“…It was hypothesized that mechanical stimuli are transmitted to sensory receptors of muscles, most likely the spindles, and that receptor activation results in the reflex stimulation of motor units, as seen in the tonic vibration reflex (15). However, the tonic vibration stretch reflex was originally described as the result of a brief exposure to high-frequency stimulation applied directly to a tendon (16,17).…”

“…However, the tonic vibration stretch reflex was originally described as the result of a brief exposure to high-frequency stimulation applied directly to a tendon (16,17). Any activation prolonged for tens of seconds could induce a reduction in muscle spindle firing frequency and, as a consequence, a decrease in muscle activation (15). Moreover, muscle spindle firing induced by vibration excites not only motor neurons but also interneurons in the spinal cord, which reciprocally inhibit the motor neurons of antagonist muscles (18).…”

Abstract. Several studies have examined the effects of vibrations on muscle mass and performance in young healthy people. We studied the effects of vibrations on muscles of elderly male and female volunteers (65-85 years of age) diagnosed with sarcopenia. We applied mechanical vibrations locally (local vibrational training) to the thigh muscles at 300 Hz for a period of 12 weeks, starting with a session of 15 min stimulation once a week and increasing to three sessions of 15 min per week. Treated muscles displayed enhanced maximal isometric strength and increased content of fast MyHC-2X myosin. Single muscle fiber analysis did not show any change in cross-sectional area or in specific tension. Analysis of transcriptional profiles by microarray revealed changes in gene expression after 12 weeks of local vibrational training. In particular, pathways related with energy metabolism, sarcomeric protein balance and oxidative stress response were affected. We conclude that vibration treatment is effective in counteracting the loss of muscular strength associated with sarcopenia and the mode of action of vibration is based on cellular and molecular changes which do not include increase in fiber or muscle size.

“…The notion that WBV exploits the neuromuscular system's ability to respond to disruptions in stability in order to stimulate and enhance muscle strength and performance has been proposed. 2 It does this by provoking an energy transfer within the body by means of vibrations that result in a stretch reflex.…”

A range of exercise modalities is used in the rehabilitation of individuals with chronic lower back pain (CLBP), the most current being whole body vibration (WBV) training. WBV training is a novel neuromuscular mode of exercise that has recently received awareness as both a medium for improving speed-strength performance in elite athletes, but also as an alternative or complementary training modality to existing exercise programmes in most biokinetics practices and health and fitness centres.

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-...
