Acute bouts of whole body vibration (WBV) have been shown to improve muscular strength, vertical jump, and muscular power, but the muscular benefits may not last long enough to have a benefit in most sporting events. However, the rate of play in American football may still allow for performance benefit from WBV. PURPOSE: To evaluate the effect of Whole Body Vibration on the horizontal power output of football lineman. METHODS:12 Willamette University football players were randomized into two groups. Each group received Whole Body Vibration on one of two days after completing a dynamic warm up. Participants then performed a Sled Push Test immediately, five minutes, and ten minutes post warm-up. The Sled Push Test was used to determine power output. A paired T-test was run comparing the vibration vs. non-vibration groups. RESULTS: Power output was greater in the vibration condition by 255 W for the immediate test and 81 W for the test after 10 minutes. However, power output results were 117 W lower in the vibration condition for the test after five minutes. P-values of .76 were determined for the immediate test, .87 for the 5 minute condition and .89 for the 10 minute condition. No results were statistically significant. CONCLUSION: These findings suggest there is no significant benefits of using Whole Body Vibration on football lineman in improving horizontal power output or enhancing performance.
