The aim of this study is to determine the effects of Whole Body Vibration on muscle activity and timing of the Upper Extremity muscles in Modified Push Up position. Forty female students will be divided into Whole Body Vibration (WBV) and Control (no vibration) groups. Participants in the WBV group use an experimental vibration protocol of 5 × 30 seconds at 5 mm and 30 Hz, in a modified push up position. Surface EMG will be measured for the Upper Trapezius, Serratus Anterior, Biceps Brachii and Triceps Brachii Before, during and after the vibration. Measurements of Reaction Time (premotor and motor time) will be collected before and after the vibration using a digital electrogoniometer.
