Horse riding is common in many occupations; however, there is currently no research evaluating exposure to whole-body vibration and mechanical shock on horseback.
Whole-body vibration was measured on a cattle rancher during two 30 min horseback rides using a tri-axial accelerometer mounted on a western saddle. Vibration was summarized into standardized metrics, including the 8 hr equivalent root-mean-squared acceleration (A[8]) and the daily 4th power vibration dose value (VDV). The resulting exposures were compared to the exposure limit and action values provided by European Union Directive 2002/44/EC.
The highest vibration for both rides was in the vertical axis, with average A(8) and VDV of 0.56 m/s and 26.24 m/s , respectively. The A(8) value indicated moderate risk while the VDV suggested high risk of harmful health effects.

骑马在许多职业中都很常见；然而，目前尚无研究评估骑马时全身振动和机械冲击的暴露情况。
在一位牧场主骑马的两个30分钟过程中，使用安装在西部马鞍上的三轴加速度计测量全身振动。振动被汇总为标准化指标，包括8小时等效均方根加速度（A[8]）和每日四次方振动剂量值（VDV）。将所得暴露情况与欧盟指令2002/44/EC规定的暴露限值和行动值进行比较。
两次骑行中最高振动均出现在垂直轴上，平均A(8)和VDV分别为0.56 m/s和26.24 m/s 。A(8)值表明存在中度风险，而VDV表明对健康有有害影响的高风险。
