Orignal Paper : Effect of Vibratory Stimulation on Recovery of Muscle function from Delayed Onset Muscle Soreness
Abstract
This study was designed to investigate the effect of vibratory stimulation on recovery of muscle function from delayed onset muscle soreness (DOMS). Volunteers performed 3 set of 70 % maximal voluntary eccentric muscle contraction and induced DOMS. volunteers were allocated to one of three treatment group after DOMS : groupⅠ (control), groupⅡ (ultrasound), groupⅢ (vibration). Maximal Voluntary Isometric Contraction (MVIC), Visual Analog Scale (VAS), Range Of Motion (ROM), Root Mean Square (RMS), Median frequency (MDF), Blood Serum Creatine Kinase (CK), Lactic dehydrogenase (LDH) were recorded at baseline, and 24, 48, 72 hours post-exercise. In MVIC measurement, there was a statistically significant difference in groupⅢ compared to groupⅠ (p < .05). In VAS measurements, there were a statistically significant difference in groupⅡ and Ⅲ compared to groupⅠ (p < .05). In ROM measurement, there was a statistically difference in groupⅡ and Ⅲ compared to group Ⅰ (p < .05). In Muscle Volume with Ultrasonography measurement, there was no statistically significant difference in any groups (p > .05). In RMS and MDF measurement, there were a statistically significant difference in groupⅡ and Ⅲ compared to groupⅠ (p < .05). In Blood samples of CK and LDH measurements, There were no statistically significant difference in any groups (p > .05). From the above result, Vibratory stimulation had a positive effect on recovery of muscle function from delayed onset muscle soreness. Further studies should be undertaken to ascertain the more effectiveness of vibratory stimulation and may be a promising treatment modality.
Key Words: Delayed Onset Muscle Soreness, Maximal Voluntary Isometric Contraction, Root Mean Square, Median frequency, Vibration
