Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study hypothesize that femur exposed to unilateral vibration may affect the rest muscle electrical activity of contralateral hip adductors. Vibration can effectively enhance muscle strength and power. Previous studies have shown that vibration increases muscle electromyographic (EMG) activity. It has been showed that bone has an effect on the increase in muscle EMG activity caused by vibration in healthy young adults in a study. In this study, it was reported that vibrations-induced increases in muscle electrical activity of flexor carpi radialis (FCR) was related to ultradistal radius bone mineral content (BMC) and the FCR H-reflex was suppressed or depressed during vibration. This findings were reported to support the assumption that the bone exposed to cyclic mechanical loading may neuronally regulate muscle activity.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Vibration will be applied the right lower extremity by whole-body vibration (PowerPlate Pro). Cases will stand on vibration plate. WBV will be applied at a frequency of 40 Hz and amplitude of 2 mm for 60 seconds. WBV will be applied one session only.
The rest muscle electrical activity of ipsilateral and contralateral hip adductor muscles at rest will be measured by PowerLab (data acquisition system, ADInstruments, Australia) device.The rest-EMGrms will be measured at before and during vibration. We also evaluate a change in contralateral soleus H reflex during vibration.
Effects of bone on the rest muscle electrical activity will be assessed by hip bone mineral density, bone mineral content and serum sclerostin level. The right hip bone mineral density (BMD) and BMC will be evaluated by bone densitometer (Norland). Plasma sclerostin level will be measured by using Human Sclerostin ELISA kıt before and after vibration.
