The aim of this study was to investigate the effect of adding whole-body vibration (WBV; frequency = 35 to 40 Hz; amplitude = 4 mm) to squat training on the T-cell proliferative response of elderly patients with osteoarthritis (OA) of the knee. This study was a randomized controlled trial in which the selected variables were assessed before and after 12 weeks of training. Twenty-six subjects (7...

Many professional truck drivers experience low back pain (LBP) which is believed to be associated with exposure to whole body vibration (WBV). As a part of a randomized controlled trial, this study measured WBV exposures from 98 professional truck drivers continuously during their regular work shift (8-12 hours). The daily weighted average A(8), vibration dose value VDV(8), and vector sum A(8) ...

Blood viscosity is a crucial hemodynamic biomarker because it determines the friction against blood vessels, the quantity of oxygen that is delivered to organs and tissues, and the degree of exertion by the heart. Many factors affect blood viscosity, either directly or inversely. e.g., fibrinogen and hematocrit. The effect of other factors (e.g., cholesterol) on blood viscosity is still under i...

The acute effect of whole-body vibration (WBV) training may enhance muscular performance via neural potentiation of the stretch reflex. The purpose of this study was to investigate if acute WBV exposure affects the stretch induced knee jerk reflex [onset latency and electromechanical delay (EMD)] and the isokinetic knee extensor peak torque performance. Twenty-two subjects were randomly assigne...

OBJECTIVES Stochastic resonance whole body vibrations (SR-WBV) may reduce and prevent musculoskeletal problems (MSP). The aim of this study was to evaluate how activities of the lumbar erector spinae (ES) and of the ascending and descending trapezius (TA, TD) change in upright standing position during SR-WBV. METHODS Nineteen female subjects completed 12 series of 10 seconds of SR-WBV at six ...

Injury to the central nervous system often results in impairments that negatively affect walking function. Prior evidence suggests that vibration may improve walking function. The purpose of this study was to determine whether repeated use of whole-body vibration (WBV) is associated with improvements in walking function in individuals with spinal cord injury (SCI). Subjects were 17 individuals ...

BACKGROUND Whole body vibration (WBV) exercises have been investigated as an alternative and complementary method to traditional resistance programs for fitness improvements in healthy subjects. Active militaries must have a high fitness level and have to improve some physical abilities to accomplish some specific tasks in Army, as climb ropes, climb walls and pull up. MATERIALS AND METHODS S...

OBJECTIVES To evaluate the effects of whole-body vibration (WBV) on skeletal muscle activity and power performance of the upper body during decline bench press exercise at different loads. METHODS Forty-seven healthy young and active male students volunteered. Each performed dynamic decline bench press repetitions with and without WBV (50 Hz, 2.2 mm) applied through a hamstring bridge exercis...

Whole body vibration (WBV) has been linked to lower back disorders (LBD’s). The purpose of this study is to determine whether crane operators are exposed to whole body vibration (WBV). If exposure exists then, do they exceed a current consensus standard. This information will be used to determine whether WBV should become a larger discussion item when purchasing cranes and or rebuilding. This i...

The aim of this systematic review was to identify and evaluate the evidence of the efficacy of stochastic resonance whole-body vibration (SR-WBV) on static, dynamic and functional balance in the elderly and in patients with neurodegenerative diseases. English and German studies were consulted in the CINAHL, Cochrane Central Register of Controlled Trials, ISI Web of Knowledge, PEDro and PubMed d...
