A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : The effect of muscle activity on bone tissue is well documented. However, there is not enough data on effect of bone tissue on muscle activity. The aim of this study was to determine whether bone exposed to cyclic mechanical loading affects muscle electrical activity in healthy adult volunteers. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Fifty-six volunteers were included in this study. Muscle electrical activity was measured on flexor carpi radialis (FCR) muscle at rest and maximal voluntary contraction (MVC) as EMGrms by surface EMG. Rest-EMGrms, MVC-EMGrms and Hreflex of the right FCR were measured before and during vibration. The right distal radius bone mineral content (BMC) and density were measured by DXA. R Re es su ul lt ts s: : Rest-EMGrms significantly increased during vibration in all cases. Regression analysis revealed that ultradistal (UD) radius BMC was an independent predictor for the change in the rest-EMGrms during vibration. This analysis also indicated that UD radius BMC explained only 54.0% of the variance in the rest-EMGrms during vibration. MVC-EMGrms significantly increased during vibration. Regression analysis revealed that UD radius BMC was an independent predictor for the change in the MVC-EMGrms during vibration. This analysis also indicated that UD radius BMC explained only 28.3% of the variance in the MVC-EMGrms during vibration. H-reflex was significantly suppressed or depressed during vibration in all cases. C Co on nc cl lu us si io on n: : The current study suggests that bone exposed to cyclic mechanical loading can affect muscle electrical activity, based on its BMC. K Ke ey y W Wo or rd ds s: : Bone and bones; muscle, skeletal; vibration Ö ÖZ ZE ET T A Am ma aç ç: : Kas aktivitesinin kemik dokusu üzerine etkisi iyi bilinmektedir. Fakat, kemik dokusunun kas aktivitesi üzerine etkisi hakkında yeterli bilgi yoktur. Bu çalışmanın amacı sağlıklı erişkin gönüllülerde, siklik mekanik yüklenmeye maruz kalan kemiğin, kas elektriksel aktivitesi üzerine etkisi olup olmadığını incelemek idi. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Çalışmaya 56 gönüllü dahil edildi. Sağ fleksör karpi radialis (FKR) kasından istirahatte ve maksimal istemli kasılma (MIK) sırasında, yüzeyel EMG ile kas elektriksel aktivitesi EMGrms olarak ölçüldü. Sağ FKR kasında vibrasyondan önce ve vibrasyon sırasında istirahat-EMGrms, MIK-EMGrms ve H-refleksi kaydedildi. Sağ distal radius kemik mineral içeriği (KMI) ve yoğunluğu DXA ile ölçüldü. B Bu ul lg gu ul la ar r: : İstirahat-EMGrms vibrasyon sırasında tüm olgularda anlamlı olarak arttı. Regresyon analizi vibrasyon sırasında istirahat-EMGrms'de meydana gelen değişim için ultradistal (UD) radius KMI'nin bağımsız bir belirteç olduğunu gösterdi. Bu analiz aynı zamanda, UD radius KMI'nin, istirahat-EMGrms'de vibrasyon sırasında meydana gelen değişimin % 54'ünü açıkladığını göstermektedir. MIK-EMGrms vibrasyon sırasında anlamlı olarak arttı. Regresyon analizi, vibrasyon sırasında MIK-...
