Blood flow restriction increases myoelectric activity and metabolic accumulation during whole-body vibration.

Whole-body vibration (WBV) training is frequently applied in sports and rehabilitation with the aim of inducing beneficial functional and structural adaptations. In the past decades, blood flow restriction (BFR) training has received increasing attention by enhancing the effectiveness of several low-load exercise regimens. The objective of this study was to evaluate the additional effect of BFR on myoelectric activity and metabolic accumulation during WBV training. Fifteen active men performed three sessions in a counterbalanced order on three different days: whole-body vibration exercise (WBV), whole-body vibration exercise with blood flow restriction (WBV + BFR), and a control session (CON) with neither WBV nor BFR. Electromyographic (EMG) activity was measured in six lower limb muscles throughout each exercise session; lactate and reactive oxygen species (ROS) concentrations were determined prior to, immediately after and 15min after the exercise sessions. EMG amplitudes increased from CON (29 ± 13% MVC) to WBV (45 ± 20% MVC) to WBV + BFR (71 ± 37% MVC) conditions (p < 0.05). Likewise, lactate concentrations increased in a similar manner, demonstrating significantly higher increases in the WBV + BFR session compared to WBV and CON. Furthermore, significant correlations between lactate concentration and EMG amplitude were detected. ROS concentration did not change significantly between the conditions. The findings of the present study emphasize that the addition of BFR increases the acute effects beyond WBV treatment alone which becomes manifested in both neuromuscular and metabolic adaptations. Further research is needed to identify potential long-term effects of the combination of these two training regimens.

Whole Body Vibration Elicits Differential Immune Responses Between Obese and Normal Weight Individuals

Traditional aerobic exercise decreases the risk of developing inflammatory diseases in both obese and normal weight individuals. The magnitude of the anti‐inflammatory immune response following traditional exercise is reduced and the time‐course is shorter in obese compared to normal weight individuals. Although obesity may affect the ability to engage in traditional exercise, whole body vibration (WBV) has emerged as a more tolerated alternative. The impact of WBV on immune‐mediated inflammation in obesity, however, is unknown.PURPOSETo determine if WBV elicits a differential magnitude and time‐course of immune‐mediated inflammation between obese and normal weight individuals.METHODS11 obese (OB) (BMI: 35.9 ± 8.8 kg/m2, Age: 33 ± 4 y, percent body fat (%BF): 39.1 ± 2.4%) and 12 normal weight (NW) (BMI: 21.3 ± 2.2 kg/m2, Age: 29 ± 7 y, %BF: 17.4 ± 2.1%) men and women participated in this study. Following IV insertion and a resting (PRE) blood draw, each participant performed the WBV protocol, which consisted of 10 cycles of 1 minute of WBV in a static squat position followed by 30 seconds of rest. Following completion of the WBV protocol, blood samples were obtained immediately (POST), 1 hour (1h), 3 hours (3h), and 24 hours (24h) post‐WBV. Blood was analyzed for leukocyte composition (immune‐mediated inflammation) and IL‐6 (muscle activation).RESULTSPRE leukocyte composition was not different between groups. In NW, the percentage of neutrophils decreased (1h: 62 ± 3% vs. 24h: 54 ± 3%, p=0.009) and the percentage of lymphocytes increased (1h: 28 ± 3% vs. 24h: 35 ± 2%, p=0.011). In contrast, there were no changes in leukocyte composition in OB. An association was observed between %BF and the percentage of monocytes at POST (r= −0.67, p=0.023) and 1h (r= −0.65, p=0.03) in OB, whereas in NW %BF was only correlated with percentage of monocytes at PRE (r= −0.61, p=0.045). Although IL‐6 was higher in OB compared with NW at each time point (all p&lt;0.05), a similar percent change from baseline was observed between groups for all post‐WBV time points. IL‐6 at PRE was correlated with percent change at 3h (r= −0.61, p=0.048) only in OB.CONCLUSIONWBV elicited favorable alterations in leukocyte composition over time in NW, while no change in leukocytes were detected in OB. In addition, adiposity appears to impact the timing of the leukocyte response to WBV. Although WBV provoked similar IL‐6 changes in both groups, higher concentrations of IL‐6 at PRE appeared to be related to smaller changes at 3h in OB. Taken together, these data suggest a differential inflammatory immune response to WBV exercise between obese and normal weight individuals.Support or Funding InformationSupported by Medical College of Georgia TUPP awardThis abstract is from the Experimental Biology 2019 Meeting.

Tai Chi and whole-body vibrating therapy in sarcopenic men in advanced old age: a clinical randomized controlled trial.

This study was to investigate the effects of Tai Chi (TC) and whole-body vibration (WBV) exercise in sarcopenic men in advanced old age. Ninety sarcopenic men (mean age 88.6years; age range 85-101years) were divided into three groups: TC group, WBV group, and control (CON) group. Patients in the two treatment groups received 8weeks of training in either TC or WBV, while the control group received reminders not to change their level of physical exercise or lifestyle. Patients in all groups also received health information related to sarcopenia. Muscle mass, muscle strength, and physical performance [balance, gait speed, timed-up-and-go test (TUGT), and five-times-sit-to-stand test (FTSST)] were analyzed and compared among the three groups. Finally, seventy-nine subjects completed the study (TC n = 24; WBV n = 28; and CON 27). Muscle strength was significantly increased in the TC and WBV groups compared to the control group (P < 0.01). Following 8weeks of exercise, improvements were observed in all physical performance tests for the TC and WBV groups (P < 0.05). The improvement in balance was greater in the TC group than the WBV group. Time × Group effects revealed significant improvements in muscle strength in the lower extremities (P < 0.05) and physical performance (P < 0.01) in both the TC and WBV groups. Changes in muscle mass, as measured by dual-energy X-ray absorptiometry, did not significantly differ between groups. These findings indicate that TC and WBV are effective treatments for improving muscle strength and physical performance in sarcopenic men in advanced old age.

Effects of whole-body vibration exercise on functions required for bowling performance of male bowling player.

The focus of this research is to examine the impact of 8 weeks of whole body vibration (WBV) exercise on physical factors by conducting an experiment on 17 male bowling players registered in Korea Bowling Association. Strength of truncus and lower-limb and balance were mea-sured as the physical factors and the impact of WBV exercise on each variable was examined. There was significant increase between groups in flexor-weight ratio of truncus at 60°/sec according to performance after applying WBV exercise. There was significant difference in groups before bowling event in pre and posttest as well as after bowling event in pre and posttest. There was significant difference of extensor-weight ratio in groups after bowling event in pre and posttest. There was significant increase at 60°/sec in flexor-ratio of both left and right lower-limb strength according to performance after applying WBV exercise. There was significant difference between groups before bowling event in pre and posttest as well as after bowling event in pre and posttest. Extensor-weight ratio showed significant difference between groups only before bowling event in pre and posttest. There was significant difference between groups in both left and right balance according to performance after applying WBV exercise. There was significant difference in before bowling event in pre and posttest as well as after bowling event in pre and posttest.

Effect of 12-Week Whole-Body Vibration Exercise on Lumbopelvic Proprioception and Pain Control in Young Adults with Nonspecific Low Back Pain.

BackgroundNonspecific low back pain (NSLBP) accounts for a large proportion of low back pain cases. The present study aimed to investigate the effect of the whole-body vibration (WBV) exercise on lumbar proprioception in NSLBP patients. It was hypothesized that WBV exercise enhances lumbar proprioception.Material/MethodsForty-two patients with NSLBP performed an exercise program 3 times a week for a total of 12 weeks of WBV. The lumbar proprioception was measured by joint position sense. Outcomes were lumbar angle deviation and visual analogue scale (VAS) score.ResultsAfter the 12-week WBV exercise, lumbar flexion angle deviation was reduced from 3.65±2.26° to 1.90±1.07° (P=0.0001), and extension angle deviation was reduced from 3.06±1.85° to 1.61±0.75° (P=0.0001), significantly lower than baseline. After participating in the 12-week WBV exercise, a significant pain reduction was observed (P=0.0001). Men in the whole group (n=32) indicated significantly lower angle deviations in flexion and extension, whereas women (n=10) indicated significantly lower flexion angle deviation (P=0.037), and no significant difference was found in extension angle deviation (P=0.052). However, by subdividing the entire group (n=42) into poor and good proprioceptive groups, WBV exercise presented significant enhancement of lumbar proprioceptive ability in the poor flexion proprioception subgroup, poor extension proprioception subgroup, and good extension proprioception subgroup (each P=0.0001), but not in the subgroup with good flexion proprioceptive ability (P=0.165).ConclusionsLumbar flexion and extension proprioception as measured by joint position sense was significantly enhanced and pain was significantly reduced after 12-week WBV exercise in NSLBP patients. However, the patients with good flexion proprioceptive ability had limited proprioceptive enhancement.

Effects of whole body Vibration exercise combined with Forced weight bearing on balance and gait in patients with Stroke Hemiplegia

Background/Objectives: Forced weight support and whole-body vibration exercise are being widely used in patients with stroke to improve balance and gait. Thirty patients with stroke participated in the experiment. Methods/Statistical analysis: A 10-mm insole underneath the non-affected lower foot and Galileo equipment were used in the experimental group. Only a 10-mm insole was provided underneath the shoe in the control group, and all activities of daily living were performed without the whole-body vibration exercise. The Berg balance scale (BBS), Timed up & go (TUG), and bio rescue balance tests before and after intervention were conducted in all subjects. Statistical analysis was performed using the SPSS version 22.0. Findings: There were statistically significant differences in the BBS test result, limit of stability (LOS), and 10 compared to comparator controls. However, there was no statistically significant difference in the TUG test result and foot print (FP). The experimental group displayed statistically significant differences between the BBS, TUG, FP, LOS, and 10mWT items in the before- and after-intervention comparisons. On the contrary, the control group displayed statistically significant differences in the BBS, TUG, FP, and 10mWT items; however, there was no statistically significant difference in the LOS. Improvements/Applications: In balance and gait, the forced weight support and whole-body vibration exercise yielded symmetrical body weight support and improved the walking speed of the patients with stroke.

Does whole body vibration exercise improve oxidative stress markers in women with fibromyalgia?

The objective of this study was to investigate the effect of whole body vibration (WBV) exercise on oxidative stress markers in a group of women with fibromyalgia (FM) compared to a group of healthy women (CT). Twenty-one women diagnosed with FM and 21 age- and weight-matched healthy women were enrolled the study. Plasma oxidative stress markers (primary outcomes) were evaluated at rest and after WBV, and included thiobarbituric acid reactive substances (TBARS), iron reduction capacity (FRAP), superoxide dismutase antioxidant enzymes activity (SOD), and catalase (CAT). At rest, the FM group had higher TBARS (P<0.001) and FRAP (P<0.001), and lower CAT (P=0.005) compared to the CT. In the CT group, the WBV had no effect on TBARS (P=0.559) and FRAP (P=0.926), whereas it increased both SOD (P<0.001) and CAT (P<0.001). In the FM group, the WBV reduced TBARS (p <0.001), FRAP (P<0.001), and CAT (P=0.005), while it increased SOD (P=0.019). There was an interaction effect (moments vs groups) in the TBARS (effect size=1.34), FRAP (effect size=0.93), CAT (effect size=1.45), and SOD (effect size=1.44) (P<0.001). A single trial of WBV exercise improved all oxidant and antioxidant parameters towards a greater adaptation to the stress response in FM women.

Transmission of Acceleration From a Synchronous Vibration Exercise Platform to the Head During Dynamic Squats.

Many research studies have evaluated the effects of whole-body vibration exercise on muscular strength, standing balance, and bone density, but relatively few reports have evaluated safety issues for vibration exercises. Knee flexion reduces acceleration transmission to the head during static exercise. However, few studies have evaluated dynamic exercises. The purpose of this investigation was to evaluate the transmission of acceleration to the head during dynamic squats. Twelve participants performed dynamic squats (0°-40° of knee flexion) on a synchronous vertical whole-body vibration platform. Platform frequencies from 20 to 50 Hz were tested at a peak-to-peak nominal displacement setting of 1 mm. Transmissibilities from the platform to head varied depending on platform frequency and knee flexion angle. We observed amplification during 20 and 25 Hz platform vibration when knee flexion was <20°. Vibration from exercise platforms can be amplified as it is transmitted through the body to the head during dynamic squats. Similarly, this vibration energy contributes to observed injuries such as retinal detachment. It is recommended that knee flexion angles of at least 20° and vibration frequencies above 30 Hz are used when performing dynamic squat exercises with whole-body vibration.

The short-term health promotion effect of the whole-body vibration exercise program for the improvement of the agility, the quick reaction ability, and the flexibility of the students aspiring for the physical education-affiliated departments in Korea.

The present study aimed to comparatively analyze the effects of the whole-body vibration exercise health promotion program on the agility, the quick reaction ability, and the flexibility of the test-takers. Total 30 test-takers had been prepared for the practical test as the subjects. They were divided into the three groups: the practical college entrance examination group with whole-body vibration exercise, the practical college entrance examination group, and the control group. The measurements of each item were made before and after the program applications of the side steps, the standing long jump, the standing high jump, the sitting trunk flexion, and the trunk forward flexion for 60 min 3 times a week. The side steps showed the significant differences among the groups. Although the standing long jump did not show any significant differences among the groups, the standing high jump showed the significant differences among the groups. Although the sitting trunk flexion showed the significant differences among the groups, the trunk forward flexion did not show any significant differences among the groups. But, the practical college entrance examination program group which carried out the whole-body vibration exercise at the same time showed the highest average value compared to the other groups. It was proven that, to the test-takers who had been preparing for the preparing examination for applying to a physical education-affiliated department, the whole-body vibration exercise program is helpful to the promotion of the health, including the agility, the quick reaction ability, the flexibility, etc.

Cardiorespiratory responses in different types of squats and frequencies of whole body vibration in patients with chronic obstructive pulmonary disease.

This study aims to investigate the cardiorespiratory responses to different vibration frequencies to characterize the intensity of exercise, as well as to compare the effect of two types of squatting exercises (static and dynamic) on the whole body vibration (WBV) exercise in individuals with chronic obstructive pulmonary disease (COPD). Twenty-six subjects were divided and paired into healthy and COPD groups that performed static squatting associated with WBV (frequencies: 30, 35, and 40 Hz; amplitude: 2 mm) and dynamic squatting associated with WBV (frequency: 35 Hz; amplitude 2 mm) on a vertical vibration platform. Oxygen consumption (V̇o2), heart rate (HR), minute ventilation (V̇e), ratio of minute ventilation to oxygen production (V̇e/V̇o2), ratio of minute ventilation to carbon dioxide production (V̇e/V̇co2), oxygen saturation (SpO2), and rating of perceived exertion were measured. For both groups, there was a decrease in V̇e/V̇o2 and V̇e/V̇co2 ratios during static and dynamic squats, as well as an increase in other cardiorespiratory parameters, and no significant difference existed between them. There was an effect of the type of squat on the HR variation; the values in the static squat were higher than those of the dynamic squat in both groups. There was a significant difference with a reduction in SpO2 at 40 Hz frequency when compared with 30 Hz in the COPD group. The other variables behaved similarly between the frequencies. The WBV exercise, regardless of the frequencies used, represented a mild effort that promoted cardiorespiratory response in COPD, with greater responses in the static squat and no adverse effect. NEW & NOTEWORTHY This study showed that an acute session of light exercise of whole body vibration (WBV) can increase the cardiorespiratory responses in patients with chronic obstructive pulmonary disease (COPD), reaching values similar to that of the control group. The results might contribute, therefore, to the elaboration of exercise protocols with WBV for the treatment of patients with COPD during rehabilitation. Thus, future studies referring to training on the vibratory platform could use these exercise parameters and demonstrate possible long-term benefits.

Effects of whole body vibration exercises on functional parameters of individuals with chronic obstructive pulmonary disease

Introduction: Chronic obstructive pulmonary disease (COPD) is a chronic disease related to various systemic manifestations including dyspnea, exercise intolerance and peripheral muscular dysfunction, with a direct impact on functional capacity. Objectives: To verify if whole body vibration exercises (WBVE) can be used as exercise modality in individuals with COPD without leading to exacerbation of the disease, with several clinical benefits. Methods: Individuals diagnosed with COPD, aged ≥ 40 years, will be randomly distributed into 4 groups: control group (CG) who will not undergo WBVE, with their normal daily routine, group who will be exposed to WBVE in the sitting position in an auxiliary chair once a week (GS1) and twice a week (GS2) and WBVE group twice a week in the standing position with knee flexion (GP2). The protocol will last 6 weeks, each session will have 5 sets of 1 min vibration with 1 min rest, frequency 25 Hz and peak-to-peak displacement 2.5 mm. Muscle strength and function will be assessed through manual dynamometry and surface electromyography and dyspnea using the Modified Borg Scale (MBS) and the Medical Research Council (MRC) Scale. Discussion: WBVE, due to the various effects already described, seem to be a promising exercise modality for individuals with COPD, potentially being used as an instrument for pulmonary rehabilitation. Conclusions: The results of this study may provide evidence to justify a WBVE program to the improvement on the physical performance and on neuromuscular function of individuals with COPD.Keywords: COPD; Whole-body vibration exercise; Muscular function; Pulmonary rehabilitation.

Acute Effects of Whole-Body Vibration on the Pain Level, Flexibility, and Cardiovascular Responses in Individuals With Metabolic Syndrome.

The aim of the study was to assess the acute effect of whole-body vibration (WBV) exercise, with low frequency (5 Hz), on the pain level (PL), trunk flexibility, and cardiovascular responses (blood pressure [BP] and heart rate [HR]) in individuals with metabolic syndrome (MetS). Forty-four individuals were included in the study (control: 15) or in (WBV exercise: 29) groups. They were submitted to 3 bouts (1 minute each) of WBV exercise (5 Hz and peak-to-peak displacements of 2.5, 5.0, and 7.5 mm, corresponding to peak accelerations of 0.12, 0.25, and 0.35 g, respectively, sitting in a chair with the feet on the platform with knees flexed, followed by 1 minute of interset rest. The Control Group performed the same protocol, but the platform was turned off. The PL was measured through the visual analog pain scale, and the flexibility was measured through the anterior trunk flexion test. Significant improvements on PL (P = .031) and flexibility (P = .004) were found only in the WBV exercise group. The BP and HR remained at physiological levels. In conclusion, the WBV exercise would lead to physiological response decreasing PL and increasing flexibility as well as maintaining the cardiovascular responses in individuals with MetS.

Relevance of Whole-Body Vibration Exercises on Muscle Strength/Power and Bone of Elderly Individuals

Beneficial effects are associated with whole-body vibration exercises (WBVEs). Increases in muscular strength/power, flexibility, and gait speed; improvements in bone mineral density, balance, and the quality of life; and decreased pain and risk of falls are reported. The aim is to present a review about the importance of WBVE for elderly individuals, considering clinical studies and meta-analyses, on bone and muscle strength/power. There is evidence supporting beneficial effect of WBVE in postmenopausal women (PW); however, effects in PW with osteoporosis are unclear. Age-related decrease in muscle mass and function contribute to undesirable health conditions, including death risk. The WBVEs improve muscle strength/power, functional independence measure, balance, and various fall risk factors, and mobility, measured by Timed Up and Go test, increased significantly after WBVE. An explanation for the absence of positive effects in some outcomes could be related to discrepancies in WBVE protocols as well as the populations tested. It is concluded that WBVE is effective for counteracting the loss of muscle strength associated with sarcopenia in elderly individuals. Balance and leg and plantar flexor strength improvements due to WBV indicate benefit to reduce risk and incidence of falls, frailty, and fracture risks. However, long-term feasibility of WBVE for musculoskeletal and bone health in elderly individuals needs further investigation.

Can Whole-Body Vibration Exercises in Different Positions Change Muscular Activity of Upper Limbs? A Randomized Trial.

The aim of this study was to investigate the acute effects of whole-body vibration exercises (WBVE) in different positions on muscular activity of flexor digitorum superficialis (FD), wrist extensor (ED), and handgrip strength (HG) of healthy men. Fifteen participants have performed 5 test sets each one consisting of HG strength measurement and 1-minute WBVE intervention (frequency: 50 Hz, amplitude: 1.53 mm, synchronous tri-planar oscillating/vibratory platform), that could be control (no exposition to vibration), squat (30 seconds of rest and 30 seconds of WBVE in squat position), or push-up (30 seconds of rest, and 30 seconds of WBVE in push-up position). After testing, participants had 2 minutes of rest and then were encouraged to keep themselves on a pull-up bar for 30 seconds. During all procedures, muscular activity of FD and ED was measured by surface electromyography (EMG). Statistical analysis has revealed that the EMG measured in the FD during the static pull-up bar exercise after SQUAT condition was significantly higher (P = .004) than the CONTROL and PUSH-UP conditions. Whole-body vibration exercises in squat position increase acutely muscle activation of the FD during isometric exercises of longer duration, while muscle activation of ED and HG strength are not affected by WBVE.

Clinical Approaches of Whole-Body Vibration Exercises in Individuals with Stroke: A Narrative Revision.

Stroke is associated with long-term disability and patients experience numerous physical impairments including muscle weakness, particularly in the paretic limbs, balance, and functional mobility. During acute stroke rehabilitation, when individuals are less likely to be functionally independent and rely on rehabilitative care, the efficacy of low skill interventions that can reduce sedentary behaviour should be established. As such, this narrative revision focused on the use of empirical studies of whole-body vibration exercise (WBVE) on different health outcomes in stroke patients. The effects of WBVE on neuromuscular performance (muscular strength and power), mobility, spasticity, and cardiovascular responses have been highlighted. Although some positive results were reported we can conclude that there is no solid evidence confirming the beneficial effects of WBVE among people with stroke compared with either other types of physical activities or sham WBVE. Therefore, further research should be performed in this area, testing the feasibility and efficacy of using WBVE in a more homogeneous sample of stroke patients or comparing different WBVE parameters.

Stochastic Resonance Training Improves Balance and Musculoskeletal Well-Being in Office Workers: A Controlled Preventive Intervention Study

Sixty-two office workers in a Swiss federal department were randomly assigned to a training and a control group. While the training group was instructed to complete 3 stochastic resonance whole-body vibration (SR-WBV) exercises every week for 4 weeks, the control group received no treatment. During this time all participants answered a daily questionnaire concerning their surefootedness, sense of balance, musculoskeletal well-being, and muscle relaxation. Before and after the 4-week SR-WBV intervention, balance was tested with a single-leg stance on a foam mat of the Balance Error Scoring System (BESS) using a SwayStar™-System measuring Total Angle Area (TotAngArea) and Total Velocity Area (TotVelArea). Multilevel results highlighted a significant increase over time for surefootedness and sense of balance (t = 2.491, p = .016), as well as for musculoskeletal well-being and muscle relaxation (t = 2.538, p = .014) in the training group but not in the control group. Balance tests showed improvement of balance in the training group (TotAngArea: Z = 2.550, p = .011; TotVelArea: Z = 3.334, p = .001) but not in the control group. SR-WBV exercise indicated a high compliance during this study (3.87±0.45 trainings per week) underlining its benefits for the working context. Especially office workers who spend most of their time in sitting position could profit from SR-WBV exercise to improve balance and reduce the risk of falls.

Whole-body vibration exercise for low back pain: A meta-analysis protocol of randomized controlled trial.

Low back pain (LBP) affects about 80% of the population at some time in their lives. Exercise therapy is the most widely used nonsurgical intervention for low back pain in practice. Thus, whole-body vibration (WBV) exercise is becoming increasingly popular in relieving musculoskeletal pain and in improving function. However, the efficacy of WBV exercise is not without dispute for low back pain. This meta-analysis, with its comprehensive and rigorous methodology, will provide better insight into this problem. Published articles will be identified using electronic searches from 1950 to 2018. The Cochrane Library, PubMed, Web of Science, Embase, CINAHL-Ebsco, PEDro, and China Biology Medicine will be searched for randomized controlled trials. Studies without a parallel comparison group will be excluded. Two reviewers will independently select relevant studies that investigate on WBV exercise for patients with LBP. Data extraction will be done independently by the same 2 reviewers who selected the studies. The primary outcome will be to assess pain, back-specific disability index, and adverse effect. Continuous data will be pooled by calculating the mean difference using the random-effects model. The results of the final meta-analysis will provide an evidence of WBV exercise for low back pain. This meta-analysis will provide a detailed summary of the evidence on the effects of WBV exercise on patients with LBP, in comparison with general exercise or without treatment. This review will benefit to researchers and policy makers who are interested in the treatment of LBP by WBV exercise.

Whole body vibration exercise in the management of cancer therapy-related morbidities: A systematic review.

The purpose of this systematic review was to investigate the effects of whole body vibration (WBV) exercise in the management of cancer therapy-related morbidities. The PubMED and PEDro databases were used to access publications published in English about the use of whole body vibration (WBV) exercises in cancer patients until February 22nd 2017. The studies included were classified according to the level of evidence (LE) by the National Health and Medical Research Council Hierarchy of evidence and the methodological quality (MQ) by the PEDro scale. The four included studies (2 of them with "high" LE-II and MQ) were performed in patients with different types of cancer (i.e. breast, lung, prostate, solid or hematological), treated with WBV exercise to counteract the cancer therapy-related morbidities. The variables evaluated were muscle activity, subjective rate of perceived exertion, exercise capacity, muscle strength, quality of life, resting urinary incontinence and severity of peripheral neuropathy. Although WBV exercise appears to be a potential treatment procedure of cancer therapy-related morbidities, further additional studies are required to determine specific and tailored protocols to be used in the different stages of the disease.

Effects of whole body vibration exercise on the gait time of individuals with metabolic syndrome: A pseudo randomized controlled clinical study

Individuals with metabolic syndrome (MetS) might present low muscle performance resulting in a decrease of the functional capacity interfering in the gait time. Whole body vibration exercise (WBVe) has been considered in the management of MetS individuals promoting a better functional performance. The aim of this study was to evaluate the effects of WBVe on the gait time of the MetS individuals. CAAE 19826413.8.0000.5259. UTN: U1111-1181-1177; Brazilian Registry of Clinical Trials- ReBEC RBR - 2bghmh. A pseudo randomized controlled trial study with thirty-nine individuals with MetS (according International Diabetes Federation) was performed. The side-to-side alternating oscillating/vibratory platform was used. The individuals were allocated in WBVe group (WBVeG = 22) and in control group (CG = 17). The WBVeG was in squat static position for 1 minute of intervention and 1 minute of rest in 3 different peak-to-peak displacements (2.5, 5.0 and 7.5 mm) 3 times. In the first session was used 5 Hz and increasing 1 Hz in each session up to 14 Hz in the tenth session. In the CG was used the same position and time but the platform was turned off. Before the first and after the tenth session were collected the data about the gait time of 3 meters (in seconds). The statistical analysis was performed using the Graph Pad Prism 5.01 Program ( P ≤0.05). The gait time (Mean ± SD) showed a significant difference intergroups. WBVe is a modality of physical activity that can improve the functional capacity of the MetS individuals, at least, considering the time of the gait.

Assessment Through the Short Physical Performance Battery of the Functionality in Individuals With Metabolic Syndrome Exposed to Whole-Body Vibration Exercises.

Physical activity is recommended in the management of individuals with metabolic syndrome (MetS), and recent studies have suggested whole-body vibration exercise (WBVe) for this population. The aim of this study was to evaluate the functionality through the Short Physical Performance Battery (SPPB) in individuals with MetS after WBVe. The SPPB evaluates the balance, the gait speed, and the lower limb strength (five-chair stand [5CS] test). Forty-four individuals with MetS were divided into WBVe (WBVeG) and control (CG) groups. The individuals of the WBVeG performed 10 sessions of WBVe in an oscillating/vibratory platform (OVP), barefoot, for 3 minutes at the peak-to-peak displacements of 2.5, 5.0, and 7.5 mm, with a resting period of 1 minute (total time: 18 minutes/session). The frequencies ranged from 5 up to 14 Hz. The individuals of the CG performed all the steps of the study, but the OVP was turned off. Before the first and after the tenth session, the individuals performed the SPPB. Significant responses were found in the WBVeG, analyzing the total score of the SPPB (P = .005), the balance test (P = .01), the gait speed (P = .006), and the 5CS test (P = .03), resulting in the improvement of the functionality of individuals with MetS.
