“…Moreover, higher WBV intensities (1.11‐7.00 g) led to higher levels of muscle activation in bilateral MG (paretic: +54.8%‐269.3%; non‐paretic: +49.3%‐301.0%), TA (paretic: +43.7%‐221.9%; non‐paretic: +93.4%‐573.4%), and MH (paretic: +129.7%‐230.4%; non‐paretic: +44.6%‐136.5%). These values are generally in line with those reported in previous studies in young healthy adults, older adults, and stroke patients when using a similar EMG processing method. The degree of muscle activation induced by WBV was higher than that in the young healthy population.…”

Purpose This study aimed to investigate the influence of whole‐body vibration (WBV) frequency, amplitude, and body posture on lower limb muscle activation among people with chronic stroke, and whether the EMG response to vibration stimulus differed between paretic and non‐paretic side. The relationship between muscle activation and WBV transmission was also examined. Method Thirty‐two participants with chronic stroke performed three different exercises on the WBV platform with different vibration conditions (frequency: 20 Hz, 30 Hz, 40 Hz; amplitude: 0.8 mm, 1.5 mm), or without vibration. Muscle activity in bilateral vastus medialis (VM), medial hamstrings (MH), tibialis anterior (TA), and medial gastrocnemius (MG) was measured by surface electromyography. Acceleration at the platform and bilateral hips and knees was measured by tri‐axial accelerometers. Results Significantly greater muscle activity was observed in the bilateral MG (P < 0.001), TA (P < 0.001), and MH (P < 0.001), but not VM, compared with the same exercises without WBV. WBV with higher amplitude or higher frequency led to greater augmentation of muscle activation (P < 0.05). Body posture significantly affected leg muscle activation (P < 0.001). WBV‐induced muscle activation was largely similar between paretic and non‐paretic sides, except the TA. Greater WBV‐induced leg muscle activation was associated with lower WBV transmissibility measured at the more proximal joints (P < 0.05). Conclusion Adding WBV to exercise significantly increased muscle activation in the MG, TA, and MH on both the paretic and non‐paretic sides of chronic stroke survivors, and the increase was dependent on the WBV amplitude, frequency, and body posture.

“…Several studies have reported an increase in lower limb muscle activity during exposure to WBV in healthy young adults, older adults, and stroke survivors, as measured by surface electromyography (EMG). However, randomized controlled trials on the effect of WBV treatment on leg muscle strength have yielded mixed results .…”

“…The older population may show greater increases in lower limb muscle activity during WBV exercise than their young counterparts, which means that they might benefit more from WBV exercises. [ 31 ] Our analysis however shows that compared to the elderly, statistically significant improvement in lean mass or muscle mass was found in younger adults. Furthermore, excluding the athletic participants did not change the result, which may support the application of WBVT in young adults for the sake of maintaining or augmenting muscle mass.…”

“…High-frequency and high-acceleration WBVT may be more effective than low frequency in ameliorating aged-induced muscle loss in people and middle-aged mice. [ 31 , 32 ] In various vibration frequencies, average electromyography root mean square activity of vastus lateralis was higher than in the no-vibration condition, and the electromyography root mean square was different in vastus lateralis muscle during WBVT conducted with diverse protocols. [ 33 ] Therefore, further studies are required to explore the optimal protocol of WBV during clinical practice.…”

Background:Whole-body vibration training (WBVT) confers a continuous vibration stimuli to the body. Although some reports have discussed the effects of whole-body vibration (WBV) on bone mineral density and muscle strength, study of WBV effects on lean mass have not been determined. The purpose of the present meta-analysis was to evaluate published, randomized controlled trials (RCTs) that investigated the effects of WBVT on lean mass.Methods:We identified only RCTs by searching databases, including Web of Science, PubMed, Scopus, Embase, and the Cochrane Library from inception to March 2017. Data extraction, quality assessment, and meta-analysis were performed.Results:Ten RCTs with 5 RCTs concentrating on older people, 3 on young adults, and 2 on children and adolescents were included. We additionally explored the effect of WBVT on postmenopausal women (6 trials from the 10 trials). Significant improvements in lean mass with WBVT were merely found in young adults (P = .02) but not in other populations compared to control group.Conclusion:The effect of WBVT found in the present meta-analysis may be used in counteracting the loss of muscle mass in younger adults. Moreover, optimal WBVT protocols for greater muscle hypertrophy are expected to be investigated.

“…In recent years, there has been increasing interest in whole-body vibration training (WBVT) as a form of exercise, especially among the elderly. 6 , 7 WBVT is done on a platform that generates vertical sinusoidal vibrations, which stimulate muscle spindles and produce muscular contractions similar to tonic reflexes. 8 …”

ObjectiveEvaluate cardiac, metabolic, and ventilatory changes during a training session with whole-body vibration training (WBVT) with 3 different frequencies in patients with chronic obstructive pulmonary disease (COPD).MethodsThis was a prospective, interventional trial in outpatients with severe COPD. Participants performed 3 vertical WBVT sessions once a week using frequencies of 35, 25 Hz and no vibration in squatting position (isometric). Cardiac, metabolic, and ventilator parameters were monitored during the sessions using an ergospirometer. Changes in oxygen pulse response (VO2/HR) at the different frequencies were the primary outcome of the study.ResultsThirty-two male patients with a mean forced expiratory volume in 1 second of 39.7% completed the study. Compared to the reference of 35 Hz, VO2/HR at no vibration was 10.7% lower (P=0.005); however, no statistically significant differences were observed on comparing the frequencies of 35 and 25 Hz. The median oxygen uptake (VO2) at 25 Hz and no vibration was 9.43% and 13.9% lower, respectively, compared to that obtained at 35 Hz (both comparisons P<0.0001). The median expiratory volume without vibration was 9.43% lower than the VO2 at the end of the assessment at 35 Hz vibration (P=0.002).ConclusionVertical WBVT training sessions show greater cardiac, metabolic, and respiratory responses compared with the squat position. On comparing the 2 frequencies used, we observed that the frequency of 35 Hz provides higher cardiorespiratory adaptation.
