Objective: To analyze the effects of whole body vibration on electromyographic activity of the core muscles.
Methods: This is an observational cross-sectional study composed of 30 males who practice physical activity. The amplitude of the electromyographic activation (Root Mean Square - RMS) of the rectus abdominis, external oblique, longissimus thoracis, multifidus muscles were evaluated during supine bridge, side plank and frontal plank exercises, performed with and without vibration (frequency: 50 Hz and amplitude: 4 mm). A significance level of 5% was assigned for all analyzes.
Results: Whole body vibration did not alter the amplitude of electromyographic activity for any of the evaluated muscle groups, showing no difference between the conditions with and without vibration during the performance of the proposed exercises.
Conclusion: Under the conditions analyzed in this study, the vibrating platform does not change the activation amplitude of core muscles, suggesting that the use of whole body vibration is not necessary as an additional method to increase muscle activity during stabilization exercises in healthy men.

Despite the high incidence of knee injuries reported in non-professional sports, the implementation of specific training programmes aimed at mitigating the kinematic and kinetic factors associated with these injuries remains limited. To determine the effects of a tailored exercise programme on kinematic and kinetic variables during side-cutting activities. Fifty-seven physically active participants were randomised into control group (CG; n: 28) that received no intervention, and an experimental group (EG; n: 29), that performed an individualised exercise programme that included a combination of strength, neuromuscular, proprioceptive, eccentric training and whole-body vibration (WBV) exercises.

Background And Aims: The prevalence of Metabolic Dysfunction-Associated Steatotic Liver Disease has increased in parallel with a rise in consumption of ultra-processed foods (UPF), but little is known about their association.
Methods: We cross-sectionally examined associations of UPF with hepatic steatosis and fibrosis in 2,458 (mean age 54 years; 55.9% women) community-dwelling adults who completed vibration-controlled transient elastography and a food frequency questionnaire.

Background Aims: Non-invasive tests (NITs), e.g. Fibrosis-4 Index (FIB-4) and vibration-controlled elastography (VCTE), have been used to identify metabolic dysfunction-associated steatotic liver disease (MASLD) patients at high risks for hepatocellular carcinoma (HCC).

Lumbar motor control is an important factor for the prevention and improvement of low back pain and the enhancement of sports performance. Interventions for lumbar motor control are complex and difficult; however, training with whole-body vibrations has the potential to be simple and effective. Therefore, this study aimed to verify the effects of 4 weeks of trunk training with whole-body vibrations on each component of lumbar motor control.

Transmissibility is used to assess dynamic responses of the occupant-seat system, and most studies have exclusively assessed the transmissibility from the floor to the cushion or the backrest surface with the human body. In this investigation, the vertical vibration transmitted from the floor to six specific locations both on the seat surface and the frame when the seat was fixed on three positions on the track was examined utilizing an SAE J826 manikin and 12 male adults (0.25 to 20 Hz) for a duration of 120 seconds at three vibration amplitudes.
