Comparison between Whole and Local vibration effect on delayed- onset muscle soreness following eccentric exercises: a comparative clinical trial study
Healthy untrained volunteers were randomly assigned to Whole body vibration,Local vibration and control groups.Volunteers performed 6 sets of 10 maximal
isokinetic (606/s) eccentric contractions of the dominant-limb knee extensors on a dynamometer. In the Whole body vibration group, the training was applied using a vibratory platform (35 Hz, 5mm peak to peak) with 100 degree of knee flexion for 60 seconds before eccentric exercise. Local vibration group receive local vibration(50 Hz) on the quadriceps tendon for 5 minutes before eccentric exercise. No vibration is applied in the control group. Muscle soreness, thigh circumference, Maximal voluntary
isometric knee ex tensor strength and pain are recorded at baseline
and at 2 days post exercise.
