USING WHOLE BODY VIBRATION TO IMPROVE JUMP ABILITY IN YOUNG RECREATIONAL SPORTMEN
Journal Title: CITIUS ALTIUS FORTIUS - JOURNAL OF PHYSICAL EDUCATION AND SPORT - Year 2010, Vol 27, Issue 2
Abstract
The whole body vibrations (WBV) it is nowadays one of the most widely used methods for improving the explosive strength. In this study, 12 subjects participating in recreational physical activity were allocated to a 5 sets of 60 s training, using a frequency of 30 Hz, an amplitude of 2.5 mm. and a isometric position (110 ° bending knees) on a Galileo Fitness ® (Novotech, Germany) platform. The results showed an increase in SJ (+1.76 ± 4.05 cm) and CMJ (+1.10 ± 3.20 cm) in the post-test conducted just after the vibration. The values of the post-test performed 30 minutes after the squat jump remained above the ones of pre-test but just below the ones of the immediate post-test (+0.42 ± 4.43 cm). By contrast the values in the counter movement jump drop below the pre-test ones (-0.12 ± 2.45 cm). Based on these data it seems that when the frequency is not high it is necessary to use a greater amplitude in order to achieve the desired effects. The effect achieved after the vibration is transient, not remaining after 30 minutes.
