| Summary: | This study evaluated the suitability of the vibration dose value (VDV) and action and limit values from the EU Directive 2002/44/EC in assessing lower back health risks due to repeated shocks using common horse riding as an example. The difference between pelvis- and saddle-based VDV calculations was assessed. VDVs were calculated from accelerations measured using inertial measurement units (IMUs) on the saddle and the rider’s pelvis during walking (30 min) and cantering (10 min). Saddle and pelvis VDVs were similar, 12–31 m/s<sup>1.75</sup> for walking and 46–69 m/s<sup>1.75</sup> for cantering. Accelerations reached the action value (9.1 m/s<sup>1.75</sup>) within 03:16 min of walking and 00:08 min of cantering. Accelerations reached the limit value (21 m/s<sup>1.75</sup>) within 30:00 min or 00:26 min of cantering. Although VDV reached limits quickly, walking and cantering are generally harmless for the lower back. Application of the VDV and associated limits for repeated shocks assessment might need reconsideration. |
