Acute effect of whole body-vibration exercise and osteopathic manipulative treatment on the heart rate variability in individuals with metabolic syndrome: Randomized cross-study protocol

BackgroundMetabolic syndrome (MSy) is a risk factor for cardiovascular disease. The decrease in vagal activity has been related to the mechanism of MSy development. Recently, it has been proposed that the WBV exercise, as well as osteopathic manipulative treatment (OMT) stimulate cardiac autonomic modulation. AimThe aim of this study is to evaluate the acute effects of whole body-vibration (WBV) exercise and OMT on heart rate variability (HRV) in individuals with MSy. MethodsCross-sectional, randomized, cross-over study (one-week wash-out between interventions) and blinding analysis. Individuals with MSy will be randomized into 5 groups: 1) whole body-vibration exercise group (WBVG), 2) osteopathic manipulative treatment group (OMTG), 3) WBVG + OMTG, 4) OMTG + WBVG, 5) control group (CG). OMT will consist of suboccipital decompression technique, myofascial relaxation on cervical and diaphragm muscles. The HRV measurement will be done with the individual at rest, during the 2-min step test (2MST) and during interventions. After the treatment, the measurements will be repeated. DiscussionThe modulation of ANS is important in the management of MSy individuals. The investigation of intervention modalities to improve this modulation is necessary and it is expected that this protocol can promote this modulation and improve the HRV.

Effects of 12-week whole-body vibration exercise on fatigue, functional ability and quality of life in women with systemic lupus erythematosus: A randomized controlled trial

BackgroundSystemic lupus erythematosus (SLE) is a complex rheumatic autoimmune disease characterized by periods of exacerbations that can present damage in organs with important clinical manifestations. Objective: The aim of this study was to evaluate the effect of 12-week whole-body vibration exercise (WBVE) on the fatigue, functional ability and quality of life of women with systemic lupus erythematosus (SLE) in chronic glucocorticoids use (CGU). Methods: Twenty-one women were allocated randomly in the WBVE group or isometry group. The participants of WBVE group were positioned on the vibrating platform with 130° knee flexion and received the intervention twice a week for 12 weeks. The isometry group performed the same position and time, but without the stimulus of mechanical vibration. Fatigue, functional ability and the quality of life were evaluated at weeks 0, 6, and 12. Results: From a sample of seventy-seven individuals, seventeen participants completed the study, 8 in WBVE group and 9 in isometry group. Fatigue reduced in the WBVE group at 6 and 12 weeks of intervention (p = 0.04) and (p = 0.03) respectively. There was a significant improvement in the functional ability evaluated by the Health Assessment Questionnaire in the WBVE group compared to the isometry group (p = 0.03). Conclusion: WBVE would be a useful intervention for control of fatigue and improvement of the functional ability of women with SLE in CGU.

Acute Effects of Whole-Body Vibration Exercise on Pain Level, Functionality, and Rating of Exertion of Elderly Obese Knee Osteoarthritis Individuals: A Randomized Study

Introduction: Among chronic diseases, knee osteoarthritis (KOA) is a joint disease that causes important progressive alterations in the articular and periarticular structures, including synovial inflammation. Exercise has been suggested as an intervention to KOA individuals, and studies suggest that whole-body vibration (WBV) exercise decreases pain levels and favours the functionality of KOA individuals. Objective: The aim of the present study is to analyze the acute effects of WBV exercise on pain levels, functionality (Timed Up and Go (TUG test), anterior trunk flexion (ATF)), and rating of exertion of elderly obese KOA individuals. Methods: Thirty-seven individuals with KOA were allocated to a WBV exercise group (WBVEG), n = 19 (15 females/4 males), and a control group (CG), n = 18 (15 females/3 males). WBVEG performed one session of WBV exercise (11 min, using 5 Hz, 2.5, 5.0, and 7.5 mm, 0.12, 0.25, and 0.37 g). Three bouts were performed (working time of 3 min and rest time of 1 min) using a side-alternating vibrating platform (VP). The same position was used in CG; however, the VP was turned off and there was equipment coupled to the VP that emitted a sound like the vibrations. The pain level was evaluated using a visual analog scale (VAS). Functionality was evaluated with a TUG test and ATF. The rating of subjectively perceived exertion was measured with the category ratio CR-10 (BORG Scale CR-10), Results: A reduction of pain levels in WBVEG after the intervention (p = 0.001) and intergroups (p = 0.041) was found. A decrease of TUG test time in both groups (p = 0.001) and intergroups (p = 0.045) was found, while no statistical changes were observed in the Borg Scale score. Significant improvements of flexibility in both groups (p = 0.001) and intergroups (p = 0.043) were found. Conclusion: One session of WBV exercise can lead to important improvements in individuals with KOA, possibly triggered by physiological responses. However, more studies are needed, in this clinical context, to confirm these results.

Effects of Whole-Body Vibration Training on the Physical Function of the Frail Elderly: An Open, Randomized Controlled Trial

ObjectiveTo investigate the feasibility and benefits of whole-body vibration (WBV) exercise as a safe and effective training tool for countering sarcopenia and age-related declines in mobility and function in the frail elderly. DesignAn open, randomized controlled trial. SettingResidential care facilities. ParticipantsMale and female volunteers (N=117; 82.5±7.9y). InterventionsAfter prescreening for contraindications, participants were randomly allocated to a control, simulated WBV (SIM), or WBV exercise group. All participants received regular care, whereas WBV and SIM participants also underwent thrice-weekly exercise sessions for 16 weeks. Delivered by overload principle, WBV training began with 5 × 1-minute bouts at 6 Hz/2 mm (1:1 min exercise:rest), progressing to 10 × 1 minute at up to 26 Hz/4 mm, maintaining knee flexion. Training for SIM participants mimicked WBV exercise stance and duration only. Main Outcome MeasuresThe timed Up and Go, Parallel Walk, and 10-m Timed Walk (10mTW) tests performance were assessed, in addition to the Barthel Index Questionnaire, at baseline, 8, and 16 weeks of exercise, and 3, 6, and 12 months postexercise. ResultsHigh levels of compliance were reported in SIM (89%) and WBV training (93%), with ease of use and no adverse effects. In comparison to baseline levels, WBV training elicited clinically important treatment effects in all parameters compared to SIM and control groups. Treatment effects remained apparent up to 12 months postintervention for Parallel Walk Test and 6 months for 10mTW Test. Functional test performance declined during and postintervention in non-WBV groups. ConclusionsFindings indicate that 16 weeks of low-level WBV exercise provides easily accessible, adequate stimulus for the frail elderly to attain improved levels of physical functionality.

Can whole body vibration exercises promote improvement on quality of life and on chronic pain level of metabolic syndrome patients? A pseudorandomized crossover study.

Quality of life (QoL) is one of the most important health outcome concepts expressed subjectively. Chronic pain (CP) is an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Taking into account the poor QoL and the CP already described in metabolic syndrome (MSy) individuals, this study aimed to evaluate the effects of whole body vibration exercises (WBVE) on these parameters in this population. Thirty-three MSy patients were divided in subgroups A [whole body vibration exercise group (WBVeG), n = 17, 15 females/2 males, 61.1 ± 8.4 yr] and B (control group, n = 16, 14 females/2 males, 58.2 ± 9.1 yr). Subgroup A performed 10 sessions (2 times/wk) of WBVE (18 min/session, with a frequency from 5 up to 14 Hz and a peak-to-peak displacement of 2.5, 5.0, and 7.5 mm) on a side-alternating vibrating platform (VP). Subgroup B did the same protocol, but the VP was turned off. The individuals answered the World Health Organization Quality of Life bref (WHOQoL-bref) questionnaire before the first and after the 10th session. The chronic pain level (CPL) was measured by a numeric rating scale (0-10) before and at the end of each session. Significant improvements were found in physical health (P = 0.05) and psychological health (P = 0.04) domains of WHOQoL-bref in WBVeG. A significant acute reduction of the CPL was found in the WBVeG after the protocol, considering the first session and at the last session. WBVE marginally improved physical health and psychological health and decrease the CPL in acute interventions.NEW & NOTEWORTHY Metabolic syndrome patients experience poor quality of life, frequently associated with lack of exercise and bad dietary habits. Additionally, factors such as obesity, neuromusculoskeletal impairment, and peripheral endothelial dysfunction result in a chronic pain level. Whole body vibration exercise might represent a suitable physical therapy, since it is easy to perform, low cost, safe, and capable of promoting an improvement of quality of life and reducing chronic pain level during acute interventions in metabolic syndrome individuals.

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.

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.

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.

The effects of gymnastics and whole-body vibration exercises on some physical fitness parameters

The purpose of this study was to comparatively analyze the effects of 6 weeks of gymnastics and whole body vibration exercises on some physical fitness parameters. Twenty two male subjects participated in this research (Age average 21.4 ± 2.4 and height average 1.75 ± 5.6 cm). Participants were randomly assigned to three groups; Gymnastics and Whole-body Vibration Exercise Group (GWBVEG, n=7), Gymnastics Exercise Group (GEG, n=8) and Control Group (CG, n=7). Muscle strength, endurance and flexibility were measured before and after 6 week-exercise period. For data analyses Wilcoxon Signed Ranks Test was used in order to look at the differences among the dependant groups and Mann Whitney U test was used in order to to look at the differences among the independant groups. When the groups’ post-tests for physical performance values were compared, it was observed that the improvement of muscle strength and endurance values of the GWBVEG group was significantly higher than the one for GEG and CG groups (p>0.05). As a result, it is suggested that the whole-body vibration in gymnastics can be considered as an important criteria for the improvement of endurance, muscle strength and flexibility.

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.

Changes in body balance and functional performance following whole-body vibration training in patients with fibromyalgia syndrome: A randomized controlled trial

To determine whether an 8-week exercise programme supplemented with whole-body vibration improves body balance and dynamic strength in women with fibromyalgia. Randomized controlled trial. Forty-six participants diagnosed with fibromyalgia. Participants were randomly assigned to: (i) an exercise training group with whole-body vibration (n = 15), which performed twice-weekly exercise sessions (aerobic exercise, strengthening and flexibility) combined with 3 whole-body vibration training sessions a week (bilateral squats: 6-9 sets of 30 s with 45-s recovery between sets; and unilateral squat: 4-7 sets of 30 s, 30 Hz-4 mm); (ii) an exercise group (n = 15) with the same combined exercise therapy; and (iii) a usual-care control group (n = 16). Statistically significant improvements in the Medio-Lateral Stability Index and Medio-Lateral Mean Deflection with open eyes were found in the whole-body vibration exercise group compared with the control group. Non-significant effects were found for lower-limb physical function. The results show that a traditional exercise programme, supplemented with whole-body vibration training, improved balance in women with fibromyalgia. This may represent a key factor for falls prevention in this patient group.
