Background:Aerobic exercise training is associated with lower central arterial stiffness, but little information exists on the effects of physical activity intensity or duration stiffness. Using a cross-sectional and interventional approach, we tested hypothesis that both moderate vigorous reduce stiffness in postmenopausal women.
This paper presents experimental research evaluation of the vibration exposure for health risk prediction during vehicle operation. The measurements were carried out on a recreational and two types agricultural tractors. levels measured different surfaces speed conditions. Based analysis results in small tractor operated workplace (frameworks), Sed exceeded 0.80 MPa by ISO2631-5:2004, Av 0.89 m/s(2) ISO2631-1:1997. That means that operators driving tractors more than 8 h day have high...
Abstract A national study in Malaysia was conducted with the main objective being to determine prevalence of musculoskeletal disorders (MSDs) and association between risk factors MSDs among Malaysian bus drivers. Cross‐sectional data were collected from 1,181 male commercial drivers using questionnaires demographic, working characteristics a translated Nordic questionnaire MSD complaints. Human Vibration Meter used measure whole body vibration (WBV) exposure, postural analysis evaluate...
Although much is known about human body vibration discomfort, there little research data on the effects of vehicle occupant drowsiness. A laboratory experimental setup has been developed. Vibration was applied to volunteers sitting seat mounted platform. Seated were exposed a Gaussian random vibration, with 1-15 Hz frequency bandwidth at 0.2 ms(-2) r.m.s., for 20-minutes. Two drowsiness measurement methods used, Psychomotor Vigilance Test (PVT) and Karolinska Sleepiness Scale (KSS)....
Vibrotactile thresholds on the finger have been compared using two alternative systems. One system prescribed push force, contact and surround, while this was not defined for other system. The experiment performed with nine male subjects attending three different days. It found that systems yielded vibrotactile which were significantly different. dependence of frequency vibration, area conditions surrounding area, temperature, distortion waveform must be considered when quantifying thresholds.
The apparent mass and seat-to-head-transmissibility response functions of the seated human body are investigated under exposures to fore-aft (x), lateral (y), combined (x y) axis whole-body vibration. experiments were performed study effects hands support, back support vibration magnitude on interactions with seat pan backrest, characterised in terms masses transmitted head single dual-axis horizontal data acquired 9 subjects exposed two different magnitudes applied along individual x- y-...
Real-world whole-body vibration exposures comprise motion in fore–aft, lateral, and vertical directions simultaneously. There can also be components of roll, pitch, yaw. If evaluating with respect to human response, most investigators will use methods defined ISO 2631-1. This uses frequency weightings that were originally derived from laboratory studies the subjective responses one direction at a time. paper describes experiments carried out using 6 degree-of-freedom simulator validate...
<h3>Objectives</h3> The dose–response relationship for hand-transmitted vibration has been investigated extensively in temperate environments. Since the clinical features of hand-arm syndrome (HAVS) differ between and tropical environment, we conducted this study to investigate HAVS a environment. <h3>Methods</h3> A total 173 male construction, forestry automobile manufacturing plant workers Malaysia were recruited into August 2011 2012. participants interviewed history exposure symptoms,...
This study aimed to explore the clinical characteristics of hand arm vibration syndrome (HAVS) in a group tree fellers tropical environment. We examined all and selected control subjects logging camp central Sarawak for exposure presence HAVS symptoms utilizing vibrotactile perception threshold test (VPT) cold water provocation (CWP). None reported white finger. The significantly higher prevalence finger coldness as compared (OR=10.32, 95%CI=1.21–87.94). A lower skin temperature, longer...
This study aims to investigate the effects of whole-body vibration (WBV) exposure on disturbance standing balance function assuming that cause slip, trip and fall accidents in land transportation industry is related WBV when traveling vehicles. In experiment, ten participants underwent 60 min virtual driving a simulator (DS) for exposure. addition, measurements were conducted before exposure, immediately after 2 4 Four conditions considered by combining two magnitudes driver passenger...
Temporary threshold shifts (TTSs) in vibrotactile perception produced by continuous vibration and repetitive shock have been investigated. Subjects were exposed to vertical hand-transmitted 100 Hz various shocks of equal energy content formed from one complete cycle a sine wave. The repetition rate the cycles was 5, 25, 50, or s-1 while root-mean-square (rms) acceleration measured over exposures five minutes held constant at 2.5, 10 ms-2 rms (weighted according British Standard (BS) 6842...
Exposure to whole-body vibration is generally accepted as being a risk factor for low back pain and therefore exposure should be minimised. The results of previous laboratory based research investigating the biomechanical response seated human has been used develop models that can within tools are capable predicting seats. Several studies in literature have reported apparent masses subjects whilst exposed either random or sinusoidal vibration. Although these shown similar trends, there no...
The purpose of this study was to investigate the apparent mass sitting human body and compare it with current experimental data ISO 5982 standard impedance model.The seated in vertical direction measured. Twelve male subjects were exposed random whole-body vibration frequency range (1-20 Hz), a excitation level 1.0 m/s2 r.m.s. posture upright no backrest contact.The obtained masses compared International Standard, (ISO 5982). biodynamic response Japanese peaked 4-6.5 Hz range, which is...
