Tsunami Bar® is a South Carolina based company that makes specialized lifting equipment, specifically barbells. Their fiberglass composite barbells are designed such that they are lightweight and able to oscillate or bend when being used. The oscillatory nature of these barbells recruits more muscle fiber as the lifter is forced to control a dynamic moving object rather than a rigid and inflexible traditional barbell, allowing for greater strength gains. Furthermore, the oscillatory nature of the bar allows the athlete to move the bar at maximal speed and create quicker changes of direction against the force of the bar. As a traditional barbell is lowered it must be decelerated prior to being lifted in the concentric direction. With a Tsunami Bar, the oscillations allow the weights to bend in a downward motion while the bar is pressed in an upward motion. Thus, the lifter is able to generate maximal velocity from the bar. With maximal speed comes greater neural activation and greater power development. (1)
A Furman University study tested two groups of lifters with one group using the Tsunami Bar® and the control group using a conventional steel barbell in squatting exercises. Following a 5 week study, the Tsunami Bar® group saw significantly greater improvements in the Margaria-Kalamen stair power test, a commonly used assessment for measuring lower body power outputs. (2)
In addition to greater muscle recruitment and power outputs, strength coaches such as Joe Defranco have used the Tsunami Bar® in lieu of traditional steel barbells for those with joint pain, specifically for overhead pressing movements (3).
In conclusion, if you are an athlete looking to develop greater explosive power, build more muscle, or someone with joint pain who would like to continue lifting without aggravations, the Tsunami Bar® might be worth a try.
