The Effect of Acute Vibration Training on Delayed Onset Muscle Soreness in Young Non-Athlete Women

Background: delayed onset muscle soreness (doms) is the sensation of stiffness and pain in the muscles that occurs 24-48 hours after unaccustomed or strenuous exercise. objectives: the aim of this study was to examine and compare the effect of vibration training (vt) on delayed onset muscle soreness. materials and methods: twenty healthy non-athletic volunteers (female, age 20-30 years, body mass 23.27 ± 0.82 kg) were randomly assigned to vt (n = 10) and non-vt (n = 10) groups. a vibrator was used to apply 50-30 hz of vibration on the left quadriceps and calf muscles in the vt group, while no vibration was applied for the non-vt group. then, both groups ran downhill on a -5° treadmill at a speed of 5-7.5 km/hour (increasing speed). twenty-four-hours before and after the vibration training, serum creatine kinase levels, pressure pain threshold and the rate of edema were measured. results: compared with the non vt group, the vt group showed a significant decrease in pressure pain threshold at 15 cm of patellar point (p = 0.042) and calf muscle (p = 0.041), there were no significant differences between groups in the pressure pain threshold at 5 cm (p = 0.509) and 10 cm (p = 0.152) points. there was no significant change in the edema rate at the gastrocnemius muscle (p = 0.420) and midpoint of quadriceps muscle (p = 0.380) in vt and non-vt groups. despite the increase in creatine kinase enzymes in the two groups, there was no statistically significant difference between the groups (p = 0.173). conclusions: the results showed that using the vibration training can affect delayed onset muscle soreness (doms) reduction between non-vt and vt groups. further studies with larger samples are needed to determine the vibration training positive and negative effects.
