| ABSTRACT
Background and Aim: The aim of this study was to determine the effect of one-session of whole body vibration training on isokinetic strength of rotator cuff and shoulder proprioception
Materials and Methods: 32 students experienced three positions including control (no vibration), push up with straight elbow and push up with semi flexed elbow (two vibration positions) for 2 minutes with 30 minutes interval between positions. After control position, vibration positions were tested on a random basis by means of a power plate device (Freq: 30Hz and Amp: low ). The isokinetic strength of rotator cuff and shoulder proprioception were measured in angle repositioning test in 3 target angles of 0°, 45° and 90° by means of Kin-Com dynamometer before and after each position. Then the results of 3 positions were compared with one another.
Results: Despite decreased dynamic strength of medial rotators after 3 positions, this decrease was significantly less in push up with straight elbow than that in control position (p=0.03). Also there was a significant difference in concentric MPT of lateral rotators between 3 positions so that, control position caused the greatest decline in lateral rotators strength (p=0.01) and push up with straight elbow was more effective than push up with semi flexed elbow (p=0.03). Moreover, There was a significant improvement in angle repositioning in 3 positions but only in zero degree a significant difference was detected between the push up with semi flexed elbow position and the control position (p=0.03). No significant change in muscle strength was found between push up with straight elbow and semi flexed elbow positions.
Conclusions: The results of this experiment show that a two minute single-session of whole body vibration is relatively a good stimulation for neuromuscular system in young and healthy individuals.
