WHOLE-BODY VIBRATION TRAINING PROTOCOLS IN OBESE INDIVIDUALS: A SYSTEMATIC REVIEW

PROTOCOLOS DE TREINAMENTO DE VIBRAÇÃO DE CORPO INTEIRO EM OBESOS: UMA REVISÃO SISTEMÁTICA

PROTOCOLOS DE ENTRENAMIENTO DE VIBRACIÓN DE CUERPO ENTERO EN OBESOS: UNA REVISIÓN SISTEMÁTICA

ABSTRACT

Obesity is a chronic degenerative disease. Whole-body vibration (WBV) devices make it possible to control the intensity of exercises through their variables: frequency, amplitude and vibration time, thus enabling interventions in these populations. The objective of this study was to review the applications, protocols and results of WBV devices in obese individuals. A systematic literature review was conducted using the descriptors and terms verified in DeCS (LILACS and SCIELO) and MeSH (PubMED). Of the thirteen studies selected, seven used an experimental and six a quasi-experimental methodological design. Eleven studies analyzed chronic responses and two studies acute responses to WBV training. Frequency values ranged between 30 and 35 Hz, amplitude was around 2 mm, and in terms of intensity, most of the training protocols used a gradual increase in WBV throughout the intervention. Eight studies added dynamic exercises and extra loads to the WBV. The mean total WBV exposure time varied around 20’ distributed in 1 or 2 series, with vibration times of 30” to 60” and the same rest time. The mean frequency of interventions was around 2 to 3 times a week, with a mean intervention time of 10 months. The main results include: decrease in body weight and improvement in the physiological variables of oxygen absorption, bone mineral density and arterial profile, indicating that WBV can be a safe tool in the fight against obesity and its implications.

RESUMO

A obesidade é uma doença crônica degenerativa. Os aparelhos de vibração de corpo inteiro (VCI) permitem o controle da intensidade dos exercícios através das suas variáveis: frequência, amplitude e tempo de vibração, possibilitando intervenções nessas populações. O objetivo do presente estudo foi realizar uma revisão sobre as aplicações, protocolos e resultados dos aparelhos de VCI em indivíduos obesos. Realizou-se uma revisão sistemática da literatura utilizando os descritores e termos verificados no DeCS (LILACS e SCIELO) e no MeSH (PubMED). Dos 13 estudos selecionados, sete utilizaram o delineamento metodológico do tipo experimental e seis do tipo quase-experimental. Onze estudos analisaram as respostas crônicas e dois as respostas agudas ao treinamento com VCI. Os valores de frequência variaram entre 30 e 35 Hz, a amplitude, em torno de 2 mm, e, em relação à intensidade, a maioria dos protocolos de treinamento utilizara o aumento gradativo da VCI ao longo da intervenção. Oito estudos adicionaram exercícios dinâmicos e cargas extras à VCI. O tempo médio de exposição total à VCI variou em torno de 20’ distribuídos em 1 ou 2 séries, com tempos de 30” a 60” de vibração pelo mesmo tempo de descanso. A frequência média das intervenções foi em torno de 2 a 3 vezes por semana, com tempo médio de 10 meses de intervenção. Entre os principais resultados destacam-se: redução do peso corporal e melhoria nas variáveis fisiológicas da absorção de oxigênio, da densidade mineral óssea e do perfil arterial, indicando que a VCI pode ser uma ferramenta segura no combate à obesidade e suas implicações.

INTRODUCTION

Obesity is the excessive accumulation of body fat and is considered a chronic and progressive disease because it is associated with several comorbidities. The main cause of obesity is a sedentary lifestyle, but it can be associated with factors, such as eating disorders as well as genetic, endocrine, metabolic, psychological, and sociocultural issues.11.

Evidences have confirmed that the best strategies for reducing body weight and, consequently, mitigating the negative actions of obesity are behavioral changes and dietary restrictions; both strategies are associated with physical exercise.22.

New methodologies and equipment are emerging in an attempt to provide the public with new options for physical exercises that are less time-consuming and exposure, and offer improved results. Whole body vibration (WBV) devices, such as the vibratory platforms (VPs), stand out among the new options. These devices have led to an increase in research since their conception, seeking to identify their actions and effects in different populations.1111.

Exposure to vibration using a VP occurs through the contact of distal ends of the body segments. The effect produced from this contact can spread along many tissues before reaching the muscles and bones.3333. Luo J, McNamara B, Moran K.

Platforms currently available in the market allow one to select a wide range of variables that can be manipulated to maximize the final effects. These variables are amplitude (mm; from 2 mm to 10 mm), frequency (Hz; from 12 Hz to 50 Hz), and exposure time (from 30 seconds to 9 uninterrupted minutes). In addition to the combined aforementioned variables, it is possible to periodize training, correlating the number of sets performed in a session with weekly training frequency, and the duration of each series or the total program time.3636.

VPs offer several protocol possibilities. However, the combinations that produce the best effects when applied to obese populations are still unknown. Therefore, the objective of this systematic review was to investigate the most commonly used protocols for WBV training in obese individuals.

METHODS

Systematic review

The theoretical assumptions proposed by the Cochrane collaboration manual were used in this systematic review.3838. Tovey D. Methodological Expectations of Cochrane Intervention Reviews (MECIR). Standards for the conduct and reporting of new Cochrane Intervention Reviews 2012. The Cochrane Collaboration. 2013;2. All descriptors and terms were checked in the DeCS server (LILACS and SCIELO) and MeSH (PubMED).

The following inclusion criteria were considered:

  1. Studies published in indexed scientific journals from 2000 to 2017 in any language.

  2. Original studies linked to journals indexed in the selected databases that investigated the effects of WBV on obese individuals as the main or secondary objective

The exclusion criteria were:

  1. Incomplete studies (no results).

  2. Studies without identification of the authors or journal of publication.

  3. Studies in which vibration was not caused by a vibrating platform.

  4. Repeated studies, or studies meeting part of the inclusion criteria without presenting the vibration results separately, or another population were excluded, for preventing the main objective of this study.

Searches in the electronic databases were performed from June 26 to August 16, 2017, following the methodological recommendations for the systematic reviews.3939. Pereira MG, Galvão TF. Extração, avaliação da qualidade e síntese dos dados para revisão sistemática. Epidemiol Serv Saúde. 2014;23(3):577–8.

This review is part of a project approved by CNPq through the Public Notice number 446400/2014.

RESULTS

The descriptors used in the LILACS database were “Plataforma vibratória,” “Exercício vibratório,” “Treinamento vibratório,” “Vibração de corpo inteiro,” “Vibration of whole body,” “Vibratory plataforma,” “Vibración de cuerpo entero,” “obesidade,” “indivíduos obesos,” “adultos,” and “adultos obesos,” which were combined with the Boolean operators or/and. Sixteen potentially eligible articles were found in this database. After reading the titles and, in some cases, the abstracts, it was found that none of the publications dealt with full body vibration training for obese population as the main or secondary objective.

In the Scielo electronic database, the descriptors were used in various combinations, with the same Boolean operators already mentioned. Once again, no study relating the aspects of vibration training to obese populations was found.

The PubMed database was searched using the descriptors “Vibrating platform” (104), “Vibratory training” (154), “Vibrating exercise” (71), “Whole body vibration (1820),” “Obesity,” “Obese individuals,” and “Obese adults,” which were also combined with Boolean operators or/and.

The searches resulted in 118 potentially eligible publications. After reading the titles and, in some cases, the abstracts that showed potential, 88 were excluded because they did not meet the inclusion criteria adopted. After reading in full the 30 pre-selected studies, 17 were excluded. Hence, 13 studies were selected in the PubMed database for this systematic review, in accordance with the Figure 1.

DISCUSSION

Table 1 lists the summaries of the main revised studies that used VPs as an exercise intervention for obese populations.

Most WBV studies with obese individuals were performed with female participants, with BMI ranging from 25 gg/m22. Flegal KM, Graubard BI, Williamson DF, Gail MH.

The first two findings of this review were reports from Vissers et al.4040. Vissers D, Baeyens JP, Truijen S, Ides K, Vercruysse CC, Van Gaal L. The effect of whole body vibration short-term exercises on respiratory gas exchange in overweight and obese women. Phys Sportsmed. 2009;37(3):88-94. The first aimed to closely examine and compare improvement in oxygen uptake levels (O2) during resistance exercise (RE) sessions by adding IVC. In the second study, now a chronic context, vibratory exercises were associated with aerobic exercises (AE), in an attempt to identify if the results could positively affect body weight (BW), body composition (BC), BMI, heart rate (HR), and factors linked to metabolic syndrome (MS). Vissers et al.4040. Vissers D, Baeyens JP, Truijen S, Ides K, Vercruysse CC, Van Gaal L. The effect of whole body vibration short-term exercises on respiratory gas exchange in overweight and obese women. Phys Sportsmed. 2009;37(3):88-94. showed that carbon dioxide production (CO2) and absorption of oxygen (O2) were significantly higher in the group that performed the RE, in addition to the WBV, but did not show differences when the two groups were compared. The subjective perception of exertion (SPE) was also used to check the intensity of the exercises and showed greater evidence in the RE that was added to the vibration.

The second study4141. Vissers D, Verrijken A, Mertens I, Van Gils C, Van de Sompel A, Truijen S, et al. Effect of long-term whole body vibration training on visceral adipose tissue: a preliminary report. Obes Facts. 2010;3(2):93-100. was performed in a chronic way, with a sample of 61 sedentary women forming three groups: G1 (diet only), G2 (diet with EA exercises), G3 (diet in addition to WBV), and G4 corresponding to the control group (n = 21; no diet or exercise). The actions were followed by a six-month intervention, followed by another six months without intervention, amounting to a total of 12 months. The variables analyzed were BMI, BC, tomography, blood pressure (BP), blood count, resting ECG, and pulmonary function. The results showed that associating AE and WBV with a low-calorie diet may help maintain weight loss, especially visceral adipose tissue (VAT), as this marker plays a central role in metabolic syndrome. Weight loss in the 12-month interval was more effective in the AE and WBV groups than in the diet-only group. The diet-associated Vibration group was the only one to succeed in losing more than 10% of body weight at 6 months with maintenance up to 12 months. This led the authors to conclude that aerobic exercise that is associated with WBV in chronic form, in addition to a dietary control (low calorie diet), assists in reducing fat weight.

They associated WBV with radiofrequency through an electric wave emission device using adhesives placed on the distal regions of the body and trunk, with values of 75% of the maximum power of the device. However, the results showed no difference from the vibration-only group, such that the researchers decided to exclude radiofrequency and set up a single WBV-only group.

The devices used in the studies of this review were vibratory platforms and had protocols that can be manipulated using variables, such as frequency, amplitude, vibration intensity, and vibration duration.

Regarding the protocols used in the studies of this review, the most commonly used vibration frequency was between 30 Hz and 35 Hz. Of these, some maintained a single frequency of vibration without changes, while for others, such as, Vissers et al., Miyake et al., Figueroa et al., Oh et al., and Alvarez-Alvarado et al., this variable gradually increased.4040.

The effect of whole body vibration short-term exercises on respiratory gas exchange in overweight and obese women. Phys Sportsmed. 2009;37(3):88-94. was the only one to use a 4 mm amplitude. All studies also used the same amplitude values from start to finish. Only Figueroa et al.4545. Figueroa A, Gil R, Wong A, Hooshmand S, Park SY, Vicil F, et al. Whole-body vibration training reduces arterial stiffness, blood pressure and sympathovagal balance in young overweight/obese women. Hypertens Res. 2012;35(6):667–72. began their intervention with an amplitude of 1 mm, increasing to 2 mm. A similar procedure was adopted by Milanese et al.,4747. Milanese C, Piscitelli F, Zenti MG, Moghetti P, Sandri M, Zancanaro C. Ten-week Whole-body Vibration Training Improves Body Composition and Muscle Strength in Obese Women. Int J Med Sci. 2013;10(3):307-11. who began by applying amplitudes of 2 mm, increasing to 5 mm. Nam et al.5151. Nam SS, Sunoo S, Park HY, Moon HW. The effects of long-term whole-body vibration and aerobic exercise on body composition and bone mineral density in obese middle-aged women. J Exerc Nutrition Biochem. 2016;20(2):19-27. used the highest amplitude values of this review (6.8 mm), as a consequence of using a different VP model.

Some of the studies reviewed did not report vibration intensity values and did not elucidate why. Possibly, the vibration devices did not make this variable available or the researchers themselves did not choose to use it.4444. Wilms B, Frick J, Ernst B, Mueller R, Wirth B, Schultes B. Whole Body Vibration Added to Endurance Training in Obese Women - A Pilot Study. Int J Sports Med. 2012;33(09):740-3.

Some studies began and maintained the same vibration times, alternating with resting periods between sets. Song et al.4242. Song GE, Kim K, Lee DJ, Joo NS. Whole body vibration effects on body composition in the postmenopausal korean obese women: pilot study. Korean J Fam Med. 2011;32(7):399-405. began with a sample vibrating for 10’ in a single series. This is similar to Nam et al.,5151. Nam SS, Sunoo S, Park HY, Moon HW.

The total WBV time was near 19 minutes’. This fact was corroborated by the last 3 studies of this review, which also used protocols for gradually increasing the intensity.5050.

The first series was with the WBV in low intensity, after 30 seconds of rest, a second series started, with low vibration and the same time of 30 seconds; and the last series increased the intensity to high and the rest time to 1 minute, amounting to 40 minutes.

In addition, no one else used the largest amplitude (6.8 mm), which was adjusted every three months, increasing the vibration frequency according to the body mass of each participant.

Finally, Alvarez-Alvarado et al.5252. Alvarez-Alvarado S, Jaime SJ, Ormsbee MJ, Campbell JC, Post J, Pacilio J, et al. Benefits of whole-body vibration training on arterial function and muscle strength in young overweight/obese women. Hypertens Res. 2017;40(5):487-92. corroborated the previous studies, drafting a protocol that increased the vibration intensity, beginning with 30 seconds and reaching 1 minute. The exercises began with 2 sets and ended with 8, with the sessions ranging from 11 minutes to 30 minutes by the end of the research. The rest period was inversely proportional.

After this review, we can observe that the WBV protocols used in obese individuals met the following criteria regarding the vibration protocols: 6 used a single vibration from beginning to end, ranging from 16 Hz to 35 Hz, with 30 Hz prevailing. The other seven remaining studies used a gradual increase in frequency, which ranged from 16 Hz to 60 Hz, with 30 Hz to 35 Hz being more predominant.

Amplitude values used ranged from 1 mm to 6.8 mm, with 2 mm being the most used value. Seven studies did not inform what vibration intensity was used, whereas the others reposted having used an increasing intensity throughout the study, up until discharge.

The total time each individual was vibrating was at least 10 minutes and, at most, 40 minutes. Only one study used the 10-minute vibration time from beginning to the end. The others fractionated vibration with rest intervals between series. The prevailing vibration time of the others ranged from 30 seconds to 1 minute, followed by a rest interval of 30 seconds to 1 minute; but there were still 5- and 10-minute combinations.

The number of sessions most used was three times a week, highlighting the fact that three used vibration protocols once a week. In two studies, participants vibrated twice. Meanwhile, one study had a protocol of five times a week.

CONCLUSION

Regardless of the vibration protocol used, all research showed positive results when vibration was used alone or associated with other types of exercises. However, some values of these protocols were more common. The most used frequency values were 30 Hz and 35 Hz. The amplitude value that was most present was 2 mm. Most studies did not report intensity; however, those that did made gradual use of the frequency and intensity. That is, they began with smaller values and gradually increased. Regarding the time spent on the platform, most studies fractionated the total time in series, which had mean values between 30 seconds and 1 minute of vibration time, with the same values for rest. Most findings in this research used dynamic exercises associated with vibration for mostly lower limbs; although protocols performed statically also presented positive results. Finally, individuals remained vibrating for 20 to 30 minutes. The total intervention time of each study also varied widely, but the values that appeared most were 6, 8, and 12 weeks.

After analyzing the studies that comprise this review, certain aspects were selected as noteworthy for future research in this area.

- No studies found in the Portuguese language related body vibration to obese individuals, using any of the related variables, such as, age, gender, or physical, psychological, social, or ethnic characteristics.

- It is not clear what are the best protocols to use for overweight and obese people to combat this epidemic.
