Background: Falling is the second leading cause of injury-related death worldwide and is a leading cause of injury among older adults. Whole-body vibration has been used to improve fall risk factors in older adults. No study has assessed if vibration benefits can be retained over time. Objectives: The aims of this study were to examine if six-weeks of whole-body vibration could improve fall risk factors and to assess if benefits associated with the training program could be sustained two months following the final training session. Design and Setting: Repeated measures randomized controlled design. Participants: Twenty-four independent living older adults were recruited and were randomly assigned to the WBV or control group. Intervention: Participants performed three sessions of whole-body vibration training per week with a vibration frequency of 20Hz or with only an audio recording of the vibration noise. An assessment of fall risk factors was performed prior to, immediately following, and two-months after the completion of the training program. Main Outcome Measures: Fall risk factors including functional capacity, mobility, strength, and walking speed were assessed pre-training, post-training, and two-months post-training. Results: Seventeen participants completed the study. No improvements (p<0.05) between groups were found in the measures of physical performance. Conclusions: Findings revealed that six weeks of whole-body vibration is not effective in improving fall risk factors or producing benefits post-training.

Objective: The aim of this study was to verify the influence of 6 weeks of whole-body vibration training on the pro- and anti-inflammatory cytokines (IL-2, IL-4, IL-6, IL-10, IFN-ɣ e TNF-α) in young, eutrophic and sedentary women. Methods: Twenty-six participants were randomly divided into two groups: Vibratory Platform Group (GV, n = 13) and Ergometry Group (GE, n = 13). The training program of both groups was of 20 minutes / session, 3 times per week, in non-consecutive days for 6 weeks. The load of the training was adjusted with the adapted Borg scale. GE was submitted to aerobic activity sessions in a cycle ergometer. GV was submitted to vibration platform stimulation sessions. After training program both groups were submitted to 6 weeks of detraining. Results: GV increased levels of IL-4, IL-6, IL-10 and TNF-α after training, and it decreased all of them after detraining phase. GE increased IL2, IL-4, IL-6 and IL-10 only after the detraining period. Conclusion: 6 weeks of whole-body vibration training can promote an increase in pro- and anti-inflammatory cytokines in young, eutrophic and sedentary women, however these effects seem to be transitory as the exercise is discontinued.

Context:Whole-body-vibration (WBV) stimulus equipment has been used as a new training method for health promotion. Its use in the clinic has expanded to the field of sports and rehabilitation for disabled patients. WBV training is rapidly gaining popularity in health and fitness centers as an alternative method for improving muscle performance. Acute positive effects of WBV have been shown on lower-extremity muscle power and vertical-jump ability; however, there have not been any studies focusing on the long-term effects of WBV for trunk muscle and dynamic balance.Objective:To investigate the effects of an 8-wk program of WBV in combination with trunk-muscle training on muscle performance in healthy, untrained adults.Design:Laboratory-based, repeated-measures study.Setting:University laboratory.Participants:20 healthy university men.Intervention:Participants were randomly assigned to a WBV or non-WBV group. The WBV group performed a trunk-muscle-training program in combination with WBV; the non-WBV group performed the same muscle-training program without WBV for 8 wk.Main Outcome Measures:In the pre- and posttraining period, the participants were evaluated using the Functional Movement Screen (FMS), Y Balance Test (Y-test) (anterior, posteromedial, and posterolateral reach), trunk-muscle isometric strength (flexor, extensor, and flexor:extensor ratio), squat jump, and countermovement jump.Results:The WBV group had greater improvement than the non-WBV group in both trunk-flexor muscle strength (P = .02) and the Y-test (anterior reach) (P = .004) between pre- and posttraining.Conclusion:Adding WBV to a trunk-muscle-strengthening program may improve trunk-flexor isometric strength and anterior reach during the Y-test more than training without WBV. The WBV protocol used in this study had no significant impact on FMS scores, squat jumping, countermovement jumping, trunk-extensor isometric strength, or trunk flexor:extensor ratio.

Abstract Context: Whole-body vibration machines are a relatively new technology being implemented in the athletic setting. Numerous authors have examined the proposed physiologic mechanisms of vibration therapy and performance outcomes. Changes have mainly been observed in the lower extremity after individual exercises, with minimal attention to the upper extremity and resistance training programs. Objective: To examine the effects of a novel vibration intervention directed at the upper extremity as a precursor to a supervised, multijoint dynamic resistance training program. Design: Randomized controlled trial. Setting: National Collegiate Athletic Association Division IA institution. Patients or Other Participants: Thirteen female student-athletes were divided into the following 2 treatment groups: (1) whole-body vibration and resistance training or (2) resistance training only. Intervention(s): Participants in the vibration and resistance training group used an experimental vibration protocol of 2 × 60 seconds at 4 mm and 50 Hz, in a modified push-up position, 3 times per week for 10 weeks, just before their supervised resistance training session. Main Outcome Measure(s): Isokinetic total work measurements of the rotator cuff were collected at baseline and at week 5 and week 10. Results: No differences were found between the treatment groups (P &gt; .05). However, rotator cuff output across time increased in both groups (P &lt; .05). Conclusions: Although findings did not differ between the groups, the use of whole-body vibration as a precursor to multijoint exercises warrants further investigation because of the current lack of literature on the topic. Our results indicate that indirectly strengthening the rotator cuff using a multijoint dynamic resistance training program is possible.
