Subjective Ratings of Whole-Body Vibration Training Platforms
The purpose of this research is to explore the use of whole-body vibration platforms commercially available in the health and sports sector. Experiments were conducted using two platforms providing a sinusoidal stimuli, one with a vertical (Platform 1) and one with a tilting action (Platform 2). A range of platform settings from 5 to 50 Hz were used. Comparison of these settings with the actual movement was made using a tri axial accelerometer mounted on the platforms to obtain the power spectrum density and magnitude of vibration (m/s² r.m.s.) weighted and unweighted. The participants stood on each of the platforms with a bent knee (angle of 130 •) for 30 seconds on each of 4 settings in a randomised order. Following each stimuli the participants were asked to rate the intensity of the experience using a numeric category ratio (CR100). The range of frequencies and magnitudes measured were approximately 5 to 39 Hz and 1 to 60 m/s² r.m.s. There was a positive correlation between mean subjective rating of intensity and magnitude of vibration. Subjective ratings of intensity per magnitude of vibration were greatest at 5 Hz and an increase in 1 m/s² r.m.s.weighted was equivalent to approximately 8 units on the CR100 scale. At comparable magnitude and frequency there was no significant difference in subjective response between the platforms. No correlation between age or Body Mass Index (BMI) and subjective rating of intensity were observed.

Background. Flexibility and muscular performance assist in maintaining posture, encourage effective movement, prevent improper body alignment, maintain proper muscle length and balance, and also lower the chance of injury. The neuromuscular training technique known as whole-body vibration (WBV) has recently gained favor in health and fitness facilities. WBV has long been utilized as a non-invasive, physical therapy aid in rehabilitation, to improve muscle performance (strength, power, and endurance), encourage bone formation, and decrease the risk of injury. Objective. The possibility of WBV exercise as a helpful and secure strategy for enhancing muscular performance and flexibility was therefore examined in the current review. Methods. The current narrative review used a search strategy and conducted a literature search in January 2023, retrieving data from the following databases: Web of Science, PubMed, Scopus, and Google Scholar. Results. Recommendations on how to increase muscle performance and flexibility, lower the chance of injury, and generally improve the overall quality of life are provided by the majority of the selected literature. Conclusions. The usage of this paradigm in practice increases muscle performance and flexibility in both healthy adult athletic and non-athletic subjects is proposed.

BACKGROUND: Whole-body vibration (WBV) is a neuromuscular training method that has recently received popularity in health and fitness centers, as an additional or substitute method to conventional training and therapy, in order to improve muscle strength and power. OBJECTIVE: The purpose of this review is to critically observe the effect of WBV training on neuromuscular performance in view of its ability to enhance the muscles strength, power, and flexibility; and also to investigate the influence of the different vibration characteristics (viz., method of application of vibration, frequency, and amplitude) and exercise protocols on the effect of this training. METHOD: For this review 24 studies or articles were examined, and based on exclusion and inclusion criteria, 5 studies were finally selected; and an attempt was made to uncover the factors influencing the improvement in neuromuscular performance as a result of WBV intervention. During the review, it was considered to include and discuss as many characteristics as possible, such as, knee extension, knee flexion, counter movement jump (CMJ), squat exercise, and jumping height (JH). RESULT: Whole-body vibration, along with additional exercise training, has a potential to induce substantial improvement in neuromuscular performance. CONCLUSION: Whole-body vibration can bring about improvement in muscles strength, power, and flexibility. The main factors associated with the improvement in muscles performance are range of amplitude and frequency, type of vibration and its method of application, training intensity, exercise protocol, and the characteristics of the participants.
Effect of whole-body-vibration training in institutionalized older adults
European Geriatric Medicine, 2013
The purpose of the present study was to determine the effect of whole body vibration training with a 1-month intervention period and 3-month no intervention follow up on cardiovascular diseases risk factors in inactive adults. Eleven inactive adults (age 47.45±6.05 years, height 160.24± 9.63 cm and body mass 72.42±6.98kg) were randomly chosen and took part in the study. Vibration training included 11-17 minutes of different positioning in frequency of 25-35Hz, done once a day for 30 sessions. Concentration of fasting blood sugar, total cholesterol, triglyceride, HDL and LDL were measured at three different intervals (baseline, immediately after 1month, after three months detraining). One-way repeated-measures analysis of variance and bonferroni-corrected paired t-tests were used to test for differences between the three intervals. Significance was set at p = 0.05. The results showed that Significant difference was detected in concentration of Fasting blood sugar (p=0.000), total cholesterol (p=0.050) and LDL-C (P=0.050) between three intervals. In contrast no significant difference was observed in concentration of triglyceride (p=0.818) and HDL-C (p=0.293) between all measured time units.In summary, triglyceride and HDL-C did not change significantly during the study period and follow-up, but there was a significant decrease of concentration of Fasting blood sugar, total cholesterol and LDL-C after 1 month compared to baseline. These data suggest that Whole body vibration training may have the potential to reduce cardiovascular diseases risk factors in inactive adults, thus inactive adults lacking stamina for doing exercise can be put for vibration training as an effective substitute.
A direct contact with vibratory surfaces have an effect on local and whole animal or human body. Nowadayswhole body vibrations are very basic and optional activities designed to shape and support physical rehabilitation and neuromuscular activityand specifically athletic performance which is common in gyms, sports shops, hotels and fitness rooms. But, it’s not a well-known modality for active, inactive people, and patients in Ethiopia. Indeed, availability of unsupervised vibration training and commercial provision of vibratory gym materials may led to trainees functional and structural body changes. Thus, this article aimed to reviews relevant publications reporting the body respond to vibration and delineate evidence-based implications to current knowledge of the effects of whole body vibration on body composition and musculoskeletal performance. A systematic literature search was performed in databases of Science Direct Scopus, and Google Scholar from 2003 to 2018. This review summarizes that the whole-body vibration has found a positive effect on body fat percentage, muscle, and bone function. Howe ever body composition can mostly have referenced with whole body vibration induced lean mass increment. A supervised vibration training given to healthy individuals and patients with reference to its contra-indications should have ample importance than free direct exposure.Thus, these findings could serve as a model for fitness trainers, club coaches, health care practitioners to implement whole body vibration as an exercise-based management intervention. Nevertheless, attention must be paid to different vibration load effects (i.e. frequency, exposure time, amplitude, and acceleration).In addition, whole body vibration training with additional low-risk and specific training are more advantageous.Key words: Body Composition, Musculoskeletal Function, Patient, Whole body vibration training

The aims of this study were to assess the behaviour of a vibrating platform under different conditions and to compare the effects of an 8-weeks periodised training programme with whole body vibration (WBV) alone or in combination with conventional strength training.Vibrating frequencies, displacements and peak accelerations were tested through a piezoelectric accelerometer under different conditions of load and subjects' position. Eighteen national level female athletes were assigned to one of three different groups performing WBV, conventional strength training (ST), or a combination of the two (WBV+ST). Isometric maximal voluntary contraction, dynamic maximal concentric force, and vertical jump tests were performed before and after the conditioning programme.Vibrating displacements and maximum accelerations measured on the device were not always consistent with their expected values calculated from the display and manufacturers' information (sinusoidal waveforms).

Whole body vibration improves body mass, flexibility and strength in previously sedentary adults
South African Journal of Sports Medicine
Objectives. This study aimed to determine the effectiveness of whole body vibration (WBV) training for promoting healthrelated physical fitness in sedentary adults. Design. A non-randomised sampling technique was used with an equivalent match-pair comparison group, pre-and posttest design. Volunteers were gathered through a combination of accidental and snowball sampling and divided into either the experimental (n=32) or control group (n=30). Dependent variables included body mass, hamstring flexibility as measured by the sit-and-reach test, upper-body strength as measured by a grip strength dynamometer, abdominal and upper-body muscular endurance as measured by 1-minute timed sit-up and push-up tests, respectively. The standardised YMCA fitness battery was used as the evaluation protocol. The WBV experimental group participated in a progressive 3 times/week training programme for a maximum duration of 30 minutes/session for 12 consecutive weeks. The control group remained sedentary. Results. Significant improvements in all five of the selected dependent parameters were measured. Conclusion. WBV training 3 times weekly for 30 minutes/ session provides an effective method of exercise intervention for health promotion in sedentary adults over a 12-week period.
