The consequences of treatment involving the use of a natural product and whole body vibration (WBV) exercise have been investigated. The aim of the present study was to evaluate the effects of the joint treatment with an aqueous extract of Chenopodium ambrosioides and WBV on physiological parameters in rats. Wistar rats (n=20) were divided equally into four groups: control group (CG), treated with C. ambrosioides (CHE) group, exposed to 50 Hz of mechanial vibration (VBR), and treated with C. ambrosioides and exposed to 50 Hz of mechanical vibration (VBR + CHE) daily for 6 weeks. The body mass of the animals was determined weekly, the feed intake and the stool consistency were measured daily. One day after the 6 weeks of treatment, samples of blood were collected and used for biochemical analysis. Along 6 weeks, there was an increase (P<0.001) in the feed intake in VBR group and a decrease in the CHE group in comparison with other groups. The levels of the enzyme aspartate aminotransferase (AST) in VBR + CHE group decreased (P<0.05) in comparison with other groups. No differences were found in body mass and stool consistency. WBV altered the feed intake without directly affecting the body mass. Moreover, WBV in association with C. ambrosioides caused alteration in the enzymatic activity of AST.

The aim of the present study was to evaluate the effect of the association of whole body vibration (WBV) exercise with an aqueous extract of coriander on the biodistribution of the radiopharmaceutical sodium pertechnetate, on the concentration of some plasma biomarker, on the feed intake, on the body mass, and on the stool consistency in rats. Rats were divided in four groups and submitted to different treatments for 40 days. The control group (CON) received deionized water. The group treated with coriander (COR) received the extract of coriander. The rats that were exposed to WBV exercises (WBV-E) also received deionized water. A group of animals received coriander and was exposed to WBV (COR + WBV-E). We found in testis a decrease (0.13 ± 0.01 to 0.06 ± 0.03) of the percentages of injected radioactivity per gram (%ATI/g) in the WBV-E in comparison with the COR. There is no significant alteration on the concentrations of the plasma biomarkers. The feed intake showed a statistically significant increase in WBV-E. No significant difference on the body mass was found. The stool analysis showed a statistical difference on the consistency between COR (hard and dry, darker) and all the other groups (normal). In conclusion, it was verified that possible modifications in some biochemical/physiological parameters of the rats submitted to WBV exercise would be capable to increase the feed intake without changing the body mass, and normalizing the stool consistency altered by the coriander supplementation. Further studies are needed to try to understand better the biological effects involving the association of WBV exercise and coriander.

Introduction: Metabolic syndrome (MetS) is characterized bya group of cardiovascular risk factors, such as hypertension,hyperglycemia, hypercholesterolemia, low high-density cholesteroland increased abdominal fat. Over the years, changesin body composition occur, with accelerated loss of lean massand increased fat mass, favoring cardiometabolic disorders.A strong relationship exists between physical inactivity andthe presence of multiple risk factors for MetS. Thus, physicalexercise has been recommended for the prevention of cardiovascular,chronic and MetS diseases. Whole-body vibration(WBV) exercise can be considered to be an exercise modalitythat benefits the muscular strength and cardiovascular healthof elderly, sick and healthy people. Individuals with MetSare unmotivated to perform physical exercise regularly and,therefore, new approaches to intervention for this populationare desirable. Objectives: The aim of this study is to presenta protocol to verify the effect of WBV exercise on the bodycomposition of MetS individuals. Methods: Randomized controlledtrial with MetS individuals that will be allocated to anintervention group (WBVG) and a control group (CG). Participantswill be placed barefoot on the base of a side alternatingvibrating platform, with 130º knee flexion. Individuals (WBVGand CG) will perform the protocol for 12 weeks, twice a week.The CG subjects will perform the exercises at 5Hz throughoutthe intervention and those from the WBVG will perform the5Hz exercises in the first session, adding 1Hz per session, endingthe protocol at 16Hz. The body composition will be evaluatedbefore and after the protocol using bioelectrical impedanceanalysis. Discussion: Studies involving WBV exercise haveshown improvement in composition in individuals withdifferent conditions (healthy and unhealthy). Conclusion: Theproposed protocol will permit the acquisition of findings thatwill be relevant in the evaluation of the effect of the WBV onthe body composition of MetS individuals due to its ease ofrealization, low cost and safety.Keywords: Whole body vibration exercise; Metabolic syndrome;Physical activity.

Urban rail is a widely used public transportation; the vibration from frequent rides may impact passengers. The rail vehicle’s vibrations can cause human fatigue and result in severe musculoskeletal problems to the passenger. This paper aims to identify the effects of passenger orientation, operation time and body mass index on passengers’ whole-body vibration on an urban rail in Malaysia. Real-time monitoring of the whole-body vibration was conducted using 23 full factorial designs of the experiment, which was analysed statistically using Minitab Software. The overall result of this study is that the passengers in a seated position had greater exposure to whole-body vibration, which is 0.3686 ms-2 than standing passengers, 0.2965 ms-2. Also, passengers tend to be exposed to greater vibration during an off-peak time of 0.4063 ms-2, than a peak time of 0.3706 ms-2. Lastly, overweight passengers were exposed to greater vibration, of 0.4063 ms-2, than passengers within the ideal weight range of 0.4000 ms-2. This study has statistically proven that all the factors were significantly influenced the vibration exposure to the passenger. The most significant factor towards the vibration exposure is the “Body Mass Index (BMI)”, in which the p-value is less than 0.001. This study concludes that the whole-body vibration of a passenger is affected by the orientation of the passenger, operation time and body mass index of passengers on urban rail service.

Whole body vibration has been proven to improve the health status of patients with fibromyalgia, providing an activation of the neuromuscular spindles, which are responsible for muscle contraction. The present study aimed to compare the effectiveness of two types of whole body vibrating platforms (vertical and rotational) during a 12-week training program. Sixty fibromyalgia patients (90% were women) were randomly assigned to one of the following groups: group A (n = 20), who performed the vibration training with a vertical platform; group B (n = 20), who did rotational platform training; or a control group C (n = 20), who did not do any training. Sensitivity measures (pressure pain and vibration thresholds), quality of life (Quality of Life Index), motor function tasks (Berg Scale, six-minute walking test, isometric back muscle strength), and static and dynamic balance (Romberg test and gait analysis) were assessed before, immediately after, and three months after the therapy program. Although both types of vibration appeared to have beneficial effects with respect to the control group, the training was more effective with the rotational than with vertical platform in some parameters, such as vibration thresholds (p < 0.001), motor function tasks (p < 0.001), mediolateral sway (p < 0.001), and gait speed (p < 0.05). Nevertheless, improvements disappeared in the follow-up in both types of vibration. Our study points out greater benefits with the use of rotational rather than vertical whole body vibration. The use of the rotational modality is recommended in the standard therapy program for patients with fibromyalgia. Due to the fact that the positive effects of both types of vibration disappeared during the follow-up, continuous or intermittent use is recommended.

Abstract Background Hemiplegic cerebral palsy (CP) enormously affects the quadriceps and hamstring muscles. It causes weakness in the affected lower-extremity muscles in addition to muscle imbalance and inadequate power production, especially in the ankle plantar-flexor and knee extensor muscles. It also causes anomalous delayed myoelectrical action of the medial hamstring. A whole-body vibration (WBV) exercise can diminish muscle spasticity and improve walking speed, muscle strength, and gross motor function without causing unfavorable impacts in adults suffering from CP. Thus, the aim of this study is to investigate the impacts of WBV training associated with conventional physical therapy on the quadriceps and hamstring muscle strength, endurance, and power in children with hemiparetic CP. Results The post-intervention values of the quadriceps and hamstring muscle force, endurance, and power were significantly higher than the pre-intervention values for both groups (p = 0.001). The post-intervention values of the study group were significantly higher than the control group (quadriceps force, p = 0.015; hamstring force, p = 0.030; endurance, p = 0.025; power, p = 0.014). Conclusion The 8 weeks of WBV training that was added to traditional physical therapy was more successful in improving the quadriceps and hamstring muscle strength, endurance, and power in children with hemiparetic CP when compared to traditional physical therapy alone.

Firing Properties

The study aimed at determining the influence of a whole body vibration (WBV) on electrophysiological properties of spinal motoneurons. The WBV training was performed on adult male Wistar rats, 5 days a week, for 5 wk, and each daily session consisted of four 30-s runs of vibration at 50 Hz. Motoneuron properties were investigated intracellularly during experiments on deeply anesthetized animals. The experimental group subjected to the WBV consisted of seven rats, and the control group of nine rats. The WBV treatment induced no significant changes in the passive membrane properties of motoneurons. However, the WBV-evoked adaptations in excitability and firing properties were observed, and they were limited to fast-type motoneurons. A significant decrease in rheobase current and a decrease in the minimum and the maximum currents required to evoke steady-state firing in motoneurons were revealed. These changes resulted in a leftward shift of the frequency-current relationship, combined with an increase in slope of this curve. The functional relevance of the described adaptive changes is the ability of fast motoneurons of rats subjected to the WBV to produce series of action potentials at higher frequencies in a response to the same intensity of activation. Previous studies proved that WBV induces changes in the contractile parameters predominantly of fast motor units (MUs). The data obtained in our experiment shed a new light to possible explanation of these results, suggesting that neuronal factors also play a substantial role in MU adaptation.

Therapeutic Measures

Over the last decade, the use of vibration-supported therapeutic measures has been increased. There are many devices in the market that generate whole body vibration, but they can be divided into three groups due to the frequency, amplitude and direction of the vibrations being applied to the body. The aim of the work is to analyze the results of the most important works discussing the use and effectiveness of the therapeutic effect of vibrations on the human body. The studies are indicative of favourable changes to the symptoms of neurodegenerative diseases, neurological dysfunctions, incomplete spinal cord injury, sarcopenia and senile age disorders, osteoporosis, sports injuries. The use of whole body vibration does not result in significant changes to the hemodynamic function during therapy, although appropriate stimulation parameters may induce sufficient cardiovascular response to improve overall physical fitness. In the physiotherapy procedure, the whole body vibration is another means of increasing the effect of the therapy used.

Reach Movements

Simulation of human movements is an essential component for proactive ergonomic analysis and biomechanical model development (Chaffin, 2001). Most studies on reach kinematics have described human movements in a static environment, however the models derived from these studies cannot be applied to the analysis of human reach movements in vibratory environments such as in-vehicle operations. This study analyzes three-dimensional joint kinematics of the upper extremity in reach movements performed in static and specific vibratory conditions and investigates vibration transmission to shoulder, elbow, and hand along the body path during pointing tasks. Thirteen seated subjects performed reach movements to five target directions distributed in their right hemisphere. The results show similarities in the characteristics of movement patterns and reach trajectories of upper body segments for static and dynamic environments. In addition, vibration transmission through upper body segments is affected by vibration frequency, direction, and location of the target to be reached. Similarities in the pattern of movement trajectories revealed by filtering vibration-induced oscillations indicate that coordination strategy may not be drastically different in static and vibratory environments. This finding may facilitate the development of active biodynamic models to predict human performance and behavior under whole body vibration exposure.

Objective. This study investigated the acute residual effects induced by different frequencies of whole-body vibration (WBV) on postural control of elderly women. Design. Thirty physically active elderly women (67±5 years) were randomly divided into three groups: two experimental groups (high WBV frequency: 45 Hz and 4 mm amplitude, n=10; low WBV frequency: 30 Hz and 4 mm amplitude, n=10) and one control group (n=10), with no treatment. The participants were first subjected to stabilometry tests and were then guided through three sets of isometric partial squats for 60 s while the WBV stimulation was applied. The control group was subjected to the same conditions but without the WBV stimulation. The participants were again subjected to body balance tests immediately following the end of the intervention period and again at 8, 16, and 24 min. To measure body sway control, three 60 s tests were performed at 10 s intervals for each of the following experimental conditions: (1) eyes opened and (2) eyes closed. The following variables were investigated: the average velocity of the displacement of the centre of pressure in the anterior-posterior and medial-lateral planes as well as in the elliptical area. Results. A 3 (condition) × 5 (test) two-way repeated-measures ANOVA did not identify significant differences in the stabilometric variables, regardless of group, time, or experimental condition. Conclusions. The effect of WBV, regardless of the stimulation frequency, did not have a significant effect immediately after or up to 24 minutes after vibration cessation, on the variables involved in the control of postural stability in physically active elderly women.
