The biomechanical stress that can be tolerated by people of average constitution in minor car crashes is widely disputed. Important biomechanical loadings occur not only in car crashes but also in some activities of our daily life. They do obviously not cause whiplash or other spinal disorders. In order to obtain reliable values we measured the accelerational stress in some of these actives, using the same instrumental setup as for the volunteers during vehicle crashes.
We conclude that some biomechanical loadings of daily living, sports and leisure occupations are comparable to low-speed vehicle accidents with alleged whiplash injuries: The acceleration loading and the kinematic response of the body are similar – some examples are presented. A offer a concise mathematical description for the biomechanical, whose parameters can be directly compared to those in collision events.
