The influence of seat backrest angle on perceived discomfort during exposure to vertical whole-body vibration.
UNLABELLED National and International Standards (e.g. BS 6841 and ISO 2631-1) provide methodologies for the measurement and assessment of whole-body vibration in terms of comfort and health. The EU Physical Agents (Vibration) Directive (PAVD) provides criteria by which vibration magnitudes can be assessed. However, these standards only consider upright seated (90°) and recumbent (0°) backrest a...
متن کاملTransmission of vertical whole body vibration to the human body.
According to experimental studies, low-amplitude high-frequency vibration is anabolic to bone tissue, whereas in clinical trials, the bone effects have varied. Given the potential of whole body vibration in bone training, this study aimed at exploring the transmission of vertical sinusoidal vibration to the human body over a wide range of applicable amplitudes (from 0.05 to 3 mm) and frequencie...
متن کاملVibration exposure and biodynamic responses during whole-body vibration training.
PURPOSE Excessive, chronic whole-body vibration (WBV) has a number of negative side effects on the human body, including disorders of the skeletal, digestive, reproductive, visual, and vestibular systems. Whole-body vibration training (WBVT) is intentional exposure to WBV to increase leg muscle strength, bone mineral density, health-related quality of life, and decrease back pain. The purpose o...
متن کاملSeat selection guidelines to reduce whole-body vibration exposure levels in the SA mining industry
The short-term and long-term consequences of whole-body vibration (WBV) have been shown to adversely affect occupational health and safety. Some of these effects can lead to permanent disabilities, especially to muscoskeletal, spinal and gastro-intestinal disorders (Boshuizen and Hulshof1). One of the most common complaints from personnel exposed to high levels of WBV is that of lower back pain...
متن کاملThe in uence of seat backrest angle on human performance during whole-body vibration
This study investigated the effects of reclined backrest angles on cognitive and psychomotor tasks during exposure to vertical whole-body vibration. Twenty participants were each exposed to three test stimuli of vertical vibration: 2–8 Hz; 8–14 Hz and 14– 20 Hz, plus a stationary control condition whilst seated on a vibration platform at five backrest angles: 0° (recumbent, supine) to 90° (upri...
