Duplicate- plates WBV and Kistler force plate was used in this study. The frequencies of WBV were set at 30-30 and Hz20-40Hz, and the amplitude of WBV was set at 2mm in all training program. All participants were tested by twice counter movement jumps and twice half-squat jumps before and after the training programs in order to investigate the influences of the program. Paired T-test was used to analyze all the data. Significant level set atα=.05. Sixteen elite female volleyball players participated in this study (average age: 20years, average height: 170cm, average weight: 63kg). All the participants were divided into two groups by eight each randomly. The findings showed: (1) 30-30Hz training program significantly improved single CMJ ability after being trained by duplicate- plates WBV (p<.05). (2) However, there is no significant difference in half-squat jump after four weeks training. Keywords: Duplicate- plates WBV, jumping abilities雙平台震動訓練彈跳力Duplicate- plates WBVjumping abilities
