Although increased blood viscosity occurs in several cardiovascular diseases, little is known of factors influencing blood rheology in normal adults. Accordingly, we examined the relations of whole blood viscosity (WBV) to its rheologic determinants (hematocrit level, plasma viscosity, protein concentration, and red cell aggregability and rigidity), to demographic and laboratory variables, and ...

BACKGROUND Whole body vibration (WBV) exposure at work is common and studies found evidence that this exposure might cause low back pain (LBP). A recent review concluded there is a lack of evidence of effective strategies to reduce WBV exposure. Most research in this field is focussed on the technical implications, although changing behaviour towards WBV exposure might be promising as well. The...

Many professional truck drivers suffer from low back pain (LBP) which is thought to be associated with exposure to whole-body vibration (WBV). The objectives of this study were to: (i) characterize general health, regional body pain and WBV exposures, (ii) evaluate the associations between different WBV parameters and health outcomes, and (iii) determine whether there were factors which affect ...

BACKGROUND Whole body vibration (WBV) has been reported to exert growth hormone(GH)-releasing effects in healthy subjects. Despite the potential of WBV to positively affect body composition changes via lipolytic effects, few studies have been performed in obese subjects to date. METHODS This study evaluated the acute effects of WBV alone or in combination with squatting plus external load (WB...

Abnormalities in whole blood viscosity (WBV) have been implicated in hypertension. This study analyzes relations between WBV and blood pressure in the Strong Heart Study population of American Indians. We examined 676 participants (489 women, age 62 7 years) without prevalent cardiovascular disease or use of antihypertensive medications, digoxin, or aspirin. WBV was calculated from hematocrit a...

OBJECTIVES To study the tolerability of whole body vibration (WBV) exercise in patients with Duchenne muscular dystrophy (DMD) and its effects on muscle and bone. METHODS WBV was performed two to three times a week for three months. Motor function, muscle strength, bone mass and biochemical markers of bone and mineral metabolism were analyzed before and after the WBV period at 0, 3, 6 and 12 ...

Hyperglycaemia-induced oxidative stress is implicated as a cause of increased whole blood viscosity (WBV), which is a clinically modifiable risk factor for cardiovascular disease (CVD). However, whether or not there is variation in WBV at different stages of diabetes mellitus (DM) has yet to be confirmed. The sensitivity of underlying oxidative stress has also yet to be investigated. A total of...

This study investigated the effects of balance exercise combined with whole-body vibration (WBV) on step performance and lower limb muscle activity during simulated forward falls using the tether-release method in older women. Twenty older women were assigned to either a WBV plus balance exercise group (WBV, n=10) or a balance exercise without vibration group (standard balance exercise group [S...

CONTEXT Several groups have undertaken studies to evaluate the physiologic effects of whole-body vibration (WBV). However, the value of WBV in a training program remains unknown. OBJECTIVE To investigate whether a WBV program results in a better strength and postural control performance than an equivalent exercise program performed without vibration. DESIGN Randomized, controlled trial. S...

While it seems that whole body vibration (WBV) might be an effective modality to enhance physical performance, the proper prescription of WBV for performance enhancement remains unknown. The purpose of this study was to compare the immediate effect of various WBV accelerations on counter movement jump (CMJ) height, the duration of any effect, and differences between men and women. Forty-four pa...
