“…The second mechanism proposed is neurophysiological in nature as the vibration training elicited a tonic vibration reflex that activated the muscle spindles and led to the advancement of the stretch-reflex loop. 18,19 Significant increases in upper-body muscle strength (as measured by grip strength) by using WBV training were in agreement with findings that have previously been reported for training-induced strength gains. Muscular strength scores for absolute grip strength increased by 87% over the intervention period as compared with those of their sedentary counterparts.…”

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.S Afr J SM 2012;24(2):60-64.

“…Chronic low back pain, vascular disorders, or postural perturbations are directly caused by prolonged exposure to WBV in the work environment (e.g. Carlsöö 1982;Seidel and Heide 1986;Tiemessen et al 2007;Wasserman et al 1997). Some cases of visual impairment or dizziness occur minutes or hours after work, including when employees are driving home, as reported by the Organisme Professionnel de Prévention du Bâtiment et des Travaux Publics (OPPBTP 2006).…”

Countering postural posteffects following prolonged exposure to whole-body vibration: a sensorimotor treatment

et al. 2008

Postural stability of bulldozer operators after a day of work is investigated. When operators are no longer exposed to whole-body vibration (WBV) generated by their vehicle, their sensorimotor coordination and body representation remain altered. A sensorimotor treatment based on a set of customized voluntary movements is tested to counter and prevent potential post-work accidents due to prolonged exposure to WBV. This treatment includes muscle stretching, joint rotations, and plantar pressures, all known to minimize the deleterious effects of prolonged exposure to mechanical vibrations. The postural stability of participants (drivers; N = 12) was assessed via the area of an ellipse computed from the X and Y displacements of the center-of-pressure (CoP) in the horizontal plane when they executed a simple balance task before driving, after driving, and after driving and having performed the sensorimotor treatment. An ancillary experiment is also reported in which a group of non-driver participants (N = 12) performed the same postural task three times during the same day but without exposure to WBV or the sensorimotor treatment. Prolonged exposure to WBV significantly increased postural instability in bulldozer drivers after they operated their vehicle compared to prior to their day of work. The sensorimotor treatment allowed postural stability to return to a level that was not significantly different from that before driving. The results reveal that (1) the postural system remains perturbed after prolonged exposure to WBV due to operating a bulldozer and (2) treatment immediately after driving provides a "sensorimotor recalibration" and a significant decrease in WBV-induced postural instability. If confirmed in different contexts, the postural re-stabilizing effect of the sensorimotor treatment would constitute a simple, rapid, inexpensive, and efficient means to prevent post-work accidents due to balance-related issues.

“…It was further noted by Village (Village et al 1995) that muscles respond to vibration in order to stabilise the spine and minimise upper body motion to preserve a seated posture when sitting. Carlsoo (1982) commented that vibration can alter the perception of intensity of the contraction and tension in muscles, so muscles may be perceived as being longer than their actual length (Eklund 1972). As a consequence, postural adjustments can result, which may lead to offsets in balance (Eklund 1972).…”

“…As a consequence, postural adjustments can result, which may lead to offsets in balance (Eklund 1972). This response is dependent on the level of receptor activity and the length of the muscle (Carlsoo 1982), and in general, muscle sensitivity is dependant on the amplitude and frequency of the vibrating source (Eklund 1972).…”
