Acute effects of improvement hamstring flexibility by working with whole body vibration
Keywords:
vibration mechanics, flexibility, hamstring, training, acute effectsAbstract
Introduction: mechanical vibrations are a training method that is on rise in these times providing benefits to different body systems. Objectives: the present study seeks to observe the acute effects of a full body program with WBV on vibration plate on the capacity of hamstring flexibility in young adults. methods: 21 subjects from the general population, aged between 25-35 years, participated in this study voluntarily. They were randomly assigned to an experimental group (GE1: N=7 or GE2: N=7) or in a control group (GC: N=7). All were a workout that consisted of 5 series of exercises of 45 seconds on a vibrating platform: the GE1 used F=25 Hz and A=2 mm, the GE2 used F=45 Hz and A=2 mm while the GC conducted exercises on the platform but without WBV. To assess the flexibility of hamstrings the active knee extension test was done before and after the intervention. Results: The acute effects of whole body vibration showed a significant increase in hamstring flexibility being observed in GE1 (+7,41º) and GE2 (+9,57º) greater gains compared to GC (+2,28º; p<0.05). Such results lasted longer in GE1 y GE2 than in subjects who trained without vibration. Conclusions: A short training program with whole body vibration (25/45 Hz; 2 mm) improves hamstrings flexibility in young adults in the general population.References
