Delayed onset muscle soreness (DOMS), which may occur after eccentric exercise, may cause some reduction in ability in sport activities. Many studies have been done on preventing and controlling DOMS for this reason. Vibration training has been shown to improve muscle performance, so a study was done to investigate the effect of Vibration training on controlling and preventing DOMS after eccentric exercise. Fifty healthy non-athletic volunteers were assigned to two groups, Vibration training and non-vibration training. 50 Hz vibration was applied on the left and right quadriceps, hamstring and calf muscles for 1 min in the VT group, while no vibration was applied in the non-VT group. Then, both groups walked downhill on a 10 degrees declined treadmill at a speed of 4 km/hour.
The results showed decreased Isometric Maximum Voluntary Contraction force, reduced Pressure Pain Threshold, and a significant increase of DOMS and Creatine-Kinase levels in the non-Vibration Training group, compared to the Vibration Training group.
These results indicate that Vibration Training before eccentric exercise may prevent and control delayed onset muscle soreness.
