| Introduction: Delayed onset muscle soreness (DOMS), which may occur after eccentric exercise, is due to the sarcoma disruption or excitations–contractions coupling dysfunction after eccentric exercise. This may cause some reduction in sport activities especially among professionals. For this reason, several studies have been designed on preventing and controlling DOMS after eccentric exercise. It has been shown that vibration training (VT) may improve muscle performance and increase force generation of muscles. This study has been designed to find weather VT may improve muscle function and prevent DOMS after eccentric exercise.
Materials and Methods: Fifty healthy non-athletic volunteers were assigned randomly in two experimental, VT (n=25, 12 male and 13 female, age 20.6 1.9) and Non-VT (n=25, 13 male and 12 female, age 20.6 2.1) groups. A vibrator apparatus was used to apply one minute 50 Hz vibration on the left and right quadriceps, hamstring and cuff muscles in VT group, while no vibration was applied in the Non-VT group. Then, both experimental groups walked downhill on a 10 degree declined treadmill at a speed of 4 km per hour. The measurements included the isometric maximum voluntary contraction force of left and right quadriceps muscles, pressure pain threshold (PPT) on the 5, 10 and 15 cm above of patella and also on the middle line of cuff muscles of both lower limbs before and the day after the treadmill walking. In the next day, we also measured the serum levels of creatine kinase (CK), and also the level of DOMS by visual analogue scale.
Results: The results showed reduced MVC force (P=0.006) and reduced PPT (P=0.0001) in the Non-VT group, compared to the VT group. The mean of DOMS and CK levels were significantly lower in the VT group than the Non-VT group (P=0.001).
Conclusion: Comparison the obtained data from both experimental groups indicates that the applying of vibration before eccentric exercise may prevent and control the DOMS effects. More studies should be done to find the stability and effectiveness of the VT method in the athletics. |
