Abstract
Bus drivers are exposed to whole body vibration (WBV) during their workday. Vibration is a physical agent capable of unleashing serious health risks, and when overexposed, is commonly associated with low back pain. The objectives of the present research were to obtain whole body acceleration in urban transport drivers that execute four different routes, based on ISO 2631-1 and Occupational Hygiene Standard (NHO 09) and to verify if there is a correlation between body mass index or percentage of body fat and acceleration. The elaboration and application of an anamnesis questionnaire was carried out aiming at the qualitative characterization of the co-partner's drivers regarding their health and their perceptions related to the vibratory stimuli present in their workplace. The results of the questionnaire showed that the vibration bothers a significant part of the drivers and that the complaint of pain is mainly concentrated in the region of the lumbar spine. The results of the experimental measurements of vibration pointed out that the vertical axis (Z) is the one with the highest values of weighted acceleration. The analysis of the correlation between the values of fat percentage or body mass index (BMI) with acceleration resulting from partial exposure suggests that there is interaction of two or more factors with BMI and percentage of fat, which generate the acceleration result. That is, the acceleration is not affected solely and individually by the BMI or fat percentage.
