“…studies have shown that high-frequency, lowamplitude whole-body vibration (WBV) prevented bone loss and the decrease in bone strength in both animals (rats and mice) [ 15 , 31 , 37 , 47 ] and humans [ 18 , 19 ] . The highfrequency vibration signifi cantly prevented soleus muscle atrophy and improved the biomechanical properties of muscle tendon in animals (rats and mice) [ 26 , 38 , 48 ] and humans [ 43 ] . However, some studies have found that WBV might cause discomfort or be deleterious to the peripheral vasculature of mice [ 30 ] and humans [ 24 ] .…”

We investigated the effects of vibration (35?Hz, 45?Hz and 55?Hz) as countermeasure locally applied to unloading hind limbs on bone, muscle and Achilles tendon. 40 female Sprague Dawley rats were divided into 5 groups (n=8, each): tail-suspension (TS), TS plus 35?Hz/0.3?g vibration (TSV35), TS plus 45?Hz/0.3?g vibration (TSV45), TS plus 55?Hz/0.3?g vibration (TSV55) and control (CON). After 21 days, bone mineral density (BMD) and the microstructure of the femur and tibia were evaluated by ?CT in vivo. The biomechanical properties of the femur and Achilles tendon were determined by a materials testing system. Ash weight of bone, isotonic contraction and wet weight of soleus were also investigated. 35?Hz and 45?Hz localized vibration were able to significantly ameliorate the decrease in trabecular BMD (expressed as the percentage change from TS, TSV35: 48.11%, TSV45: 31.09%), microstructure and ash weight of the femur and tibia induced by TS. Meanwhile, 35?Hz vibration significantly improved the biomechanical properties of the femur (57.24% bending rigidity and 41.66% Young?s modulus vs. TS) and Achilles tendon (45.46% maximum load and 66.67% Young?s modulus vs. TS). Additionally, Young?s modulus of the femur was highly correlated with microstructural parameters. Localized vibration was useful for counteracting microgravity-induced musculoskeletal loss. In general, the efficacy of 35?Hz was better than 45?Hz or 55?Hz in tail-suspended rats.

“…According to Sullivan, Dejulia and Worrell, subjects positioning during stretching exercises can result in distinct demands on the muscles being elongated. Although participants positioning during flexibility tests in previous studies were different to those adopted for the LV application, in the present study, both flexibility tests and LV application were performed in a similar positioning. The objective was to guarantee a greater specificity so that changes caused by vibration stimulus would be detected with higher accuracy.…”

Comparison of four local vibratory stimuli on mechanical and sensorial variables related to muscle‐tendon unit response

It is still unclear what is the optimum local vibration stimulus (LV) configuration to generate a greater range of motion gain (ROM) and how LV affects the mechanical and sensory responses of the skeletal muscles. This study aimed to compare the acute effects of four LV configurations on mechanical and sensorial variables related to the muscle‐tendon unit response to stretching. Ten male volunteers were randomly undertaken to four LV configurations (LV1: 14 Hz and 3 mm, LV2: 24 Hz and 3 mm, LV3: 14 Hz and 6 mm, and LV4: 24 Hz and 6 mm) at the right hamstrings muscles, and one non‐vibration condition (control). Maximum ROM (ROMMAX) and torque (TORMAX), and their respective values at the first sensation of tightness (FSTROM and FSTTOR) during stretching maneuvers were measured with an isokinetic dynamometer. Passive stiffness (PS) was calculated as the slope of torque vs. angle time‐series. Repeated measures ANOVA revealed differences between the post‐test and pre‐test values (delta) for the ROMMAX and FSTROM between each local vibration condition compared with the control group (P < .05), with no differences among them (P > .05). The four LV configurations were equally able to improve the ROMMAX and FSTROM, being the LV4 the one that produced higher ROMMAX in 40% of the participants.

“…Another previous study has shown that there is an inverse linear correlation between the mu rhythm of the sensorimotor cortex and the force used during isometric contraction [16], and it was reported that the motor-evoked potential (MEP) was changed by local vibrations [17]. Others have shown improved muscle performance through vibratory stimulation applied to the limbs [14,18,19]. Thomas Lapole et al [19] have reported an increase in joint flexibility due to repeated vibration applied to an Achilles tendon.…”

Thomas Lapole et al [19] have reported an increase in joint flexibility due to repeated vibration applied to an Achilles tendon. Bruno P. Couto et al [18] have applied repeated vibrations of 8 Hz and 26 Hz to two groups, respectively, and they confirmed that the performance of the lower limb muscles was subsequently improved.…”

Mechanical muscle-tendon vibration affects musculature and the nervous system. As the vibrations used in previous studies were varied, consistently determining the effect of mechanical vibration was challenging. Additionally, only a few studies have applied vibrations to dynamic motion. This study investigated whether the vibration based on the sensorimotor response could affect the stability and function of stair climbing. Electroencephalogram (EEG) signals were recorded from the sensorimotor area, and mu rhythms, dependent on the vibration frequencies, were analyzed. Based on the analysis, the vibratory stimulus conditions were set and applied to the Achilles tendon of the lower limb during stair climbing. Simultaneously, electromyogram (EMG) signals from the gastrocnemius lateralis (GL), gastrocnemius medialis (GM), soleus (SOL), and tibialis anterior (TA) were recorded. Activations and co-activations of the shank muscles were analyzed according to the phases of stair climbing. When vibration was applied, the TA activation decreased in the pull-up (PU) phase, and calf muscle activations increased during the forward continuous (FCN) phase. These changes and their degrees differ significantly between stimulus conditions (p < 0.05). Co-activation changes, which differed significantly with conditions (p < 0.05), appeared mostly in the PU. These results imply that the vibration affects stability and function of stair climbing, suggesting that the vibration characteristics should be considered when they are applied to dynamic movement.
