Introduction: Delayed Onset Muscle Soreness (DOMS) is a common strain resulting during therapeutic exercise with eccentric contractions. This pain can result in loss of interest by the patient and eventually in cancellation of the routine. The purpose of the present study was to determine whether vibration could have an affect on delayed onset muscle soreness. We hypothesized that the vibration training would decrease DOMS.
Methods: Subjects comprised of 30 male athletes aged 18-26 years. The athletes were involved in regular sports activities since at least three years. Subjects were assigned randomly into two VT (n=15) and Non-VT (n=15) groups. The measurements included the flexed knee angle (FANG), pressure pain threshold (PPT), muscle soreness (SOR) of right quadriceps muscle and maximal isometric force (MIF) of both quadriceps muscles together (Base-line). A vibrator was used to apply 50 Hz vibration on the left and right quadriceps muscles for 1 min in the VT group. Then both groups trained eccentric exercise. All parameters were determined again 24 hours post-exercise (After- activity).
Results: All subjects showed a loss in MIF, decrease in PPT, FANG and increase in SOR 24h after eccentric exercise (p=0/000). But the parameters were statistically significantly different in the VT and Non-VT groups [MIF (p=0/000), PPT (p=0/001), FANG (p=0/02), SOR (p=0/003)].
Conclusion: Therapeutic exercise with eccentric contractions results in DOMS, but vibration training before exercise is effective and beneficial in decreasing DOMS.
