre and posttest as well as after bowling event in pre and posttest. Extensor-weight ratio showed significant difference be-tween groups only before bowling event in pre and posttest. There was significant difference between groups in both left and right balance ac-cording to performance after applying WBV exercise. There was signif-icant difference in before bowling event in pre and posttest as well as after bowling event in pre and posttest.
