Effects of Whole-Body Vibration Exercises on Parameters Related to the Sleep Quality in Metabolic Syndrome Individuals: A Clinical Trial Study

Metabolic syndrome (MetS) is an undesirable clinical condition with physiological, biochemical, clinical, and metabolic factors that contribute to increased cardiovascular risks (CR). A poor sleep quality might be found in obese and MetS individuals. Whole-body vibration (WBV) exercise has been used on the management of MetS individuals. This clinical trial investigated the effect of WBV exercise on parameters related to the sleep quality in MetS individuals. After randomization, nine individuals (seven women and two men) were exposed to a fixed frequency (FF) and ten individuals (eight women and two men) were exposed to a variable frequency (VF). Both groups performed the protocol twice a week, for 6 weeks. All of the evaluations were performed before the first and after the last sessions. Anthropometric and cardiovascular parameters were measured before and after the 6-week intervention. Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Berlin Questionnaire were also used to evaluate the quality of the sleep. A significant (p ≤ 0.05) reduction of the waist circumference in the VFG and an increase of the heart rate were found in the FFG and VFG group. The score of the PSQI of the both groups decreased significantly (p = 0.01). The score of the ESS decreased (p = 0.04) only in the VF group. The scores of the Berlin Questionnaire were not altered in both groups. In conclusion, WBV intervention was capable in interfering with physiological mechanisms with effects on the WC and HR, leading to the improvement of the quality of sleep in MetS individuals. WBV exercise might be an important clinical intervention to the management of some factors associated with poor quality of sleep (FFG and VFG) and in the daytime sleepiness in MetS individuals with variable frequencies (5–16 Hz) (VFG).

Effect of whole-body vibration exercise in the pelvic floor muscles of healthy and unhealthy individuals: a narrative review

The aim of this narrative review was to determine effects of whole body vibration exercises (WBVE) on the pelvic floor muscle (PFM) of healthy and unhealthy individuals. Searches were performed in the databases PubMed, Scopus, Science Direct and PEDRo. The level of evidence and methodological quality of the selected papers were determined. It was included six studies with a total of 189 participants (95.76% women) with ages ranging from 18 to 68 years. It was reported that WBVE: (I) improves the PFMs strength and quality of life (QOL) in individuals with urinary incontinence; (II) does not cause (PFM) fatigue in nulliparous continent women; (III) leads to higher (PFM) activation in subjects with weakened (PFM) and achieves higher pelvic floor (PF) activation than maximum voluntary contraction alone; (IV) in an individual with postprostatectomy stress urinary incontinence (SUI), over a period of 6 weeks after starting treatment, the patient regained continence (usage of 1 safety pad) and (V) has a significant effect on the electromyographic response and additionality and the rating of perceived exertion (RPE) significantly increased with increased frequency of the mechanical vibration. Relevant findings are presented and demonstrated that the WBVE might be highly relevant to the management of clinical disorders of the (PFM). Nevertheless, this intervention must be more understood and known to be used in the management of individuals with impairment of the (PFM) and there is the necessity of more research in this area.

Effects of whole-body vibration exercise for non-specific chronic low back pain: an assessor-blind, randomized controlled trial

Objective: To confirm the benefits of whole-body vibration exercise for pain intensity and functional disability in patients with non-specific chronic low back pain. Design: Single-blind randomized controlled trial. Setting: Outpatient. Subjects: Eighty-nine patients with non-specific chronic low back pain met the inclusion criteria, they were randomly allocated to either the intervention group (n = 45) or the control group (n = 44). Intervention: The intervention group received whole-body vibration exercises three times a week for 12 weeks. The control group received general exercise protocol three times a week for 12 weeks. Main outcomes: The primary outcome measures were pain intensity and functional disability measured by the visual analog scale scores and Oswestry Disability Index. The secondary outcome measures included lumbar joint position sense, quality of life (Short Form Health Survey 36) and overall treatment effect (Global Perceived Effect). Results: A total of 84 subjects completed the 12-week study program. After 12 weeks, compared with the control group, the mean visual analog scale and Oswestry Disability Index scores decreased by additional 1 point (95% confidence interval (CI) = –1.22 to −0.78; P < 0.001), 3.81 point (95% CI, −4.98, −2.63; P < 0.001) based on adjusted analysis in the intervention group. And the intervention group provided additional beneficial effects for in terms of lumbar joint position sense (P < 0.05), quality of life (P < 0.05), and Global Perceived Effect (P = 0.012). Conclusion: The study demonstrated that whole-body vibration exercise could provide more benefits than general exercise for relieving pain and improving functional disability in patients with non-specific chronic low back pain.

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.

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.

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.

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.

Effects of whole body vibration exercise on neuromuscular function for individuals with knee osteoarthritis: study protocol for a randomized controlled trial

BackgroundKnee osteoarthritis (KOA) is a leading cause of public disability. Neuromuscular function contributes to the development and/or progression of KOA. Whole body vibration (WBV) exercise improve the neuromuscular function of patients with neurological disorders and even that of older patients with limited exercise options. Therefore, WBV exercise may offer an efficient and alternative treatment for individuals with KOA. However, the effects of WBV training on the neuromuscular function of individuals with KOA remain unclear. Therefore, this study attempts to investigate the effect of a 12-week WBV exercise on the neuromuscular function of individuals with KOA.Methods/designWe will conduct a prospective, single-blind randomized controlled trial on 180 KOA patients. Participants will be randomly assigned to the WBV exercise, lower extremity resistance training, and health education groups. The WBV exercise group will participate in a 12-week WBV training. The lower extremity resistance training group will undergo a 12-week lower extremity resistance training of both lower limbs. The control group will receive health education for 12 weeks. After the intervention, the participants will be followed up for 3 months with no active intervention. Primary outcome measures will include anthropometric measurements, gait analysis during walking and stair climbing, muscle strength test of the knee and ankle, proprioception test of the knee and ankle, and neuromuscular response of the leg muscles. Secondary outcome measures will include self-reported pain and physical functional capacity, and physical performance measures. Furthermore, adverse events will be recorded and analyzed. If any participant withdraws from the trial, intention-to-treat analysis will be performed.DiscussionImportant features of this trial mainly include intervention setting, outcome measure selection, and study duration. This study is intended for estimating the effect of WBV intervention on neuromuscular control outcomes. Study results may provide evidence to support the beneficial effects of WBV exercise on the physical performance and neuromuscular control of individuals with KOA to fill the research gap on the efficacy of WBV.Trial registrationChinese Clinical Trial Registry, ID: ChiCTR-IOR-16009234.

Can whole body vibration exercises affect growth hormone concentration? A systematic review

Whole body vibration (WBV) has been recognized as an effective alternative exercise modality to resistance exercise for its ability in enhancing force and power, generating capacity in skeletal muscle, increasing bone mass and improving cardiovascular function. Since the effect of WBV exercises on growth hormone (GH) levels has been never compared and discussed, the aim of this study was to review systematically the literature to verify the WBV effects on GH concentration. By using PubMed, Scopus and PEDRo databases with the keywords ‘growth hormone’ or GH and ‘whole body vibration’ or WBV, we found and analysed 12 papers (182 subjects recruited), verifying their level of evidence (National Health and Medical Research Council hierarchy of evidence) and the methodological quality (PEDRo scale). Although WBV induced GH responses in nine out of 12 publications, caution should be however taken when considering the results due to the markedly different methodologies among these publications.

Effects of whole-body vibration exercise on bone mineral content and density in thermally injured children

BackgroundLoss of bone mass, muscle mass, and strength leads to significant disability in severely burned children. We assessed the effects of exercise combined with whole-body vibration (WBV) on bone mass, lean mass (LM), and muscle strength in children recovering from burns. MethodsNineteen burned children (≥30% total body surface area [TBSA] burns) were randomly assigned to a 6-week exercise regimen either alone (EX; n=10) or in combination with a 6-week WBV training regimen (EX+WBV; n=9). WBV was performed concurrent to the exercise regimen for 5days/week on a vibrating platform. Dual-energy X-ray absorptiometry quantified bone mineral content (BMC), bone mineral density (BMD), and LM; knee extension strength was assessed using isokinetic dynamometry before and after training. Alpha was set at p<0.05. ResultsBoth groups were similar in age, height, weight, TBSA burned, and length of hospitalization. Whole-body LM increased in the EX group (p=0.041) and trended toward an increase in the EX+WBV group (p=0.055). On the other hand, there were decreases in leg BMC for both groups (EX, p=0.011; EX+WBV, p=0.047), and in leg BMD for only the EX group (EX, p<0.001; EX+WBV, p=0.26). Truncal BMC decreased in only the EX group (EX, p=0.009; EX+WBV, p=0.61), while BMD decreased in both groups (EX, p<0.001; EX+WBV group, p<0.001). Leg strength increased over time in the EX group (p<0.001) and the EX+WBV group (p<0.001; between-group p=0.31). ConclusionsExercise in combination with WBV may help attenuate regional bone loss in children recovering from burns. Studies are needed to determine the optimal magnitude, frequency, and duration of the vibration protocol, with attention to minimizing any potential interference with wound healing and graft closure.

The effects of whole-body vibration exercise on isokinetic muscular function of the knee and jump performance depending on squatting position.

[Purpose] The purpose of this study was to investigate the effects of whole-body vibration exercise (WBVE) on isokinetic muscular function of the knee and jump performance depending on different squatting positions. [Subjects] The subjects were 12 healthy adult men who did not exercise regularly between the ages of 27 and 34. [Methods] WBVE was performed with high squat position (SP), middle SP, and low SP. Before and after the intervention, isokinetic muscular function of the knees and jump performance were measured. [Results] Knee flexion peak torque at 60°/s and total work at 180°/s were significantly increased after implementing WBVE. Jump height also significantly increased after completing the exercise at all positions in comparison with the pre-exercise programs. [Conclusion] The results of this study suggest that SP during WBVE is an important factor stimulating positive effects on muscular function.

Effect of whole-body vibration exercise in a sitting position prior to therapy on muscle tone and upper extremity function in stroke patients.

[Purpose] The purpose of this study was to determine the effect of whole-body vibration exercise in a sitting position prior to therapy in stroke patients. [Subjects and Methods] Fourteen chronic stroke patients were included in this study. Prior to occupational therapy, whole-body exercise was performed for 10 minutes, 5 times per week, for a total of 8 weeks. Muscle tone and upper extremity function were measured. The Modified Ashworth Scale (MAS) was used to measure muscle tone, and the Manual Function Test (MFT) and Fugl-Meyer Assessment scale (FugM) were used to measure upper extremity function. [Results] MAS score was significantly decreased, and MFT and FugM were significantly increased. [Conclusion] These results indicate that whole-body vibration exercise in a sitting position prior to therapy had a positive effect on muscle tone, and upper extremity function in stroke patients.

Comparison of whole-body vibration exercise and plyometric exercise to improve isokinetic muscular strength, jumping performance and balance of female volleyball players.

[Purpose] The purpose of this study was to assess the effect of whole-body vibration exercise and plyometric exercise on female volleyball players. [Subjects and Methods] Subjects were randomly allocated to two exercise groups (whole-body vibration exercise group and plyometric exercise group). The exercise was conducted three times each week for 8 weeks. Isokinetic muscular strength, jumping performance, and balance were measured before starting the exercise and after finishing the 8 weeks of exercise. [Results] Measurements of isokinetic muscular strength revealed that the whole-body vibration exercise group showed significant increase after the exercise. However, the plyometric exercise group had no significant increase in lumbar flexion, extension, and knee flexion. Measurements of vertical jumping revealed that, the whole-body vibration exercise group had no significant increase after the exercise. However, the plyometric exercise group showed significant increase. Measurements of balance revealed that, the whole-body vibration exercise group showed significant increase. However, the plyometric exercise group showed no significant increase. [Conclusion] Although both whole-body vibration and plyometric exercises are effective intervention methods, the two methods have different effects on the improvement of isokinetic muscular strength, jumping performance, and balance of female volleyball players.

Effects of whole-body vibration exercise on muscular strength and power, functional mobility and self-reported knee function in middle-aged and older Japanese women with knee pain.

Whole-body vibration training using vertical-vibration machines is called "acceleration training" (AT). The purpose of this study was to elucidate the effect of AT on lower-limb muscular strength and power, functional mobility and self-reported knee function in middle-aged and older Japanese women with knee pain. Thirty-eight middle-aged and older Japanese women (aged 50-73 years) with knee pain were divided into two groups: (1) the AT group (n=29) engaged in AT three times per week for eight weeks, and (2) the control group (C group, n=9). The AT program consisted of flexibility training, strength training of mainly the quadriceps and surrounding muscles and cool-down exercises. The C group was encouraged to perform the same or similar exercises at home without vibratory stimulus. We evaluated knee strength and power, functional mobility (timed up and go: TUG) and self-reported knee function (Japanese Knee Osteoarthritis Measure: JKOM). No one in the AT group dropped out during the program. All JKOM categories except degree of pain improved significantly post intervention indicating improved knee function, and TUG was significantly shorter in these participants. All knee strength and power parameters except isometric knee extension peak torque improved significantly. The degree of change in JKOM total score and TUG was significantly different between the two groups. Vibratory stimulus during an eight week AT programme can promote participation and safely improve functional mobility and self-reported knee function better than exercise without vibratory stimulus in middle-aged and older Japanese women with knee pain. level 2.
