Influence of vibration on some of functional markers of delayed onset muscle soreness

Objective of this study was to the effect of vibration on some of functional markers of delayed onset muscle soreness. Methodology: 30 college males with mean age of 21.2, were selected and were divided into two groups randomly. A vibrator was used to apply 50?Hz vibration for 1 min in the VT group, while no vibration was applied in the non?VT group. Then, Both groups performed five sets (10 repetitions per set) of the eccentric contractions , at 85% of one repetition maximum (1- RM). Range of motion at elbow jount Circomference of nondominant elbow and Muscle soreness were recorded before, after, 24, 48, 72, 96 (hr) after eccentric contractions. Statistical Result: The results showed vibration training do show positive effects on Range of motion at elbow joint and Muscle soreness and Circomference of nondominant elbow (p> 0.05).  Discussion: A comparison by experimental groups indicates that VT before eccentric exercise may prevent and control DOMS.  Key words: Eccntric exercise,Delayed onset muscle soreness, Range of motion, vibration training.
