The purpose of this study was to investigate the effect of mechanical vibration on acute power output in the bench press. A total of 10 male subjects performed 3 sets of 3 reps of bench presses using a load equal to 70% one repetition maximum (1RM) on two occasions separated by 3 days. One occasion served as the experimental (vibration) condition while the other occasion served as the control (non-vibration) condition. The conditions differed due to a 30 second vibration stimulation period between bench press sets 2 and 3 in the experimental condition. The control condition incorporated a 30 second isometric hold with no vibration between bench press sets 2 and 3. Peak and average power output were calculated from the displacement versus time data in the bench press sets to see if differences existed in power performance following the vibration stimulation. The results were compared using a repeated measures ANOVA. Average power but not peak power was significantly higher following vibration stimulation compared to the control condition. Vibration stimulation also allowed for power output to be maintained in the last bench press set compared to the control condition. It was concluded that vibration stimulation may allow for higher levels of power endurance.
