  Abstract. Speed up recovery is fundamental in sport disciplines in which competitors must perform repeated trials within the same competition. The main objective of this study was to determine the effect of high-frequency whole body vibration (WBV) on blood [Lac] removal and heart rate (HR) after an all-out test. The participants performed a 4 x 100 m all-out test every 48 h in a random cross-over fashion, and a blood [Lac] removal protocol was applied after each test: a) 20 min seated (REST); b) squatting on a vibrating platform (S+V); and c) squatting on a non-vibrating platform (S-V). Blood [Lac] and HR were measured at rest, immediately after the 4 x 100 m all-out test (min 0), and at 10 and 20 min during the removal protocols. The results showed that the 3 protocols displayed significantly decreased blood [Lac] after 20 min (REST, S+V, and S-V removed Δ 6.6; Δ 10.5; and Δ 11.1 mmol∙L-1, respectively). However, there were no significant differences in the blood [Lac] removal level between the S+V and S-V conditions. Interestingly, the S-V participants showed increased HR levels during the active recovery compared with the REST and S+V conditions. The effect of high-frequency WBV is not an additional stimulus to increase the blood [Lac] removal capacity in active young men, although WBV appeared to elicit less cardiovascular stress during recovery.  Resumen. Acelerar la recuperación es fundamental en las disciplinas deportivas en las que los competidores deben realizar pruebas repetidas dentro de la misma competencia. El objetivo principal de este estudio fue determinar el efecto de la vibración de alta frecuencia de cuerpo completo (WBV) en la extracción de sangre [Lac] y la frecuencia cardíaca (FC) después de una prueba completa. Los participantes realizaron una prueba total de 4 x 100 m cada 48 h de forma aleatoria cruzada, y se aplicó un protocolo de extracción de sangre [Lac] después de cada prueba: a) 20 minutos sentado (REST); b) ponerse en cuclillas sobre una plataforma vibratoria (S+V); y c) ponerse en cuclillas en una plataforma no vibratoria (S-V). La sangre [Lac] y la FC se midieron en reposo, inmediatamente después de la prueba total de 4 x 100 m (min 0), y a los 10 y 20 min durante los protocolos de extracción. Los resultados mostraron que los 3 protocolos mostraron una disminución significativa de la sangre [Lac] después de 20 minutos (REST, S+V y S-V eliminaron Δ 6.6; Δ 10.5; y Δ 11.1 mmol ∙ L-1, respectivamente). Sin embargo, no hubo diferencias significativas en el nivel de eliminación de sangre [Lac] entre las condiciones S+V y S-V. Curiosamente, los participantes S-V mostraron mayores niveles de FC durante la recuperación activa en comparación con las condiciones REST y S+V. El efecto del WBV de alta frecuencia no es un estímulo adicional para aumentar la capacidad de eliminación de sangre [Lac] en hombres jóvenes activos, aunque el WBV parece provocar menos estrés cardiovascular durante la recuperación.

Cardiopulmonary Exercise

  In the last years the nervous and cardiovascular response to exercise has taken on an important relevance, both in sport and health field. In this line, accelerating cardiovascular appears to play a key role in various sports fields. The study aims to examine and compare the acute effect of whole-body vibration (WBV) on cardiac autonomic response after maximal exercise in university runners and physical education student. Twenty men participated in a cross-over study, 10 university runners team (UR) and 10 physical education student (PES) with ages around 18 to 24 years. In each condition, was perform an incremental cardiopulmonary exercise test followed (i) active recovery time using WBV (25 Hz and peak displacement of four mm) and (ii) passive recovery period (no WBV; 0 Hz—0 mm), separated by seven days. Active recovery consisted in one minute seated using WBV and one minute no WBV by six times (12 minutes) more five minutes of passive recovery, and passive recovery consisted in 17 min seated on platform without vibration. Active recovery had significant differences compare to passive recovery (P<0.05). Furthermore, in active recovery, PES had better heart rate response than UR group, however results were not significative. There was not a clear relation between the lineal components of heart rate variability (HRV) in our results. WBV has positive effect in participant’s recovery, however, is necessary establish protocols about the intensities and time adequate for allow accelerate recovery the parasympathetic reactivity, for that reason yet can’t conclude clearly respect to the more effectivity intensity WBV depending to characteristic of subject.  Resumen. En los últimos años la respuesta nerviosa y cardiovascular al ejercicio ha adquirido una relevancia importante, tanto en el ámbito del deporte como de la salud. Por tanto, la aceleración de la recuperación cardiovascular parece desempeñar un papel clave en varios campos. El objetivo del estudio es analizar y comparar el efecto agudo de la vibración de cuerpo completo (VCC), en la respuesta cardíaca autónoma después del ejercicio máximo en corredores universitarios (CU) y estudiantes de educación física (EEF). Veinte hombres participaron en un estudio cruzado, 10 CU y 10 EEF con edades entre 18 y 24 años. En cada evaluación, se realizó una prueba cardiopulmonar incremental seguida de (i) tiempo de recuperación activa usando VCC (25 Hz y desplazamiento máx. de cuatro mm) y (ii) período de recuperación pasiva (sin VCC; 0 Hz — 0 mm), separados por siete días. La recuperación activa consistió en un minuto sentado usando WBV y un minuto sin WBV seis veces (12 min), más cinco minutos de recuperación pasiva; la recuperación pasiva y esta consistió en 17 minutos sentado en plataforma sin vibración. La recuperación activa tuvo diferencias significativas en comparación con recuperación pasiva (p <0.05). Además, en recuperación activa, EEF tuvo una mejor respuesta de frecuencia cardíaca que el grupo CU, sin embargo, los resultados no fueron significativos. Por último, no se logró establecer una relación clara entre los componentes lineales de la variabilidad del ritmo cardiaco (VRC) en nuestros resultados. La VCC tiene un efecto positivo en la recuperación de los sujetos, sin embargo, es necesario establecer protocolos sobre las intensidades y tiempo adecuado para permitir acelerar la recuperación de la reactividad parasimpática, por esa razón aún no se puede concluir claramente respecto al mejor protocolo VVC dependiendo de la característica del sujeto.

Body Vibration

Research in humans suggests whole-body vibration (WBV) aids in maintaining bone mineral content (BMC) yet results in the horse are less favourable. Anecdotally, WBV is reported to reduce pain and improve performance. This study was designed to test the effect of WBV on exercising horses, hypothesising that WBV would lower heart rate (HR) during treatment, increase BMC, modify markers of bone metabolism, and increase stride length. Eleven horses were randomly assigned into control (CON, n=5) or WBV (VIB, n=6) groups for a 28-day treatment period. Both groups exercised for 1 h, 6 d/wk on a mechanical exerciser. VIB horses received 50 Hz WBV for 45 min, 5 days/wk. Third metacarpal radiographs were taken at 0 and 28 days, and BMC determined via radiographic bone aluminium equivalence (RBAE). Blood samples taken at day 0 and 28 were analysed for serum pyridinoline cross-links (PYD) and osteocalcin (OC). Heart rate was analysed on day 23 for 4 horses per group. Stride length was determined while trotting in hand on day 0 and 28. No influence of WBV on RBAE of any bone cortices, PYD or OC was observed (P>0.10); stride length was also unaffected (P=0.88). A period effect was observed for a decrease in RBAE of the lateral cortex (P=0.01), and a trend towards a decrease was noted in total density (P=0.05), likely an effect of stalling. Compared to baseline, ΔHR declined during treatment (P=0.06) in VIB (-4.8±2.8 bpm) compared to control CON (3.0±2.8 bpm). The results suggest, in normal exercising horses, WBV does not increase BMC, influence markers of bone metabolism, or increase stride length.

Delphi Studies

Whole-body vibration (WBV) is an exercise modality or treatment/prophylaxis method in which subjects (humans, animals, or cells) are exposed to mechanical vibrations through a vibrating platform or device. The vibrations are defined by their direction, frequency, magnitude, duration, and the number of daily bouts. Subjects can be exposed while performing exercises, hold postures, sitting, or lying down. Worldwide, WBV has attracted significant attention, and the number of studies is rising. To interpret, compare, and aggregate studies, the correct, complete, and consistent reporting of WBV-specific data (WBV parameters) is critical. Specific reporting guidelines aid in accomplishing this goal. There was a need to expand existing guidelines because of continuous developments in the field of WBV research, including but not limited to new outcome measures regarding brain function and cognition, modified designs of WBV platforms and attachments (e.g., mounting a chair on a platform), and comparisons of animal and cell culture studies with human studies. Based on Delphi studies among experts and using EQUATOR recommendations, we have developed extended reporting guidelines with checklists for human and animal/cell culture research, including information on devices, vibrations, administration, general protocol, and subjects. In addition, we provide explanations and examples of how to report. These new reporting guidelines are specific to WBV variables and do not target research designs in general. Researchers are encouraged to use the new WBV guidelines in addition to general design-specific guidelines.

Background: Whole-Body Vibration (WBV) consists of mechanical vibration stimuli produced that propagate throughout the body by increasing the gravitational load. The WBV can increase muscle mass in dogs with muscular atrophy. As Whole-body vibration (WBV) can be used as exercise modality with no impact on the joints, the present study aimed to evaluate the effects of single session of WBV in hematobiochemical and hemogasometric parameters in adult and elderly healthy dogs. Materials, Methods & Results: Fourteen clinically healthy, neutered crossbreed male dogs, non-athlete were selected. The dogs were divided into two groups of seven dogs, according to the age group: Group I - adult dogs (GI): age between 12.0 and 84.0 months old; Group II - elderly dogs (GII): age above 84.0 months old. All dogs were submitted to a single session WBV by using a vibrating platform that delivered a vortex wave circulation as mechanical vibration. The WBV protocol used was 30 Hz frequency (3.10 mm peak displacement; 11.16 m/s2 peak acceleration; 0.29 m/s velocity), then 50 Hz (3.98 mm peak displacement; 39.75 m/s2 peak acceleration; 0.62 m/s velocity), and lastly 30 Hz (3.10 mm peak displacement; 11.16 m/s2 peak acceleration; 0.29 m/s velocity) for 5-min between de frequencies. The hematobiochemical and hemagasometric parameters were evaluated at 1-min before the WBV session (1PRE), 1-min after the WBV session (1POST), 120-min (120POST) and 24 hours after the WBV session (24hPOST). The dogs accepted well the vibration stimulus, however, elderly dogs weighting above 30 kg were more likely to sit down with increased frequency from 30 to 50 Hz. No variations of food and water intakes and gastrointestinal changes were observed after the WBV session. Hemoglobin values showed significant decrease (P = 0.0312) between 1PRE and 1POST in elderly dogs. A significant decrease (P = 0.0453) was observed in alanine aminotransferase values between 120POST and 14hPOST in adult dogs. Creatinine values had a statically decrease (P = 0.0173) between 1PRE and 24hPOST in adult dogs. However, these values remained within the reference range for dogs. Discussion: According to the literature, there are no studies related to the effects of WBV in haematobiochemical and hemogasometric parameters in adult and elderly dogs. No deleterious effects regarding to a single session of WBV were observed, however harmful effects were observed in human patients. The elderly dogs with body mass above 30 kg tried to sit during the increased frequency from 30 to 50 Hz, which was associated with the pressure exerted in their paws. No significant differences were observed in erythrogram and leukogram parameters except for hemoglobin values. Significant decline was observed in hemoglobin values in adult Beagle dogs; and were associated with hemolysis. The significant decrease in alanine aminotransferase and creatinine values did not have clinical significance. No significant alterations were identified in hemogasometric parameters but slight increase in pH values was observed in horses subjected to a 60 km run, and was associated to the loss of Cl ions in sweat. The single session of WBV by using a vibrating platform that delivered a vortex wave circulation, at 30 and 50 Hz frequencies for 5 min did not induced significant changes in hematobiochemical and hemogasometric parameters in adults and elderly healthy dogs.
