“…A number of scientific reports show a positive effect of physical activity on body composition [2]. In the literature, we can also find evidence of the positive impact of vibrations with stochastic resonance on other aspects of the human body, e.g., balance, muscle pain, and cognitive functions [9][10][11]. The impact of stochastic resonance whole body vibrations on individual parameters of female body composition have never been studied before.…”

According to the WHO, overweight and obesity, defined as abnormal or excessive fat accumulation, are a major risk factor for many diseases. The bioelectrical impedance analysis (BIA) is a commonly used method of assessing body composition in clinical practice and medical research. When the BIA reveals abnormalities, the recommended therapeutic procedure is to modify the diet and implement physical activity. One method that can reinforce or support physical activity is whole-body vibration (WBV). Vibrating devices with stochastic resonance (SR) generate vibrations of variable amplitude and frequency. For people with unhealthy body composition who cannot undertake physical activity for various reasons, procedures with stochastic resonance seems to be a good solution. The aim of this study was to evaluate the impact of stochastic resonance whole-body vibration (SR-WBV) on the body composition of women. Measured BC parameters included fat mass (FM, kg), percent body fat (PBF, %), visceral fat area (VFA, cm2), soft lean mass (SLM, kg), fat-free mass (FFM, kg), skeletal muscle mass (SMM, kg), body cell mass (BCM, kg), protein (kg), minerals (kg), bone mineral contents (BMC, kg), intracellular water (IW, l), extracellular water (EW, l), total body water (TBW, l), extracellular water/total body water (EW/TBW). The study involved 240 healthy young women with normal body composition (BC) and low or moderate physical activity levels. Two groups were randomly formed from among all participants: the V group included 134 women participating in 12 SR-WBV procedure sessions over 6 weeks; the C group included 106 women not participating in SR-WBV procedure sessions over 6 weeks. The stochastic procedure consisted of 12 sessions over 6 weeks. One session lasted 15 min, consisting of nine active series of vibrations lasting 45 s each with 40 s breaks between series. The vibration frequency was 2–8 Hz and the amplitude ranged 0.5–3.5 mm. While observing the effect of SR-WBV vibrations on body composition in the group of women, no statistically significant changes were found. Hence, we conclude that the stochastic resonance vibration procedure cannot be recommended as a way to modify body composition in healthy young women characterized by normal body composition and low or moderate physical activity levels.

“…Laird et al (2005) describes cognitive interference to be the difference between incongruent items and a control condition, either congruent, neutral, or non-lexical items (75). Analogous to a previous study on cognitive effects from SR-WBV (76), congruent items are compared to neutral items in the present study. A higher difference between both conditions means higher cognitive interference and thus lower inhibitory control (77).…”

A good body-balance helps to prevent slips, trips and falls. New body-balance interventions must be explored, because effective methods to implement daily training are sparse. The purpose of the current study was to investigate acute effects of side-alternating whole-body vibration (SS-WBV) training on musculoskeletal well-being, flexibility, body balance, and cognition. In this randomized controlled trial, participants were randomly allocated into a verum (8.5 Hz, SS-WBV, N = 28) or sham (6 Hz, SS-WBV, N = 27) condition. The training consisted of three SS-WBV series that lasted one-minute each with two one-minute breaks in between. During the SS-WBV series, participants stood in the middle of the platform with slightly bent knees. During the breaks in between, participants could loosen up. Flexibility (modified fingertip-to-floor method), balance (modified Star Excursion Balance Test), and cognitive interference (Stroop Color Word Test) were tested before and after the exercise. Also, musculoskeletal well-being, muscle relaxation, sense of flexibility, sense of balance, and surefootedness were assessed in a questionnaire before and after the exercise. Musculoskeletal well-being was significantly increased only after verum. Also, muscle relaxation was significantly higher only after verum. The Flexibility-Test showed significant improvement after both conditions. Accordingly, sense of flexibility was significantly increased after both conditions. The Balance-Test showed significant improvement after verum, and after sham. Accordingly, increased sense of balance was significant after both conditions. However, surefootedness was significantly higher only after verum. The Stroop-Test showed significant improvement only after verum. The current study shows that one SS-WBV training session increases musculoskeletal well-being, flexibility, body balance and cognition. The abundance of improvements on a light and portable platform has great influence on the practicability of training in daily life, aiming to prevent slip trips and falls at work.
