The effect of whole body vibration on knee extensors strength, dynamic balance and functional activity of lower limb in athlete and non-athlete Subjects
Objective: The aim of this study is to compare the effect whole body vibration on lower limbs functional activity, knee extensors muscles strength and dynamic balance in the healthy athlete and non-athlete subjects.
Design: This is a non-randomized clinical trial study with no control group.
Setting: 40 healthy students including 20 athletes and 20 non-athlete subjects will participate in this study.
Inclusion and Exclusion: The main inclusion criteria are healthy volunteer athlete and non-athlete students aged between 18-30 years old who will refer to Neuromuscular Rehabilitation Research Center of Semnan University of Medical Sciences. The main exclusion criteria are irregular participation during the training session, any neuromusculoskeletal and cardiopulmonary problems during training session and some problems such as LBP, tumors, migraine, vertigo, DVT, hip, knee and ankle joints deformities and pregnancy.
Intervention: Whole body vibration will be applied 6 sessions (3 times per week) for each participant. The frequency of device is 35 Hz and the amplitude 2 mm. Each session will be included 10 sets of vibration training with 1 min. vibration and 1 min. rest between 2 sets.
Main Outcome Measures: After intervention, vertical jump height, knee extensors muscles torque and dynamic stability indices will be investigated and compared between athlete and non-athlete participants.
