Studies on Musculoskeletal Effects of Whole Body Vibration

Those people directing the studies are so convoluted [long-winded, complex,  or elaborate] that they don’t show whether the whole body vibration is effective [some studies show a minor additive effect on body composition and neuromuscular performance when using whole body vibration.   However, the following study indicates whole body vibration and the use of weights versus no weights, making the use of load [weights] as an increased benefit to the workout:

Evaluation of muscle activity for loaded [weights] and unloaded [no weights] dynamic squats during vertical whole-body vibration

The purpose of this investigation was to examine if the addition of a light external load [weights] would enhance whole-

body vibration (WBV)-induced increases in muscle activity during dynamic squatting in 4 leg muscles. Thirteen recreationally active male university students performed a series of dynamic squats (unloaded with no WBV, unloaded with WBV, loaded with no WBV, and loaded with WBV). The load was set to 30% of body mass and WBV included 25-, 35-, and 45-Hz frequencies with 4-mm amplitude. Muscle activity was recorded with surface electromyography (EMG) on the vastus lateralis (VL), biceps femoris (BF), tibialis anterior (TA), and gastrocnemius (GC) and is reported as EMGrms (root mean square) normalized to %maximal voluntary exertion. During unloaded dynamic squats, exposure to WBV (45 Hz) significantly (p < 0.05) increased baseline muscle activity in all muscles, except the TA compared with no WBV. Adding a [light external load without WBV increased baseline muscle activity of the squat exercise in all muscles but decreased the TA. This loaded level of muscle activity was further increased with WBV (45 Hz) in all muscles. The WBV-induced increases in muscle activity in the loaded condition (approximately 3.5%) were of a similar magnitude to the WBV-induced increases during the unloaded condition (approximately 2.5%) demonstrating the addition of WBV to unloaded or loaded dynamic squatting results in an increase in muscle activity. These results demonstrate the potential effectiveness of using external loads with exposure to WBV. [Brackets, italics, and font color were added for emphasis]

In the following study, 3 groups of women over the age of 65 were examined.  The group that used the whole body vibration with training (VTG) had the most effective workout, especially concerning muscle strength and power.  Compared to the Controlled Group (CG) who did not use whole body vibration, the VTG group training resulted in a significant increase of leg and trunk flexion [bending of joints] strength:

Whole Body Vibration Technology (Oscillation Model is Most Effective Type)

We examined whether the effect of multipurpose exercise can be enhanced by whole-body vibration (WBV). One hundred and fifty-one post-menopausal women (68.5+/-3.1 years) were randomly assigned to three groups: (1) a training group (TG); (2) training including vibration (VTG); and (3) a wellness control group (CG). TG and VTG performed the same training program twice weekly (60 min), consisting of aerobic and strength exercises, with the only difference that leg strength exercises (15 min) were performed with (VTG) or without (TG) vibration. CG performed a low-intensity “wellness” program. At baseline and after 18 months, body composition was determined using dual-X-ray-absorptiometry. Maximum isometric strength was determined for the legs and the trunk region. Leg power was measured by countermovement jumps using a force-measuring plate. In the TG lean body mass, total body fat, and abdominal fat were favorably affected, but no additive effects were generated by the vibration stimulus. However, concerning muscle strength and power, there was a tendency in favor of the VTG. Only vibration training resulted in a significant increase of leg and trunk flexion strength compared with CG. In summary, WBV embedded in a multipurpose exercise program showed minor additive effects on body composition and neuromuscular performance.
